ANALYSIS AND EXPERIMENTS ON THE PLASTIC LIMIT MOMENTS OF ELBOWS WITH/WITHOUT LOCAL THINNED AREA

摘要：

The plastic limit load of elbows under in-plane closing bending moments is discussed in this paper. In this research finite element analysis (FEA) and experiments have been used. The results of FEA show that the limit load of elbows under in-plane bending moments increases with the increasing wall thickness and increasing bend factor of elbows. By data fitting of FEA, an empirical formula of the limit load for elbows with/without local thinned area in extrados has been obtained. These results have been validated by the experiments.
