Abstract The main aim of this investigation was to study the flexural strength and drift ratio simply supported rectangular RC hollow beams (with a longitudinal square hole) subjected gradually increased symmetrically applied one-point load. Each beam had 300 mm2 900 mm2-area square, position center hole 80 mm from top. cross-section beam, amount steel, stirrups kept constant. deflection these ...

Response modification factor (R factor) is one of the seismic design parameters to be considered in evaluating the performance of buildings during strong motions. This paper has tried to evaluate the response modification factor of concrete coupled shear wall structures with various length/depth ratios of spandrel beams. The effect of diagonal reinforcement of spandrel beam was also evaluated o...

During the earthquake phase, dampers were used to dissipate energy as well stop Deformation of Structure. We may reduce buckling and failure columns beams by increasing stability frame with help dampers. earthquakes, high-rise buildings are destroyed, there is significant deformation. shaking reinforcement cement concrete structures during an using various types in this analysis determine suita...

There is a possibility of increasing structural damage in the sequential earthquake compared to main according past earthquakes. This study investigates effects seismic sequence on behavior and increased response reinforced concrete frames (RCF) with/without steel plate shear walls (SPSW). Four systems 4, 8, 12, 24 story, which represent low-, mid-, high-rise structures, are designed subjected ...

Dampers can reduce structural response under dynamic loads. Since dampers are costly, the design of structures equipped with dampers should make their application economically justifiable. Among the effective cost reduction factors is optimal damper placement. Hence, this study intended to find the optimal viscous damper placement using efficient optimization methods. Taking into account the no...

Abstract While Dhaka, the capital city of Bangladesh, adapts to more and high-rise buildings skyscrapers, concerns remain about their design efficiency ability withstand shear loads from seismic movements. In this study, several orientations placements walls in a regular G +15 story reinforced concrete building were assessed observe nature structure subjected earthquake by adopting Equivalent S...
