Loading Analysis of Edge Members in SPSW with Opening

Abstract:

Taking a group of SPSW with openings with or without edge members as example, this paper states the importance of edge members in view of initial stiffness, ultimate bearing capacity and ductility. First, FEM analysis is carried out to study the reasonable stiffness-range and it is found out when the inertia moments ratio varies from 6 to 8, edge members not only provide adequate anchorage, but also resist loads directly with main frame. Then, an unified calculation model called USMO is proposed, whose key point is to add inversed compression bars with stiffness to tension zone to simulate the increase of ultimate bearing capacity, leaving shearing part same to USM.
