| 摘 要： | 钢框架-内填冷弯薄壁型钢组合墙体结构体系可适用于多、高层建筑结构。利用SAP2000有限元软件分析了此体系在不同高宽比和钢框架截面尺寸下的承载力、侧移刚度、剪力分配情况。结果表明,钢框架、组合墙体可协同作用;组合墙体与钢框架之间剪力分配符合刚度分配原则;框架-内填冷弯薄壁型钢组合墙体抗侧刚度近似等于纯钢框架与组合墙体抗侧刚度之和。同时给出了钢框架、组合墙体协同工作的剪力分配计算简化公式,可用于此结构体系的抗剪设计。

| Abstract: | The steel frame in-filled cold-formed thin-walled steel composed wall can be used to multi story building.The load-carrying capacity,lateral stiffness,and the distribution of shearing force of this system are analyzed under different height-width ratio of wall and sections of steel frame using SAP2000.The results show that steel frame can work together with composed,lateral shear between composed wall and steel frame wall can be obtained based on the stiffness of the composed wall and steel frame,and The lateral stiffness of the steel frame in-filled cold-formed thin-walled steel composed wall is approximate to the total lateral stiffness of steel frame and composed wall.Finally,the calculated formula of the shear distribution for steel frame in-filled cold-formed thin-walled steel composed wall is put forward and can be used to design this kind of building. |
