Seismic Design Decision Analysis. Inelastic Design of Building Frames to Resist Earthquakes

摘要

Typical apartment house structures designed according to Uniform Building Code standards were subjected to earthquake motions and analyzed. The main objective was to evaluate the ductility ratios and interstory displacements which result when the buildings are subjected to a severe earthquake. Three sets of building designs were studied: six story concrete moment resisting frame (CMRF) buildings; eleven story concrete moment resisting frame buildings; and eleven story steel moment resisting frame buildings (SMRF). Within each of these sets there was one design for each earthquake zone, 0 to 3 (zone 0 and 1 are the same) and a design for a 'super' zone (4), which had a zone factor twice as large as that in zone 3. These buildings were subjected to an artificially generated earthquake with a maximum acceleration of 0.27g. This earthquake was generated to match the response spectrum developed for the Boston, Massachusetts area.
