Computer investigation of wind load on a building frame.

Case 1: The columns and girders of the rigid building frame in Figure P5.58 have been

designed initially for vertical load as specified by the building code. Floor beams are

connected to columns by rigid joints. As part of the design, the building frame must be

checked for lateral deflection under the 0.8 kip/ft wind load to ensure that lateral displacement

will not damage the exterior walls attached to the structural frame. If the code requires that

the maximum lateral deflection at the top of the roof not exceed 0.48 in. to prevent damage to

the exterior walls, is the building frame sufficiently stiff to satisfy this requirement?

Case 2: If the bases of the columns at point A and F are attached to the foundations by fixed

supports instead of pin supports, how much is the lateral deflection at joint D reduced?

Case 3: If a pin-connected diagonal bar bracing with a 2 in. × 2 in. square cross section

running from support A to joint E is added, determine the lateral deflection at joint D. Assume

pin supports at joints A and F.

For the columns, I = 640 in. 4 and A = 17.9 in.2; for the girders, I = 800 in. 4 and A = 11.8 in. 2 ;

for the diagonal brace, A = 4 in. 2 . Use E = 29,000 ksi.
