Steel-concrete composite plate girders subject to combined shear and bending

摘要

Details of an experimental investigation on steel-con rete composite plate girders subject to the combined action of shear and bending are presentdd in this paper. Six composite plat; girders have been tested to failure in order to study their ultimate load behaviour. Two differeiv web-depth to thickness (d/t) ratios and two different moment/shear ratios have been considered Attention is focused on the variation in tension field action in web panels due lo composiu action between the steel girder and concrete slab. Extensive strain measurements have bees made on the web panels in order to obtain a detailed picture of tension field action. Tht ultimate load carrying capacity and the tension field width of composite plate girders are fount? to increase significantly compared to the bare steel girders.
