摘要
介绍了单箱多室变宽箱梁活载内力计算原理及在设计过程中的简化计算方法。以实桥为例,将各种简化计算方法的计算值与空间有限单元法计算值进行比较,探讨设计方法的可行性。最后推荐在设计过程中应采用的较合理的计算方法。
A review of live-load inner force calculation theory of mono-box with multi-cells non-uniform width box-beam and simplified calculation method in design procedure are given in this paper. Depend on case history, the check of calculation results between many methods and space finite-element method is carried out, for discussing the feasibility of design method. At last, the paper recommends the relatively appropriation calculation method for design.
