Prestressed steel reinforced concrete frame applied to outer-jacketing structure and its restoring force model based on IDARC

Abstract

A new style of frame structure made up of encased H-shape steel prestressed concrete composite beams and angle-steel concrete columns with 4 or 8 angle-steels is put forward and joint constructions of the frame are given in detail. This frame is fit for reconstructing the existing building using outer-jacketing structures for storyadding. On the basis of analyzing application of PARK trilinear restoring force model in IDARC analysis software, recommended restoring force models of beams and columns of prestressed steel reinforced concrete frame based on IDARC in seismic response analysis are given as well as the method regarding frame joint as rigid region. It provides basis for elastic-plastic seismic response analysis of prestressed steel reinforced concrete frame applied to outer-jacketing structure for story-adding. © Maxwell Scientific Organization, 2013.
