EFFECT OF STAIRS ON SEISMIC PERFORMANCE OF REINFORCED CONCRETE BUILDINGS
Reem Nady Abo-Serie EL-Nady Helal;
Abstract
Key Words:
Staircase element, fundamental period, linear analysis, seismic force
Summary:
Staircase elements in buildings are usually designed for gravity loads only while their
contribution in resisting seismic loads is neglected. However, stairs increase the overall
stiffness of structures and may attract considerable seismic forces leading to their
damage and failure and thus losing their important role in life loss prevention during
and after earthquakes. This thesis studies and evaluates the influence of stairs in seismic
performance of multi‐story building structures according to Egyptian code of practice.
Response spectrum and equivalent static load methods are used for the analysis.
Buildings are modelled as a three dimensional finite element model using SAP2000
program. The building response behavior is considered linear elastic. The design
parameters considered in this thesis includes stair location and orientation, slab
structural system, building height.
