Structural evaluation of wall slab connection, incorporating steel fibre subjected to lateral cyclic loading / Ahmed Abdulrazzaq Nasser

Most reinforced concrete failures occur not because of any inadequacies in analysis of the structure or in design of the members but because of inadequate attention to the detailing of reinforcement. In the wall slab system, the lateral displacement imposed on the wall when subjected to lateral cyc...
