方钢管和型钢混凝土(STRC和STSRC)短柱是普通的RC和/或SRC短柱，其侧向配筋大多为薄壁钢管的形式。本文通过六根钢管混凝土短柱和六根钢管混凝土短柱在恒定轴压和反复水平荷载作用下的试验，研究了两种结构的抗震性能。主要参数为轴压比和纵筋配筋状态。建立了非线性三维有限元模型来模拟试件的单调行为和强度。利用所建立的有限元模型对额外假定试件的性能和强度进行了预测。根据试验和分析结果，提出了STRC和/或STSRC短柱抗剪强度的设计计算公式。
The square tubed reinforced and steel reinforced concrete (STRC and STSRC) short columns are ordinary RC and/or SRC short columns where most of the lateral reinforcement is in the form of thin-walled steel tubes. In this study, six specimens of STRC and STSRC short columns were experimentally tested under constant axial compression and cyclic lateral load to investigate the seismic performance of both kinds of structure. The main parameters were the axial load ratio and status of longitudinal reinforcement. Nonlinear 3D finite element model was developed to simulate the monotonic behavior and strength of tested specimens. The behavior and strength of extra assumed specimens were predicted using the developed FEM model. Depending on the test and analysis results, a design formula was proposed to predict the shear strength of STRC and/or STSRC short columns.
