本文介绍了在建研院结构所进行的一个二十三层钢，混凝土混合结构模型的试验结果。该模型由一个钢筋混凝土芯筒与外钢框架组成，模型缩比为１：２０。进行了六点单调加载弹性阶段试验及二点、一点反复加载弹塑性性能试验。试验结果表明：该种结构形式是一种良好的抗震结构形式，可应用于８度地震区。同时，试验还表明，良好的钢－混凝土构件连接是保证钢－混凝土混合结构抗震性能的关键。
This paper introduces the test results of a twenty-three-layer steel and concrete mixed structure model carried out in the institute’s structure. The model consists of a reinforced concrete core barrel and an outer steel frame with a ratio of 1:20. Six-point monotonic loading elastic stage tests and two-point, one-point repeated loading elastoplastic performance tests were carried out. The test results show that this kind of structural form is a good form of seismic structure and can be applied to the 8 degree earthquake area. At the same time, the test also showed that good steel-concrete structural connection is the key to ensure the seismic performance of steel-concrete hybrid structures.
