摘要:
基于生命线工程的抗震设防要求,开展了通信机房走线架悬吊杆垂直布置、梯形布置和混合布置下吊挂系统的抗侧性能研究;采用理论方法推导了3种布置方式下吊挂系统的抗侧刚度,并采用有限元分析软件ANSYS加以验证;对3种布置方式下吊挂系统的抗侧刚度进行比较分析。研究结果表明:悬吊杆垂直布置和梯形布置时走线架吊挂系统抗侧刚度小,主要由重力刚度决定;悬吊杆混合布置时吊挂系统具有较大的初始抗侧刚度;悬吊杆混合布置时吊挂系统满足“小震不坏,大震不倒”的抗震设防要求,是一种比较合理、高效的布置方式。
Abstract:
According to the requirements for seismic resistance of lifeline engineering, research on the lateral performance of cable tray suspension systems in communication workshop with vertical, trapezoidal and composite suspender layout was conducted. The lateral stiffness of suspension systems with the three kinds of suspender layouts was derived by theoretical methods and the formulas were verified by finite element analysis software ANSYS, respectively. Then comparison was carried out. The study results show that the lateral stiffness of cable tray suspension systems with vertical and trapezoidal suspender layout is small, which is mainly determined by the gravity stiffness. The initial stiffness against lateral displacement of suspension system with composite suspender layout is much larger. Suspension system satisfies the seismic fortification requirement of “no damage in small earthquake and no collapsing in strong earthquake” in the case of composite suspender layout, which is verified as a more reasonable and efficient layout.
