The ultimate barrier to prevent contamination of the environment due a release radioactivity from Nuclear Power Plant (NPP) is reinforced concrete (RC) Reactor Building (RB) which encloses nuclear reactor. integrity this main focus Probabilistic Risk Assessment (PRA)-Level 2, in accident scenarios that might affect are modeled terms their consequences and probabilities occurrence. Traditionally...

The seismic safety of existing building stock has become a very critical issue in recent years, mainly earthquake-prone South Europe where most the buildings were designed before enforcement standards. Therefore, concept, development and testing efficient cost-effective retrofitting technologies are nowadays strongly needed, both for society scientific community. This study deals with assessmen...

Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

Setback in elevation of a structure is a special irregularity with considerable effect on its seismic performance. This paper addresses multistory Reinforced Concrete (RC) frame buildings, regular and irregular in elevation. Several multistory Reinforced Concrete Moment Resisting Frames (RCMRFs) with different types of setbacks, as well as the regular frames in elevation, are designed according...
