Comparison of the performance of the structure with a Chevron braced frame with Zipper braced frame

In Chevron braced frame, due to the buckling of brace on one story, an unbalanced force arrives perpendicularly in the middle of the beam, causing the destroy of the floor and, at the end, causes structural failure. On the lower floor, due to the buckling of the compression member, an unbalanced ver...
