Regular Chapter Meetings

The student chapter held the board meetings on bi-weekly basis. For most of the general meetings, they were held in association with Chapter’s events, such as research seminar series and outreach activity.

Seminar Series 1: Joyner Lecture

2015-2016 Annual Report, May 6, 2016 Iowa State University Student Chapter of the Earthquake Engineering Research Institute page 4

Figure 1. Joyner Lecture with Dr. Paul Somerville in EERI seminar series

Seminar Speaker: Dr. Paul Somerville is an engineering seismologist now at AECOM (formerly at its predecessor organizations URS and Woodward-Clyde) in Los Angeles.

We had the privilege of welcoming Dr. Somerville to Iowa State. He gave a presentation entitled “Geoscientists’ Capacity to Supply Engineers’ Demands for Seismic Hazard Inputs.” This Joyner Lecture, co-organized by EERI ISU Student Chapter, attracted more than 20 graduate and undergraduate students from structural to geotechnical engineering. He investigated physical causes of the remarkably large degree of predictable variability in earthquake ground motions, and their representation in design ground motions in the spectral and time domains. Moreover, he emphasized that it is always beneficial to document the progress in the understanding and quantification of seismic hazards for application in engineering practice in case histories which date back to early applications of modern theoretical seismology and plate tectonic theory. After his talk, he had a lunch with EERI advisors and student cabinet members, followed by a short tour of Iowa State University.

Seminar Series 2:

Seminar Speaker: Dr. Zachary Haber is a bridge research engineer with Professional Service Industries, Inc. He serves as a contractor for the Federal Highway Administration at the Turner-Fairbank Highway Research Center in McLean, Virginia.

He gave a presentation entitled “Seismic and Non-Seismic Performance of Prefabricated Element Connections for Accelerated Bridge Construction”. His presentation covered a number topics related to the design and performance of prefabricated element connections for accelerated bridge construction (ABC) projects. Prefabricated structure elements were discussed along with considerations for both seismic and non-seismic loading.

Seminar Series 3: Wilson Seminar

Seminar Speaker: Dr. Hitoshi Shiohara is a professor in the Department of Architectural Engineering of the University of Tokyo in Japan.

His presentation was entitled “Recent Advances in Beam-Column Joint Design and Seismic Collapse Simulation on Reinforced Concrete Frame Buildings”. This Wilson Seminar, co-organized by EERI ISU Student Chapter, attracted more than 20 graduate and undergraduate students and some faculty members in structural engineering. He introduced a new concept of joint hinging that having been developed for seismic design

2015-2016 Annual Report, May 6, 2016 Iowa State University Student Chapter of the Earthquake Engineering Research Institute page 5

consideration in Japan. Furthermore, His presentation discussed about seismic collapse simulation for moment frames with BC joints failing in the joint hinging, and the challenge of strength degradation and severe pinching hysteretic behavior inherent to the joint hinging. In the end, he gave draft equations to quantify the strength of joint hinging of BC joints based on a new provision in the New AIJ (Architectural Institute of Japan) Standard for Seismic Capacity Calculation.

Seminar Series 4:

Figure 2. Dr. Richard Henry’s presentation in EERI Seminar Series

Seminar Speaker: Dr. Richard Henry is a senior lecturer in the Department of Civil and Environmental Engineering at the University of Auckland. During his PhD studies he spent over a year on exchange to Iowa State University as part of the Fulbright scholarship program. Rick is a technical committee member of the New Zealand Concrete Structures Standard (NZS 3101) and is a council member of the New Zealand Concrete Society.

He presented a seminar entitled “Performance Based Seismic Design of RC Buildings and Traditional Constructions.” In this Fulbright Outreach Lecturing Fund Seminar, which was co-organized by EERI ISU Student Chapter, the theory and practical application of nonlinear analysis and performance-based design in terms and analogies that are very familiar to the engineer will be presented. His visit consisted of one hour lecture, a lab tour in Iowa State University Structural Laboratory, and an informal dinner with EERI advisor and ISU Student Chapter officers.

Outreach Activit ies

Science Night

On Tuesday February 16th several of our students had the opportunity to participate in the 2016 Edwards’ elementary school science night. For this event we were to create a positive experience for the younger generation that would hopefully provide them with an excitement to continue to learn. To accomplish this we brought some posters presenting basic information about earthquakes. We then had the students participate in an activity where they were to build a structure of their choice using k’nex on a shake table to be tested. This was an enjoyable experience for everyone involved and we will definitely be looking forward to expanding on it next year.

The student chapter volunteered as a student organization in the Iowa State University Office of Pre-collegiate Program for Talented and Gifted which is geared to middle school age student (6th -8th grade) on March 10th. The event attracted nearly 200 elementary students attend this year and the student chapter gave presentations for two sessions. Dr. Ashlock and Catalina Parada who works as an undergraduate research assistant with Dr. Ashlock, presented the liquefaction demonstration and gave brief presentation about earthquake engineering. EERI student members (Zhiyan Jiang, Rose Cui, Jacob Eull (board member) and Bin Cai (board member)) provided sets of equipment for hands-on activities and briefly introduced the concepts of seismic design to the students through the construction of K’Nex structures.

Chapter Advertisement and SDC Team Recruitment

In the welcome picnic for new students entering in fall 2015, hosted by Department of Civil, Construction and Environmental Engineering (CCEE) at Iowa State University, the student chapter took the opportunity to showcase our organization and promote excitement for the CCEE students. Similar chapter activities were also taken place in the spring and fall club fest hosted by the college of engineering and the student activity center. In the end of spring semester, EERI board members, helped by formal SDC members, advertised their future plan for the upcoming seismic design competition in spring 2016. They eventually recruited around 10 people and formed the 2016 SDC team.

SEISMIC DESIGN COMPETITION TEAM

The Iowa State University SDC Team this year was formed in early September. The team used most of the resources from the last few years, held meetings bi-weekly and more frequently when it was closer to the competition.

Team Results and Lessons Learned

This year, Iowa State University placed 18th at the Undergraduate Seismic Design Competition held in San Francisco, California. For many of the students, it was their first time participating in this event and needless to say, we all enjoyed the journey. This year, the members included Jacob Eull, Phuong Vo, Chao Zhou, Jacob Verry, Jason Xu, and Kelvin Chu. The group had a mixture of majors that consists of civil engineering, economics, and environmental science, and it was this unique difference that made a strong team. Some of the skills we have gained this past year include learning how to operate machinery such as a band saw, learning computer programs such as Revit and SAP2000, and how to fundraise successfully. In total, we raised over $5,000 which allowed us to buy necessities such as balsa wood and plane tickets. Although faced with many problematic issues regarding construction and planning of the model, we worked hard to overcome all adversities.

We are thankful to have been a part of this competition, and we are excited for next year’s competition in Portland, Oregon. Having become more experienced, we hope to place higher next year. Some of the changes we will implement include running tests such as flexure tests early on in the year, creating a larger team, and building at least two structures in order to achieve the most optimal model. Below are some pictures from our club.

What is ?

Geoscientists’ Capacity to Supply Engineers’ Demands for Seismic Hazard Inputs 2015 Joyner Lecture: Paul Somerville, PhD

Co-organized with EERI Iowa State University Student Chapter

Monday, September 21st 11-12, 270 Town Engineering Building

Engineers usually require probabilistic expressions of seismic hazard, which require extensive knowledge of earthquake phenomena from geoscientists. The physical causes of the remarkably large degree of predictable variability in earthquake ground motions are explored, and their representation in design ground motions in the spectral and time domains is described. Progress in the understanding and quantification of seismic hazards for application in engineering practice is documented in case histories which date back to early applications of modern theoretical seismology and plate tectonic theory.

Paul Somerville is an engineering seismologist now at AECOM (formerly at its predecessor organizations URS and Woodward-Clyde) in Los Angeles. He is also Chief Geoscientist at Risk Frontiers at Macquarie University in Sydney, Australia. He has applied physics-based modeling methods to understand the influence of earthquake source and seismic wave propagation effects on strong ground motion. These include source effects such as rupture directivity and wave propagation effects such as Moho reflections that can give rise to unexpectedly large ground motions, which he experienced “live” in the 1989 Loma Prieta, 1994 Northridge and 1995 Kobe earthquakes. He has served on the Board of Directors for both the SSA and the Earthquake Engineering Research Institute, as manager of the Implementation Interface at the Southern California Earthquake Center, and is currently President of the Australian Earthquake Engineering Society. He has conducted seismic hazard analyses at sites of critical facilities in many parts of the Asia-Pacific region, including Australia, New Zealand and Japan as well as the Americas. He has also been involved in the estimation of earthquake risk for insurers and government agencies in the Asia-Pacific region.

AbstractA new concept of joint hinging having been developed in Japan is presented, which is to be implemented in a new provision in the New AIJ (Architectural Institute of Japan)Standard for Seismic Capacity Calculation. This paper discusses the key issues of the new draft provisions, with background, test data verification, theory and analyses withemphasis on why such introduction of such new concept is inevitable. The design factors affecting the strength of joint hinging failure are discussed for seismic designconsideration. Seismic collapse simulation is made by non-linear time history analysis for moment frames with BC joints failing in the joint hinging, to demonstrate thechallenge of strength degradation and severe pinching hysteretic behavior inherent to the joint hinging. Draft equations yielding the strength of joint hinging of BC joints arealso introduced.BiographyHitoshi Shiohara is a professor in the Department of Architectural Engineering of the University of Tokyo. He received his BS, MS and PhD from the University of Tokyo.

Seismic and Non-Seismic Performance of Prefabricated Element Connections for Accelerated Bridge Construction

Dr. Zachary B. HaberBridge Research Engineer, Professional Service Industries, Inc. FHWA Turner-Fairbank Highway Research Center, Mclean, VA

322 Town Engineering Building

Refreshments will be served

AbstractIn many accelerated bridge construction (ABC) projects, prefabricated bridge elements and systems (PBES) are integral to meeting tightconstruction windows and projects deadlines. The performance of prefabricated bridge systems is highly dependent on the design and detailingof connections between elements. Typically, elements are joined using field-cast grout (or cast-in-place concrete) cast over interlaced reinforcingbars, or into ducts used to embed bars into adjacent elements. The selection of the connection grout and the detailing of the connection canhave a significant impact on both the structural performance and long-term durability of the connection and the system. These aspects canbecome even more important when seismic performance of substructure element needs to be considered. This presentation will cover anumber topics related to the design and performance of prefabricated element connections for ABC projects. The primary focus will be selectionand performance of connection grout materials and reinforcement detailing within the connection region. Prefabricated superstructure andsubstructure systems will be discussed along with considerations for both seismic and non-seismic loading.

Minimum Vertical Reinforcement Requirements for Ductile Earthquake Resistant of RC Walls

322 Town Engineering Building

Refreshments will be served

AbstractReinforced concrete (RC) walls are one of the most commonly used seismic resisting structural systems worldwide. Recent earthquakes in New Zealand and Chile have shownthat lightly reinforced RC walls may only form a limited number of cracks in the plastic hinge region rather than the desired distributed cracking and spread plasticity.Research suggested that the current minimum vertical reinforcement limits in many concrete design standards may be insufficient to ensure well distributed cracking inductile plastic hinge regions. To understand and improve the seismic behavior of lightly RC walls, a combination of large-scale experimental testing and numerical modellingwas used. The first phase of the tests investigated the seismic behavior of RC walls with distributed minimum vertical reinforcement in accordance with current designprovisions. The experimental results confirmed that current minimum vertical reinforcing limits were insufficient to form a large number of secondary cracks and are onlysuitable for walls designed for low ductility demands. A second phase of the tests was conducted to investigate the seismic performance of RC walls with additionalreinforcement at the end regions of the wall, as required by some concrete design standards. Detailed finite element models of lightly RC walls were also developed tounderstand the behavior of the test walls, and to conduct additional analyses to investigate the performance of walls with minimum vertical reinforcement.A summary of the overall research program will be presented with key results used to evaluate the seismic behavior of RC walls designed to the current concrete designstandards in both New Zealand and the US. Recommendations and proposed amendments to current design standards will be presented.
