Low-damage steel frame structure and prefabricating and assembling method
The invention discloses a low-damage steel frame structure and a prefabrication assembly method. The low-damage steel frame structure comprises a foundation, a first frame column, a second frame column, a frame beam, a floor slab, a beam end connecting piece and a column bottom connecting piece. The first frame columns are installed on a foundation through column bottom connecting pieces, the second frame columns are arranged above the first frame columns, the number of the second frame columns is set according to the number of layers of the structure, and connecting points of the first frame columns and the second frame columns and connecting points of every two adjacent second frame columns are located at inflection points of all layers of the structure. The frame beams are fixedly connected with the second frame columns on the two sides through beam end connecting pieces. Floors are arranged on the upper end faces of the frame beams; according to the invention, the beam-column joint and the column bottom joint can reach a bending-shearing separated stress mechanism, and plastic hinge areas at the beam end and the column bottom are prolonged, so that the damage to the beam-column joint and the column bottom joint is reduced, the residual deformation of the steel frame structure is reduced, and the shock resistance toughness of the structure is improved; all structural components can be prefabricated and produced in factories and assembled on site, and construction is convenient and fast.
本发明公开了一种低损伤钢框架结构及预制装配方法，结构包括：基础、第一框架柱、第二框架柱、框架梁、楼板、梁端连接件和柱底连接件；第一框架柱通过柱底连接件安装在基础上，第二框架柱设置在第一框架柱上方，根据结构层数设置第二框架柱数量，第一框架柱和第二框架柱的连接点，及相邻两个第二框架柱的连接点位于结构各层的反弯点位置；框架梁通过梁端连接件与两侧的第二框架柱固定连接；楼板设置在框架梁上端面；本发明可使梁柱节点和柱底节点达到弯剪分离的受力机制，使梁端和柱底的塑性铰区域延长，从而降低梁柱节点和柱底节点的损伤，减小钢框架结构的残余变形，提高结构的抗震韧性；各结构部件可在工厂预制生产，现场装配，施工便捷。
