9层(带转换层)钢筋混凝土异形柱框架结构模型振动台试验研究

Study on Shaking Table Test of a 9-storey RC Frame Model with Specially Shaped Columns and Transfer Storey

异形柱框架结构具有室内无突出棱角、增加使用面积等优点,当配合轻质墙体材料使用时,还可节约耕地、减轻建筑物自重。但还存在着对其整体抗震能力的怀疑。为此,结合实际工程进行了9层(带转换层)的钢筋混凝土异形柱框架结构模型的振动台试验。对试验结果进行分析并提出一些设计建议。本文认为:经精心设计的异形柱框架结构能满足7度地震区的抗震设防要求。

The specially shaped column frame structure system is used widely for its merits, such as the none prominent angularities indoors so that the usable area can be enlarged. In combination with employing lightweight materials, it can save tilth and lighten building weight. In spite of its so many merits, yet there still exists the suspicion of its aseismic capability.A shaking table test of a 9 storey RC frame model with transfer storey has been carried out. The test results are analyzed with some design suggestions presented. In this article, it is concluded that this structure can be used in the region of earthquake intensity 7.
