摘要
加劲梁的结构型式,大体土分钢梁和混凝土梁两种钢梁,主梁类型有钢主梁、混凝土主梁、钢及混凝土结合梁、钢及混凝土混合梁等多种型式的加劲梁,应结合桥梁的实际情况,包括静力、动力特性,施工运输条件、抗风要求、抗震要求、后期养护以及结构设计等多种因素,经综合比选确定。
Types of stiffening girder structure are by and large divided into steel girder or concrete girder. It has the main girder of multiple type, for instance, the steel main girder, concrete main girder, girder combined by steel with concrete and girder mixed by steel with concrete etc. Its structure type should be determined in the light of bridge reality, including the static, dynamic characteristics, transportation conditions for construction, requirements for wind - resistance, anti - seismic requirements, maintenance at later stage as well as structure design and so on.
