- 通过以18m跨MMR-238型波纹拱为对象,采用ABAQUS有限元软件,对不同矢跨比下,支座不等高对波纹拱在不同竖向荷载工况下承载力的影响进行研究。A 18mspan MMR-238 ACSR is taken as a research object. For ACSR with different ratio of rise to span,the influence of unequal altitude support to the bearing capacity under different vertical load is studied,by using ABAQUS finite element software.
