In recent years, for the influence of all kinds natural disasters, transmission tower’s collapsing or line’s damage presents a growing trend. The assembly stress in towers is often ignored when people analyze accidents. To study actual stress, production process should be summarized and simulated. Find out method to calculate simulate by using finite element analysis software. Trussed beam hybr...

Load carrying capacity of flat double-layer space structures majorly depends on the structures' imperfections. Imperfections in initial curvature, length, and residual stress of members are all innately random and can affect the load-bearing capacity of the members and consequently that of the structure. The double-layer space trusses are susceptible to progressive collapse due to sudden buckli...
