The document provides details on the structural design and analysis of a two-storey bungalow project. It includes the architectural plans, structural plans, load distribution diagrams, tributary area diagrams, and structural analysis calculations for key structural elements like beams and columns. Specifically, it analyzes the forces, loads, and bending moments on Ground Floor Beam D/1-1A and C1-E/1A, as well as Column C/4. The analysis determines the ultimate load values and reaction forces to properly design and size the structural components.

1.0 Introduction to assignment
Structural analysis is crucial in determining the appropriate sizes of structural
components such as beams, columns and footings, which involves quantification of the
total load transferred to the components. As architects, we need to know the process
of load transfer and distribution in a building as well as the process of structural
analysis to understand the basic works of the engineer. With that, hopefully architects
would produce better designs with more consideration towards the structural
components. This assignment is designed to gauge the students’ knowledge and
understanding of the main topics in this module; slab, beams and columns, as it
integrates structural theory, force calculation and basic structural proposal.
Objectives:
1. To introduce the basic process of structural design of a two-storey bungalow.
2. To gain a holistic structural design experience including the basic concepts in
structural design, engineering considerations in building structure,
quantification of loads and stresses, as well as the estimation of the sizes of
structural members.
