In order to study the mechanical properties of stud connectors in lightweight aggregate concrete (LWAC), finite element software ABAQUS was used establish push test models ordinary and LWAC, respectively. Through parameter analysis 21 models, influence different parameters on shear performance LWAC connector studied. Among them, strength, diameter strength have strong effects. Compared with con...

The shear strength evaluation of reinforced concrete bridge deck slabs by accurate models can indicate reserves and avoid costly operations necessary for the extension their lifetime. This article introduces an approach that extends Critical Shear Displacement Theory model (CSDT) reaching higher levels approximation subjected to concentrated loads close support. A database with 141 tests wide m...
