Study of Computer Modeling Formulation and Special Analytical Procedures for Earthquake Response of Multistory Buildings

摘要

The results of correlative analytical studies performed on five multistory buildings located in seismically active regions of the United States are presented. Several models of each building are formulated to assess the influence of various structural and nonstructural modeling aspects on dynamic properties and seismic response. Aspects such as two-dimensional versus three-dimensional frame modeling, rigid joint zone effects, participation of secondary framing systems, nonstructural slab-girder interaction, infill block walls, and mass modeling variations are considered. Effects of different modeling approaches on analytical results are evaluated and the relative importance of various modeling reinforcements is noted.
