摘　　要：本文介绍了六榀钢筋混凝土支撑框架模型（两榀为普通支撑框架，另四榀为消能支撑框架）在低周反复荷载作用下的工作性能和试验结果；编制了非线性程序、对试验模型进行了计算分析，计算结果和试验实测值符合较好；另外还计算了两榀足尺消能支撑框架结构，研究不同的消能器滑移荷载对结构抗震能力的影响，结果表明消能支撑框架结构具有良好、稳定的抗震性能。In this paper, six reinforced concrete frame models, including two common braced frame models and four energy-dissipation braced frame models, have been tested under cyclic load reversals for comparison. In addition, a computer program of nonlinear statics analysis is designed and the seismic behaviors of the six frame models are analyzed with this program. In order to investigate the influence of the slip-load on the seismic behavior of structures, two en- ergy-dissipation braced full scale frames are also analyzd. It is shown that the energy-dissipation braced frame has excellent seismic behavior than tbe common structures.
