Structural Assessment of Truss and Concrete Structures

ENGIN5302 Modelling & Simulation EXERCISE 01 Project 2019/05
Objective
To perform the structural assessment of two different structures as two separate tasks as below:
1) Task-I : Deformation and Strength assessment of Truss Structure
2) Task-II : Deformation and Strength assessment of Concrete Structure
Problem Statement
Task-I Truss Structure
The truss shown in Figure 1 is subjected to distributed load along the top left face and point loads at various
intervals. Have performed a finite element analysis of the truss using Abaqus CAE 6.14

Assumptions and FE Approach
 All the members have a square cross section with sides b = 300 mm. See Figure-2
 The Young's modulus of the material used in the construction of the truss is E = 210 GPa. See
Figure-3 for Material Property configuration in Abaqus.

Geometry
 As mentioned in the problem statement the same geometry is created in Abaqus CAE. Firstly
the keypoints are plotted through coordinates and connected with lines in the sketch as shown
in Figure-4. The wire Model is assigned the section profile as discussed earlier.

Material
As mentioned in the problem statement, structural steel Material is used. The Material Properties are as below:
Density (kg/m3) 7850
Young's Modulus (GPa) 210
Poisson's Ratio 0.3
