1. Seismic Given: A steel building in Los Angeles will be braced by a steel eccentrically braced frames. The structure will be utilized as a communication center that can respond in emergencies. The building height is 155 ft. The mapped spectral response acceleration parameters, S₁ and Ss vaules are 1.30g and 0.50g, respectively. The long-period transition period TL=8 sec. Required: Determine the design base shear of the building using the equivalent lateral force (ELF) procedure. (15 points) II. Wind Given: An office building given as follows: • Basic wind speed: 130 mph . Located in a coastal area with Exposure D • 7-story steel building on a level-ground site . Typical story height of 10 ft, with first story of 12-ft high • Enclosure Classification: Enclosed Lateral force resisting system: Steel Braced Frame Required: For the direction of wind given, determine the external wind pressure on the sidewall and leeward wall, respectively. (15 points) Wind Direction B 60'. A D 72' 1. Seismic Given: A steel building in Los Angeles will be braced by a steel eccentrically braced frames.
