Abstract:According to engineering practical problems such as the large workload of modeling and calculation caused by complex shape of trapezoid profiled steel sheets in modern building structures analysis, an orthotropic equivalent model for trapezoid profiled steel sheets was proposed and the calculation formula of relevant elastic constants was deduced. The validity of the proposed model and formula was verified by finite element analysis on typical structures. The results show that the equivalent model can greatly improve the calculation efficiency on the premise of high accuracy.

Keywords:trapezoid profiled steel sheet; equivalent model; orthotropic; plane stress
