摘要
现代建筑中由于建筑功能的要求,大跨度结构已越来越普遍,在实际工程应用中,若大跨度梁与柱子铰接,梁受弯较大,截面也需加大,不够经济合理;若大跨度梁与柱子刚接,梁对柱子产生的巨大水平力易导致柱子失稳,针对这种情况,本文提出一种桁架与钢管柱先铰后刚的连接方式,并采用有限元软件Abaqus分析其可行性。
Due to the functional requirements,large-span structure becomes more common in modem architecture. In the practical engineering applications,if the large span beam and the column are hinged,beam would be bent larger and the cross section need to be enlarged,which causes the inefficiency in economic cost, If the large span beam and the column are rigid connected,the huge horizontal force caused by beam pressure would lead to instable of the column. Considering tbc situation,this paper proposed a method of bingmg the truss and steel column first,then connecting rigidly at a later stage. Feasibility of the proposed method is further analyzed by the finite element software Abaqus.
