12.6 Evaluate and compare seismic design requirements and base shear force for several buildings in different cities across the United States. Seismic Acceleration Parameters for each site is given on the map below. The buildings' general description, dimensions and weight is shown on the next page table. For each case determine the following: a) Total seismic weight of the building b) Building vibration period using Equation 1 on the previous page; c) Response modification Factor from ASCE Table 12.2-1 d) Seismic base shear using the equations below Seismic Base Shear In accordance ASCE-7 code, buildings must be designed to withstand lateral forces that are generated during a severe earthquake. The minimum required design force is given by a series of equations as shown below. Equivalent Base Shear, Seismic response coefficient, In these equations: V= C, W Spil Cs TR C₂ < SD31 R Sp₁ & Sps are Seismic Acceleration Parameters that depend on building site and soil type, I is Importance Factor that depends on the building use and function, R is Response Modification Factor that depends on the building framing system, and W is the Effective Seismic Weight of the building.
