1. Frame-Tube Problem:

Analyze the rectangular tubular structure shown in the following Figure with customized FE software available and calculate axial forces, shear and moment in the column (critical) at level 1 and deflection at top and furnish necessary comparison and comments.

2. Shear Wall-Frame Problem

Figure below shows the reinforced concrete shear wall frame structure located in Dhaka. Analyze with available FE software and determine the bending moment, shear force, axial force in the wall A, Wall B and critical column at level 1 and deflection at top when the building is subjected to a uniform wind load of 50 psf parallel to the short direction. Comment if wall B of one side is not placed.

Lateral Load = 50 psf

50 stories @ 10

Columns = 1620

Beams = 1236

No. of stories = 30

Story height = 3.5 m

Beam size = 0.30.6 m

Column size = 0.60.6 m

Wall thickness = 0.3 m

E = 2.0107 kN/m2

= 0.15

3. Bracing Inclusion:

Same problem as No. 2 without any shear wall and with following:

Case A: With steel bracing all around with assumed size

Case B: Without Steel bracing

Compare and comment discussing Case A and Case B. You are free to increase column sizes if required to run the analysis linearly.

Assume necessary data if not given. For making fruitful and challenging discussions you may extend or deviate the problem statement but in this case you should have appropriate logic. For each problem Analysis should be linear and deflection at top should be checked with allowable limit.
