吊车荷载是单层工业厂房设计中很重要的一种活载。在修编新荷载规范(TJ9—74)过程中,对有关吊车荷载的问题曾进行实际调查和测试,作过一定分析工作。现将其中几个方面的问题分别说明如下。一、关于吊车的工作制问题当按吊车荷载进行结构计算时,如选择吊车荷载的动力系数,验算构件的疲劳等,一般需要了解吊车的工作制度。吊车分级本属工艺设计的范围,但土建设计者如能知道
The crane load is a very important live load in the design of single-floor industrial plants. In the process of revising the new load code (TJ9-74), actual surveys and tests were carried out on the problems related to crane loads and some analysis work was done. Here are some of the issues described below. First, on the work of the crane system When calculating the structure by crane load, such as the choice of crane load dynamic coefficient, check the fatigue of components, etc., generally need to understand the crane system. The classification of cranes belongs to the scope of process design, but civil engineering designers can know
