Evaluation of seismic performance of X bracing systems equipped with flexural yielding dampers [PDF]
Journal of Structural and Construction Engineering, 2017 The X-bracing system is one of the lateral loads bearing system. In X-bracing system’s elements, axial plastic hinges (compressive or tensile) will be formed instead of flexural hinges which are not capable to absorb high energy.
