Abstract
ABSTRACT
The object of this paper is to investigate the aseismic capacity of the steel rigid frame with truss type open web members by Pseudo-elastic method. Firstly, the moment curvature curve of member section have been established. Secondly, the structure will be analyzed linearly by adopting SAP2000 software, also the member force are carried out. After structure behavior into nonlinear state keep using Pseudo-elastic method, and transfer the energy which exceeding the elastic range into plastic energy. Then the nonlinear response of the frame can be simulated out. Finally, ultimate lateral force, ultimate drift, ductility and collapsed ground acceleration can be determined which are the index of estimating the structure aseismic capacity.
The studies are carried out comparition for aseismic capacities between steel frames with open web members and frames with H-shape members. The study results show that steel rigid frame with open web members may be adopted in long span multiple-story under well controlled in material capacity under construction and well design in sub member arrangement for improving aseismic capacity.
