Unformatted text preview: Assume that there are no nearby faults. Calculate the design base shear and story forces. Compare with the Arleta location. Problem 6-3 (4 points) A 4’ high, 5’ wide, 8’ long, 3000-lb HVAC fan unit supported at its corners is to be installed on the roof of the replacement fire station building. Because of the living space below, the unit might need to be installed on vibration isolation springs. Determine the IBC2006-required horizontal component force Fp for the two cases (with and without isolation springs). State the load combination equations that should be used to determine the anchorage forces (just give the equations, don’t do the calcs). Note: Design examples from the FEMA 451 CD I gave you will be helpful. Look at the Steel and Concrete design examples for help with selection of dead loads and live loads for Problem 6-1. Look at the Nonstructural design examples (Chapter 13) for help with Problem 6-3....
