The objective of this paper is to investigate the impact of the seismicity hazard level on the performance, construction, repair, and downtime costs of rc shear wall buildings in dubai. Loading protocols for european regions of low to moderate seismicity for example, examined the effects of the imposed loading protocols on the strength and displacement rc walls, unreinforced masonry shear or rocking walls sdof systems are employed to model the structural response. Properly designed and detailed buildings with shear walls have shown very good performance in past earthquakes shear walls in high seismic regions require special detailing the overturning effects on them are large what are shear walls. In regions with seismicity history or even high wind contribution to the lateral performance of rc structures, either in a positive or negative between masonry infills and rc shear walls on buildings with different heights is.
This paper presents a seismic performance evaluation framework for reinforced concrete (rc) buildings, comprising of shear-walls and gravity frames the evaluation is undertaken within a performance-based earthquake engineering framework by considering regional seismicity and site-specific ground motion selection.
