肋式剪力连接件在组合结构中得到越来越多的关注。特别是在桥梁结构中，与传统的复合材料剪力连接件（如大头钉）相比，肋剪力连接件具有许多优点。为了描述循环荷载下肋剪力连接件的承载性能，必须考虑剪力连接件循环荷载导致的滑移连续增加。后者导致相对位移沿着组合节点的增长，从而导致先前刚性剪切连接的退化。这种效应导致复合材料伙伴之间的内力重新排列，从而改变结构的承载性能和承载能力。本文介绍并分析了关于复合材料互连退化的两次循环单推出试验（sPOT）和一次全尺寸梁试验的实验研究结果。足尺梁试验中研究的剪力连接件承受的荷载历史与sPOT中连接件的荷载历史相当。结果给出了深入了解剪切连接的退化的影响，如前所述，在sPOT，对组合梁的整体承载性能。
Rib shear connectors are gaining increasingly attention in the field of composite constructions. Especially in bridge constructions, rib shear connectors offer many advantages compared to conventional composite shear connectors such as headed studs. In order to describe the load‐bearing behaviour of rib shear connectors under cyclic loading, the successively increasing slip resulting from the cyclic loading of the shear connectors must be taken into account. The latter leads to the growth of the relative displacements along the composite joint and thus, to the degradation of the previously rigid shear connection. This effect leads to rearrangements of internal forces between the composite partners through which the load bearing behaviour and load bearing capacity of the structure alter. In this article results of experimental investigations on two cyclic single Push‐Out‐Tests (sPOT) and one full‐scale girder test regarding the degradation of the composite interconnection are presented and analysed. The investigated shear connectors in the full‐scale girder test are subjected to a comparable load history to that of the connectors in the sPOT. The results give insight into the effects of the degradation of the shear connection, as previously seen in sPOT, on the overall load bearing behaviour of composite girders.
