Modelling and Comparison of Plastic Performance in Ten Types of New Steel Braces under Pushover Analysis [PDF]
Computational Engineering and Physical Modeling, 2023 Safe design of the structure in earthquake increases the ability to absorb and dissipate energy by the bracing system. Also, one of the new methods to reduce earthquakes is the formation of plastic hinges in the flexible members of the structure.

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.

A plastic collapse method for evaluating rotation capacity of full-restrained steel moment connections [PDF]
Theoretical and Applied Mechanics, 2008 An analytical method to model failure of steel beam plastic hinges due to local buckling and low-cycle fatigue is proposed herein. This method is based on the plastic collapse mechanism approach and a yield-line plastic hinge (YLPH) model whose geometry ...
