1. The structure shown below has a special moment resisting moment frame for a lateral force resisting system. It is carrying the load of emergency generator. The soil profile is Site Class D. Based on the USGS map, spectral response acceleration parameters, Ss and S1 are 2.3g and 0.8g respectively. The weight of rigid floor is 15 kips. The emergency generator weighing 35 kips is located on the center of the rigid floor. (20 points) 1) Find the period of...

All work must be shown. You are in charge of retrofitting an existing building. The columns and girders are in place, and you have to design the beams. The building is high end (deflection limited to live load limit of L/480 and a dead load+ live load requirement of L/240). Design the most economical beam size (using conservative calculations) if the unfactored live load is 100 psf and the unfactored dead load (including beam weight) is 80 psf 30 Points...

Q1. A two-storey building is braced against the horizontal load in both directions. The column for the second storey is shown in Fig. Q1. The floor-to-floor height for each storey is 3.5 m. Each beam connected to the column is 5 m long. The sizes of beam A and beam B are 250 x 400 and 300 x 500 mm respectively. The design axial load is 2000 kN. The design end moments about the major axis, which cause the column...
