چکیده مقاله
Inverted v braced frames are typical braced frame configurations which with increase of lateral loads the compressive braces buckle and plastic hinges form in the braces Shear capacity of frame decrease as a result of compression braces' buckling To overcome these limitations of chevron braced frames zipper braced frames have been suggested Zipper columns are vertical members connecting the mid points of the beams above the first floor In order to investigate the seismic behavior of zipper braced frames 3, 6, 9 and 12 story zipper braced frames was designed and modeled in ABAQUS and nonlinear time history analyses were conducted As a consequence, the results showed that zipper columns help to improve the seismic performance by uniform damage distribution over the height of building
