摘要
本文以某拟建多层厂房工程为例,介绍了钢筋混凝土空腹夹层板楼盖盒式结构新体系的组成。采用MIDAS/Gen有限元分析软件建立有限元模型,将钢筋混凝土空间网格盒式结构厂房与常规钢筋混凝土框架结构厂房进行对比,从结构的自振周期、楼层位移、层间位移角、经济技术指标等方面进行对比分析。分析结果表明,盒式结构新体系在空间整体性、空间刚度和经济效益方面均优于常规结构。
New RC cassette structure with open-web sandwich plate floor was introduced based on a proposed multi-storey factory building in Guiyang. Finite element models of RC spatial grid cassette structure and conven- tional RC frame structure were built by using MIDAS/Gen Software. The two kinds of structures were compared by such properties as natural vibration period, storey deflection, storey drift angle and econo-technical norm, etc. Analysis results show that the integrity, spatial stiffness and economic benefits of the new structure system are better than that of the conventional structures.
