在役大跨石拱桥极限承载力的影响因素
Influencing factors of ultimate bearing capacity of inservice long span stone arch bridge
摘要
Abstract
sing double nonlinear finite element method, the effects of several aspects -load distribution, temperature influence, initial imperfection and structural damage and so on, the ultimate bearing capacity of a long - span arch were studied. The results show that load types, loading arrangement, initial structure geometric imperfection and damage have great influence on the ultimate bearing capacity of existing large - span bridge.关键词
