サンドイッチ型複合床版の疲労耐久性に関する一考察

抄録

Recently, the continuous composite girder with steel-concrete composite slab has been attracting attention because of economical efficiency, serviceability and load carrying capacity. Authors have developed steel-concrete sandwich slab. Sandwich slab is composed of upper steel plates, lower steel plates, steel shapes and filled concrete. By applying the sandwich slab to continuous composite girder, the design of superstructure becomes more rational. This paper describes results of wheel running tests carried out to check the durability of sandwich slab.
