Modeling And Design Of Rigid Connections Between Columns And Flat Slabs

Abstract

When it comes to the statical calculation and the design of the connection between reinforced concrete flat slabs and columns, the usual practice is to assume a hinged connection. However, in many cases this assumption does not reflect the actual behavior of the connection and a rigid design should be targeted in order to transfer the moments from the slab into the column. This project aims to develop adequate strut-and-tie models in order to find practical solutions on how to transfer the moments from flat slabs into their supporting columns or in other words how to design a rigid slab-column connection. Special emphasis is devoted to solutions for the use of precast columns because the arrangement of the reinforcement is often limited
