CFVR9175 - Shell shear reinforcement design according to ACI 318 19
Shell shear reinforcement design according to ACI 318 19.
The model is made up of two square shell elements of 1.0m x 1.0m. The nodes of one side are completely restrained and one of the nodes between both element has its vertical movement restrained (perpendicular to the shells).
There is no shear reinforcement in the slab.
The applied loads is a pressure of 3 kg/cm2 on one of the elements.
The reinforcement design code is the ACI 318 19.
