Evaluation of the response of BFP and WFP connections under the blast loading

one of the most important structural members that greatly affects the overall performance of the structure is the beam-to-column connection. Undesirable performance and failure of these connections can lead to local failure in the first step, and in the next step,a progressive collapse in the struct...
