Precast Steel-Reinforced Concrete (PSRC) structural frame systems for moment-resisting, comprised of Prefabricated Steel (S) girders and Reinforced Cement (RCC) columns. This system has the advantage inherent stiffness damping during a seismic event. PSRC’s moment-resisting is also known its construction efficiency, lightweight, low cost. Earlier investigations have shown PSRC helpful in design...

In order to investigate the structural performance of CLT-S hybrid structure with several types connections improve hysteresis behavior, experiments frame were conducted. new connections, reduced section parts inserted steel plate restrained for buckling provide improved behavior against cyclic axial forces due bending moment in CLT panels. From experiment result, it was found that hysteretic p...

The main aim of the present study is to optimize steel moment frames in the framework of performance-based design and to assess the seismic collapse capacity of the optimal structures. In the first phase of this study, four well-known metaheuristic algorithms are employed to achieve the optimization task. In the second phase, the seismic collapse safety of the obtained optimal designs is evalua...

In and post a fire event, an accurate and real-time evaluation and monitoring of a structure’s performance can assist firefighters for efficient survivor rescuing, which significantly improve the fire rescuing safety both for fire fighters and the trapped survivors. However, due to the lack of durable sensors, the structural performance of steel structures in fire conditions is challenging to b...

The evolution of plastic deformation and damage in steel frame buildings caused by seismic action is simulated based on a modified damage model. This model combines nonlinear isotropic and kinematic hardening criteria with a damage evolution law expressed in terms of plastic displacement. A nine-story steel frame is chosen as a reference structure, and a nonlinear damage analysis is performed u...
