Assessment of shear capacity of concrete bridge deck slabs using theoretical formulations and FEM analysis

摘要

Reinforced concrete (RC) slabs without shear reinforcement are typical cases of bridge deck slabs. For such structures, shear has been a challenging problem in the assessment based on the current standards. This paper deals with the comparison of the methods for assessment of bridge deck slabs subjected to a concentrated load. Two experimental campaigns were selected as case studies and analysed by the simplified theoretical formulations and linear finite element analysis (LFEA). The differences between analysis methods were discussed regarding one-way shear behaviour of the bridge deck slabs.
