摘要:
工业建筑中的设备往往体量大,重量大,可能对主体结构的动力特性产生明显的影响,从而影响结构的抗震性能。本文以某包含五组大型风管设备的屈曲约束支撑钢筋混凝土框架结构工业厂房为研究对象,分析结构-设备耦联体系在罕遇地震作用下的地震反应分析。为此,采用各向异性的壳单元模拟风管保温板,并与钢结构骨架一起形成风管的有限元模型。为考察风管对主体结构地震反应的影响,比较了仅有主体结构、将风管设备按等效质量考虑的主体结构和结构-设备耦联体系等三个模型的最大地震反应。分析结果表明,对于本文算例,在线弹性和弹塑性分析中,结构-设备相互作用都会对主体结构的最大反应产生明显的影响,但是影响规律比较复杂,尚有待进一步深入分析。
Abstract:
Large scale and heavy equipment in industrial buildings may have considerable effect on the dynamic properties of the structure, and thus may influence the seismic performance of the building. The seismic response of a buckling restrained reinforced concrete building which hosts five units of large scale air ducts is analyzed by a model that considers the structure-equipment interaction. An orthotropic elastic material is developed to use in shell elements for the simulation of the composite panels in the air ducts. Three models of different approaches in modelling the equipment are established and the corresponding results are compared to investigate the effects of structure-equipment interaction. The results show that the structure-equipment interaction has considerable effects on the peak responses of the primary structure in both linear elastic and nonlinear analyses, whereas the influence is complicated and deserves further investigation.
