Abstract A computational study was conducted to examine the seismic performance of steel moment‐resisting frames (MRFs) provided with chevron concentric braces. Such systems are widely used for buildings in Japan. Nonlinear finite‐element‐method models were validated against data and observations from previously tested chevron‐braced MRF specimens. The conduct a parametric understand how cyclic...

experimental tests were performed to study the seismic behavior and performance ofmodified steel chevron braced frame systems, which incorporate a vertical slotted connection(vsc) detail between the top of the braces and the floor beam above. the vsc detail isintended to prevent vertical load transfer to the beam and limit brace forces to thecompressive resistance of the members. full-scale qua...

In this paper, the authors summarize the results of a parametric study devoted to evaluate the seismic behavior of low to medium rise regular special moment-resisting steel frames with hysteretic energy dissipation devices mounted on chevron steel bracing. For that purpose, 270 different building models were designed considering typical story heights and bay widths used in Mexican practice. The...

zipper braced frames are an innovative bracing system for steel structures. conventional inverted-v-braced frames exhibit a design problem arising from the unbalanced vertical force generated by the lower story braces when one of them buckles. this adverse effect can be mitigated by adding zipper columns or vertical members connecting the intersection points of the braces above the first floor....

In the recent past, several research studies have highlighted that prescriptions reported in codes for design of structures with concentric braces chevron configuration are often not effective preventing yielding or buckling non-dissipative members and ensuring collapse mechanisms characterised by uniform damage braces. To investigate reasons these deficiencies, this paper seismic response conc...

The design of steel chevron-braced frames as per Eurocode 8 is based on the idea that only braces should buckle and yield during ground motions, while other members remain elastic. elastic braced also allowed. However, in both cases, seismic performance frame may be compromised because premature yielding/buckling columns. This paper proposes an alternative procedure promotes yielding beams addi...

Building structures are subject to displacement under the influence of forces resulting from earthquake. The most common method of controlling such displacements in steel structures, which are usually of lateral type, is the use of braces. Depending on designing requirements and feasibility, braces are available in various forms. Configuration of bracing systems is generally of concentric or ec...
