Abstract: In this paper,the studies on irregular simply-supported skew girder are continued,and more formulae used for calculation reactions and internal forces under commonly occurring loading are derived.In order to understand the behaviour of the reaction of the irregular skew girders several tgpes of tgpical skew garders are discussed.Lastly,the calculation method of the simply-supported skew girder is advanced in which the redistribution of internal forces are considered,and an example is given.

Key words: simply-supported skew girder, skew bridges, reactions, calculation method, the redidtribution of internal forces

摘要： 在现代桥梁、房屋以及其它结构中,由于结构外形复杂多变,平面形状为梯形的斜支承简支梁已成为常见的构件型式。本文以导出的梯形斜交简支梁的反力计算公式为基础,对四种特殊斜梁的反力特性进行了讨论。据此可对梯形斜交简支梁的反力特性有较清晰的认识。随后,本文提出了考虑内力重分布的计算方法,并给出了算例。
