Current and Tentative Seismic Design Provisions for Buildings: Preliminary Comparisons.
Abstract
This report compares current and tentative seismic design provisions for two types of buildings: (1) Letterman Army Hospital, an existing 10-story, reinforced concrete building located in the Presidio of San Francisco, CA, whose design was based upon the 1964 Uniform Building Code (UBC), and (2) a three-story, ductile moment resistant steel frame building located in a region of high seismicity and designed as an essential building. The comparisons for Letterman Hospital include the magnitude and distribution of the seismic story shears and lateral deflections for the 1964 UBC, the 1975 Structural Engineers Association of California (SEAOC) provisions the 1978 Applied Technology Council's tentative design provisions (ATC-3) the TM 5-809-10 Appendix proposed design provisions, Agababian Associates' (AA) two-dimensional time history modal analysis, U.S. Army Construction Engineering Research Laboratory's (CERL) three-dimensional response spectrum modal analysis and PMB Systems Engineering Incorporated's (PMB) three-dimensional response spectrum modal analysis. The comparisons for the three-story, ductile moment resistant steel frame building include the seismic design forces, story shears, lateral deflections, member sizes, and frame weights for the transverse direction if the building when designed in accordance with the 1975 SEAOC provisions, the 1978 ATC-3 equivalent lateral force procedure, the 1978 ATC-3 modal analysis procedure, and the TM 5-809-10 Appendix proposed provisions.
