Details of H-Beam-to-RHS Column Joints with through Diaphragm for Progressive Collapse Prevention
A partial damage caused by an abnormal load could trigger progressive collapse of high rise buildings which may lead to fatal consequences. To meliorate structural robustness, two types of joint with improved connection details—modified bolted connection and retrofitted bolt-weld connection and their corresponding design methods are proposed on the basis of the conventional RHS column joint with through diaphragm. The numerical results indicate that both the modified bolted connection and the retrofitted bolt-weld connection can enhance the vertical deformation capacity of the beam-column assemblages before the force transmission failure at the bottom of connection region, which is conductive to the development of catenary action by axial force in the beams. For that reason, the beam-column assemblages can provide greater vertical carrying capacity and the two improved connection details can be used in designing and transforming structures against progressive collapse.
