Energy Absorbtion Of Suspended Zipper Braced Frames

This paper introduces an energy absorbtion by the elements of suspended zipper braced frames and compares the amount of energy absorbed by the elements of inverted v braced frames.Three zipper-braced models were designed to carry the same masses as the 3-, 9-, 20-story buildings with moment-resisting frames. Pushover analyses of the models were performed by Perform 3D v5.0.0 software to estimate the overstrength, inelastic strength and deformation capacities for the entire structures and assess the sequence of yielding and buckling in the members. The distribution of energy through the elements of the structure demonstrates the efficiency of the zipper struts in achieving uniform damage over the height of the structure .
