Tools > General Section Designer Design > Pushover Analysis > Define Hinge Properties

1. Improvements in Pushover Analysis

1.1 Export Moment-Curvature Idealized Model from midas GTS to Gen Moment-Curvature(M-φ Lumped) type hinge properties can be automatically generated based

on the idealized moment-curvature curve obtained in midas GSD. For P-M and P-M-M interaction type hinges, a number of Moment-Curvature curves with

various axial forces can be imported at once. “GSD Imported Type” skeleton curve is newly added to simulate the reduction of flexural

capacity

separately plotted in Moment Curvature Curve of GSD.

Hinge length ratio can be defined by the user for the region which reaches plastic moment for Moment-Curvature (M-Ф Lumped) hinge definition . The user can select whether pushover hinges will be assigned to the center of the hinge length or

I & j-end of an element.

2.1 Improvements in Multi-linear Type Inelastic Hinge Properties

Perfect plastic primary curve of multi–linear type hysteresis models can be defined in Inelastic Hinge Properties. In the old version, in order to simulate the perfect plastic behavior, the user needed to enter the very small increment of force. Compression-only and Tension-only primary curve can be defined. Scale factor for displacement and force in multi-linear type hysteresis model is added.

Compressive Strength

Creep/Shrinkage and Compressive Strength can be considered as per both AS/RTA5100.5-2011 and AS3600-2009. After performing construction stage analysis, midas Gen provides the following member

forces separately for each construction stage: Dead Load, Tendon Primary, Tendon Secondary, Creep Primary, Creep

Secondary, Shrinkage Primary, Shrinkage Secondary, Summation

1. Improvement in data export to midas FEA and midas GTS

File > Export > MXT File (for FEA/GTS)

Data import using mxt file.

In the old version, only node and element information were transferred. In the new version, expended information such as properties, boundary conditions, loads, and analysis control information are supported.

Note. Cross-sections data that are not supported in midas FEA are imported as user-type section. Cable elements are imported as truss elements.

2. Export in IFC file format

File > Export > IFC File

Import in Revit Structure

Midas Gen model data can be exported into IFC (*.ifc) format file. This format will be useful for exporting structural analysis model into BIM tools. It includes only geometry information with various type of sections excepting for composite section. It does not support loads, boundaries, and analysis control information.

3. Improvements in Local Direction Force Sum

Results > Local Direction Force Sum

Local Direction Force Sum

Plate + Beam Model

All Plate Model

When bridge decks and girders are modeled using combination of beam and plate elements, resultant forces can be calculated in Local Direction Force Sum. In the old version, the resultant forces were obtained only for the case that model is composed of plate elements only or solid elements only. In the new version, resultant forces can be obtained for the bridges composed of “Beam(deck) + Beam(girder)” and “Plate(deck) + Beam(girder)”.

Local direction force sum can be obtained in any construction stages. In the old version, Local Direction Force Sum was activated only in Post CS.

“By Member” option is added to check beam diagram by members, not by elements. When member is assigned using Member Assignment function, “By Member” option will be activated and beam forces by members can be viewed in the model view and table.

Absolute maximum, Min/Max, All(I, Mid, J) options are applicable with By Member option.
