Column Loss

Experimental Testing and Numerical Analysis of 3D Steel Frame System Under Column Loss

ultistory steel frames are expected to provide resistance to progressive collapse following local damage or failure caused by extreme loading events. Features like ductility and continuity provide more deformation capacity and redistribution of loads so that the structure can bridge over damaged elements. Special measures should be taken to ensure that the connections can withstand the extreme loading […]

Collapse Prevention Design Criteria for Moment Connections in Multi-Story Steel Frames Under Extreme Actions

he paper investigates the role of beam-to-column connections in mitigation the progressive collapse of multi-story steel frame buildings in case of column loss. On this purpose, a set of moment frames with different beam-to-column connections is designed following seismic design criteria for highly dissipative structures to resist seismic actions. Applied Element Method through nonlinear dynamic […]
