| 摘 要： | 复合刚度方法是一种可以预测Z型截面构件支撑的屋面系统侧向受力的方法。该方法将一系列Z型截面作为单自由度系统分析,并采用刚度公式计算系统中不同的构件对于抵抗侧向位移的贡献。从力学理论中推导出屋面系统所需的抗力。

| Abstract: | The component stiffness method is a method to predict lateral restraint forces in roof systems supported by Z-sections. The method approximates a bay of Z-sections as a single degree of freedom system and uses a stiffness formulation to determine the contribution of the different components in the system to the resistance of lateral movement. The forces generated by the roof system requiring restraint are derived from mechanics. |
