Wall‐diaphragm interactions in seismic response of building systems I: Parametric models and elastic response

The objective of this paper is to study the elastic seismic response simplified building models that include considerations vertical lateral force resisting system (walls) and horizontal (floor diaphragms) through parametric study. assumption rigid diaphragms often used in design buildings; however, research suggests diaphragm may influence fundamental period response. In paper, a model presented for single multi-story buildings utilizing two degrees freedom per story system, example, walls, one degree floor diaphragm. number stories, stiffness walls diaphragm(s), mass distribution between are varied represent large range potential compositions. Eigen analyses indicate wall interact when at similar periods resulting elongation overall period. Response time-history where it shown demands both diaphragm(s) dependent on relative mass-distribution these systems. companion “Wall-Diaphragm Interactions Seismic Building System II: Inelastic Design” extending nonlinear including different levels assumed inelasticity
