钢框架预应力支撑结构拉索截面面积设计方法
|
摘要
为了研究钢框架预应力支撑结构体系中拉索截面面积的取值方法,从理论上对钢框架预应力支撑结构体系的抗侧刚度进行分析,推导出结构体系的抗侧刚度计算公式.钢框架预应力支撑结构体系的抗侧刚度不仅与构件的几何属性和材料属性有关,而且与预应力支撑与水平面的夹角有关,结构体系的抗侧刚度随着层间位移的增大而增大.基于钢框架预应力支撑结构体系抗侧刚度的计算公式,推导出了预应力拉索截面面积设计公式,提出了一种预应力拉索截面面积设计方法,并通过算例验证了提出的设计方法和设计公式的可行性,得到的钢框架预应力支撑结构,可以保证结构体系在设计的外荷载作用下,满足设计对于结构层间位移的要求.
To study the design method of cable sectional area of prestress-braced steel frame structure system,lateral stiffness of this structure system was analyzed theoretically in this paper. Formula of lateral stiffness of this structure was derived. The formula shows that lateral stiffness of this structure is related to not only the sectional properties and material properties of members,but also angle between cable and horizontal plane. Lateral stiffness increases with the increase of story drift gradually. Based on the formula of lateral stiffness,design method and formula of cable sectional area of this structure was proposed. Practicability of this design method and formula was proved through an example,the results concluded that the prestress-braced steel frame structure which is designed by using this formula and method can make sure that the story drift of structure meets code requirements under designed external loads.
