钢管混凝土拱桥拱肋刚度取值

The steel-concrete pipe arch bridge rib rigid degree value chosen

由于我国目前尚无钢管混凝土拱桥的设计规范,通过对目前钢管混凝土拱肋刚度计算方法的比较分析,认为采用《CECS28:90》犤1犦的方法较合理,供设计参考。

There is not a design rule about steel-concrete pipe arch in our country.Through the analysis of calculation method on the rigid degree of steel-concrete pipe arch rib,《CECS 28:90》is reasonably adopted.
