一种空心异形柱多高层装配式钢框架-中心支撑体系
摘要：
一种空心异形柱多高层装配式钢框架-中心支撑体系，涉及结构工程技术领域，包括装配式桁架板、装配式法兰柱和中心支撑构件，所述装配式桁架板包括配有角钢腹杆的格构式桁架梁、柱座节点和楼板；所述装配式桁架板在工厂预制，在施工现场将装配式桁架板通过其梁端封板或者柱座节点相互拼接，作为框架结构梁板层；所述的框架结构梁板层通过装配式法兰柱进行上下连接形成多层钢框架结构，所述的装配式法兰柱位于装配式桁架板上的柱座节点上；在所述钢框架结构的基础上，将中心支撑构件连接到框架结构梁板层中的桁架梁或柱底、顶部，作为抗侧力构件；所述的装配式桁架板，装配式法兰柱和中心支撑构件均在工厂预制，施工现场通过螺栓进行装配。
摘要（英）：

A hollow irregular column multi-layer high-rise assembling steel frame-central support system relates to the technical field of structural engineering. The hollow irregular column multi-layer high-rise assembling steel frame-central support system comprises assembling truss plates, assembling flange columns and central support members. Each assembling truss plate comprises a lattice truss beam with an angle steel web member, a column base node and a floor slab. The assembling truss plates are prefabricated in a factory and spliced with one another through beam end sealing plates or the column base nodes on a construction site to form frame structure beam plate layers. The frame structure beam plate layers are connected vertically through the assembling flange columns to form a multi-layer steel frame structure, and the assembling flange columns are arranged on the column base nodes of the assembling truss plates. On the basis of the steel frame structure, the central support members are connected with the bottoms and tops of the truss beams or the columns in the frame structure beam plate layers to be used as lateral load resistance members. The assembling truss plates, the assembling flange columns and the central support members are all prefabricated in the factory and assembled through bolts on the construction site.
