摘要
该文结合工程实例,提出了各腹板长度相差较大时不规则预应力混凝土连续刚构桥的简化计算方法,即将空间效应明显的不规则刚构桥简化为平面杆系结构进行计算,并通过空间有限元进行论证分析,结果表明该简化计算方法有效可行,可满足工程设计的安全性及精度要求。
Combined with the engineering practical example, the article puts forward the simplifying calculation method of the irregular pre-stressed concrete continuous rigid frame bridge when the lengths of various webs are more different, that is, the obvious space effects of the irregular rigid frame bridge are simplifies to the plane member system structure for calculation, and demonstrated and analyzed through the space finite element. The result makes clearly that this simplifying calculation method is effective and feasible, which is able to meet the safety and accuracy requirement of the engineering design.
