COLUMN ANALYSIS

INTRODUCTION TO THE ASSIGNMENT In this project, we were required to analyse a two or three-storey bungalow not exceeding 300 sqm, which includes ground floor plan, first floor plan and roof plan, then produce the structural floor plan, load distribution plan, tributary plan and foundation plan.

We are then required to carry out structural analysis report for the chosen bungalow by choosing the structural elements position that include two beams, beam to beam connection, beam to column connection. Two columns, intermediate column and edge column.

The house I chosen is call Khanh House which located at Vietnam. The floor area of the house is around 28o sqm.

STRUCTURAL ANALYSIS REPORT Self weight of materials 1.

Reinforced concrete floor slab Dimension : 0.15 (Thickness) Density of reinforced concrete : 24 kN/m³ Self weight of slab : 0.15 x 24 kN/m³ = 3.6 kN/m²
