摘要
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 presents results of the experimental investi gation of a23-storey steel-RC combined structure model with the scale of 1:2 0.This modelconsists of a reinforced concrete core and the external steel frame.The elasticbehaviour under the action of a 6-point loading system and the elastic-plasticalbehaviour under cyclic loading are investigated. The experimental result showsthat the combined construction is a potential structure form for earthquake-resistance. Also it is verified that the reliable linkage between steel andreinforced concrete elements is critical to achieve satisfactory structural behaviour.
