Section 1: Finite Element Analysis (5 Questions, 1 Case-
Based)
Question 1
Which method is used to solve complex structural systems in SAN3701?
A) Trial and error
B) Finite element analysis
C) Graphical analysis
D) Moment distribution
Rationale: Finite element analysis (FEA) discretizes complex structures into smaller elements
for accurate numerical solutions, per 2025 SANS 10160-1 and SAN3701 guidelines.
Question 2
What is the primary purpose of meshing in FEA?
A) Increase computational time
B) Discretize the structure into finite elements
C) Calculate material costs
D) Simplify load application
Rationale: Meshing divides a structure into smaller elements to enable numerical analysis, per
2025 FEA principles and SANS standards.
Question 3
Which FEA software is commonly used for structural analysis per SANS 10160-1?
A) Photoshop
B) SAP2000
C) AutoCAD
D) Microsoft Excel
, 2
Rationale: SAP2000 supports static, dynamic, and nonlinear analyses, adhering to SANS 10160-
1 for structural design, per 2025 guidelines.
Question 4
In FEA, what does a higher mesh density improve?
A) Material strength
B) Solution accuracy
C) Construction speed
D) Cost estimation
Rationale: Higher mesh density increases the number of elements, improving solution accuracy
but requiring more computational resources, per 2025 FEA guidelines.
Question 5 (Case-Based)
Case Study: A steel bridge is analyzed using FEA to assess deflection under a 50 kN load. The
model uses a fine mesh and SANS 10162-1 standards. What is the priority action to ensure
accurate results?
A) Ignore boundary conditions
B) Verify boundary conditions and material properties
C) Use a coarse mesh
D) Exclude dynamic loads
Rationale: Verifying boundary conditions and material properties ensures accurate FEA results,
per SANS 10162-1 and 2025 SAN3701 guidelines.

Based)
Question 6
What is a key limitation of the trial and error method in structural analysis?
A) High accuracy
B) Time-consuming for complex structures
C) Requires no calculations
D) Always converges quickly
Rationale: Trial and error is inefficient for complex structures due to iterative adjustments, per
2025 structural analysis principles.
