BUILDING STRUCTURES
In this course, we learned about the building structures and the forces applied to them.
Project 1 involves the study of truss. Truss is a structure built up of three or more members which are normally considered being pinned and hinged at the joints. Load applied to the truss is trnasmitted to joint so that each individual members are in either pure tension or compression.
Objectives of Project
The objectives of this project are as follows
* To develop student’s understanding of tension and compressive strength of construction materials
* To develop student’s understanding of force distribution in a truss
* To design a perfect truss bridge which fulfils the following criterias:
o High level of aesthetic value
o Minimal construction material
Learning Outcomes
* Able to evaluate, explore and improve attributes of construction materials
* Explore and apply understanding of load distribution in a truss
* Able to evaluate and identify tension and compression members in a truss structure
* Explore different arrangement of members in a truss structure
In a group, we were required to design and construct a fettucini bridge of 750mm clear span and maximum weight of 200g. These requirements are to be met, or else it may result in reduction of grade. The bridge will be then tested to fail.
Other than aesthetic value, the design of the bridge must be of high efficiency, i.e. using the least material to sustain the higher load. The efficiency of the bridge is given as following;
In order to achieve higher efficiency, we need to analyse and evaluate each of the following items.
* Material strength
o By adopting appropriate method, determine the strength of fettucini, i.e. tension and compression strength
o By knowing the strength of fettucini, we will be able to determine which members to be strengthened
* Structural analysis of the truss
o Perform detailed structural analysis of the truss
o Identify critical members
o Strengthened the critical members if necessary
Project 2 Extension of a R.C. Bungalow
The project is an integrated component where it involves structural theory, force calculation and basic structural proposal. This project is designed to allow the demonstration of knowledge and understanding of building structure.
Objectives of Project The objectives of this project are as follows:
To introduce the basic process of building structures design process to the students.
To enable the students to have a holistic experience including Concept and Structure Layout Design, Building Structure Engineering Considerations, Structure Members Sizing and Calculations, Final Report and Presentation. Learning Outcomes
Produce a complete documentation on structural system of a case study
Explore and understand the concept of structural analysis
Identification of structural components Recognize, Execute and implement basic procedures of building structure design
Produce a structural proposal
In an initial group of 6, we had to obtain floor plans of a maximum 3 storeys bungalow, preferably 2 storeys. From a study of the floor plans, we had to produce the structural plans which include foundation plan, ground plan, first floor plan and roof plan.
For the second part of this project, we divided ourselves into group of 2. Along with my friend Lee Qin Ni, we proposed an extension work to the bungalow that meet the following criteria,
1. Propose an extension work to the bungalow that meet the following criteria,
a. The area of extension should not exceed 30% of the existing floor area (max 100m2 each floor)
b. The extension should be sideway. c. The extension should be of two storeys
2. Frame the extension by using appropriate structural members i.e. columns, beams, slabs, or trusses.
3. Identify and quantify the load acting on the structure.
4. Each member is required to: a. analysis minimum 6 beams (each beam must subject to different types of load, i.e. UDL from one or more than one slabs, beam with point load(s) or combination of UDL and PL) b. analysis minimum 3 columns (from roof to foundation level)
5. Prepare foundation plan, ground floor plan, first floor plan and roof plan for the extension.
 First Floor |  Structural First Floor |  Ground Floor |
|---|---|---|

Analysis of 6 beams and 3 columns. Down below is my analysis and calculations.
