Construction Technology & structures

• Focuses on non-

domestic construction

methods for commercial

and high-rise buildings

• Includes the study of

composite materials

2. What are the constraints

associated with high-rise

construction?

1. How are tall

buildings designed to

overcome the lateral

forces?

Construction & structures module is broad but in the

main, it relates to understanding the design, behaviour

and therefore methods of assemblies associated with

steel, concrete and composite structures of both

medium and large scale nature.

Define appropriate structural framing methods

• What are the design considerations?– Load, height, wind, gravity and Seismic loading

• What are the construction assembly

methods?– Composite, rigid, flexible & rigid construction

Why Study Construction Technology

and Structures?

Why are some materials more appropriate to

high-rise construction and not low-rise

commercial buildings?

Disparity is resolved by defining composite

frame design and assembly methods

Key aims

To foster analytical thinking and

understanding of the principles that

determine the behaviour of structural

elements and the main factors that

dictate their design.

The module encourages both

deductive (logical links) leading to

inductive thinking of how building

materials in non-domestic buildings

are selected and formed into

structural elements and which

combine to create functional

structures of varying scales.

Key Learning Outcomes

1. Distinguish between

structural and non-

structural elements in

terms of functional and

performance

expectations!

Shear

cores

2. Demonstrate an understanding of structural behaviour of key

building elements and how they are detailed and assembled to

ensure improved structural performance

Notice the positioning of columns

3. Identify the factors that are critical to structural behaviour of medium

to large scale buildings! Such factors in tandem, will dictate the detailing

and rules of assembly for all primary and secondary interconnections be

it structural or non structural. The aim is to ensure that regardless of

scale, buildings should by design, fulfil the ultimate purpose for which

they are intended: workable and liveable spaces and in prime

locations dictate the ecomass of a city.

• Defining appropriate framing systems

• Disparity is resolved by defining a

composite frame and assembly methods

resit the exam. The resit mark obtained will be capped at 40%.

e.g. at resit student gets 85%, this mark will still be reduced (capped) to 40%.

Thus a final module mark of 65% is recorded and awarded [ie. (45% for cwk

+ 20% due to capped resit mark of 40%].

presence of uncontrolled fill and a high

concentration of sulfates in the soft clay silts. Upon

examining the proposal in detail, it becomes apparent

to you that the in-house foundation design may not

be adequate and warrants further consideration.

Task 1.

•With reference to the proposed foundation shown in

the brief (Figure 2 & 3), identify the inadequacies that

may be a source of concern to the structural

robustness of the foundations for the 6 storey building.

•Using clearly and well annotated drawings suggest

suitable solutions to enhance the original foundations.

Assignment briefTask 2:

•The construction of the Loading bay (Figure 2) is to allow for

loading/unloading of goods by heavy articulated trucks. Using a

scale of 1:50, produce Hand/CAD drawn elevations at the

following points within the loading bay:

Please note: for this task all elevations/sections must be

based on the details as shown in Figure 2. Do not assume

alternative details beyond the in-house design brief provided

herewith.

Task 2:

a. Front elevation at ‘FE’ taken at mid-point of the loading bay

wing and allowing 1000mm as the projection of the head-wall

either side of the loading bay walls. Your drawing should be fully

annotated, labelled and well described with as much technical

detail as deemed necessary for the onsite project team.

Assignment brief

Task 2: (continued)

b. A longitudinal cross section through

the loading bay taken at ‘LS’; assuming

a total length of 6.1m from the loading

bay end wings. The detail should

floor to the loading bay, including

ground beams.

(Detail 2 drawn on a single side A3 as

maximum) (22 marks)

Coursework submission form

Handing in instructions (please adhere to the following requirements or risk losing marks)

This module requires you to submit your coursework via

Turnitin, as well as a comb-bound folder.

Submitting online: via Turnitin

• In Turnitin you can revise, re-check and resubmit your work right up to

24hrs before the submission date and time.

• Only a single file submission containing all the three tasks will be possible

to upload (in other words each task cannot be submitted separately. Todo

this efficiently, Task 1 and 3 must be word processed on single-sided A4.

Then your drawings should be scanned and inserted after the

corresponding or respective tasks. It is only then that you should upload

all the written tasks and drawings in one goal under one file name.

Rules for submission

• Please ensure that any written tasks comply within the page limit

indicated against each respective task. i.e. each written task must be

word processed, on single-sided A4; the font face should be in ‘Times

New Roman’, font size 12; the spacing between lines of text and

paragraphs is 1.5.

• The Bibliography should be produced on 2 single-sided A4 maximum;

this should be appended at the back of the folder and has to comply

with the same font and spacing as specified above.

• Your name and student number should be on every page (easily done if

you include this in the header or footer).

Please refer to the MODULE GUIDE for a more detailed assessment

outline. The content here is only a summary of all the notes relating to

the assessment brief.
