Reinforced concrete (RC) core walls are commonly used to provide buildings with lateral and torsional resistance against the actions of wind earthquakes. In low-to-moderate seismic regions, it is not unusual find a single peripheral wall that alone should resist these actions, where (rotational) twist cannot be neglected. It has previously been difficult have confidence in simulating axial-flex...

recently, scientists developed the seismic rehabilitation of structures and their points of view were changed from strength to the performance of structures. nonlinear static procedure (nsp) or pushover analysis is a new method that is chosen for its speed and simplicity in calculations. “seismic rehabilitation code” & fema356 considered this method. result of this analysis is a target displace...

The stiffness of masonry infill walls is commonly neglected in design practice Reinforced Concrete (RC) structures. In fact, the wall may significantly influence seismic performance and dynamic behavior RC buildings. this research, to structural a three-story frame investigated. addition, possible application friction-based support also studied. Full 3D non-linear time history analysis conducte...

Despite achieving consensus and having current knowledge on the behaviour contribution of masonry infill walls, there remain unresolved issues regarding their nonlinear as a method for strengthening existing reinforced concrete (RC) frames with effective modifications, primarily infills interconnection frames. The challenge safely economically designing competent walls is to utilise stiffening ...

The performance of buildings subjected to earthquake loads has shown that asymmetric structures are caused more extensive damages in comparison with symmetric structures. Hence, the seismic performance of asymmetric structures should be assessed due to future random earthquakes. Reliability-based seismic assessment as one of the tools in performance-based earthquake engineering has been introdu...
