Strengthening of Horizontal Bracing on Progressive Collapse Resistance of Multistory Steel Moment Frame
In this study, the contribution of horizontal bracing to the resistance of a steel moment frame against progressive collapse was investigated using the alternate path method. Nonlinear dynamic analyses of two frame models with and without horizontal braces were carried out in various cases. The dynamic nonlinear analytical results indicated that compared with the model without braces, the displacements and rotation angles in the model with horizontal braces were much smaller because of the horizontal tie provided by the horizontal braces at the top story. It was observed that the horizontal braces could transfer the vertical loads originally carried by the removed column to the adjacent columns. Also, the layout of the horizontal braces was an effective means to enhance the resistance of the steel moment frame.
