Rc Shear Wall

Reinforced concrete shear walls play an important role in improving seismic performance of building structures. In this paper, a new type of RC shear wall with concealed bracing is proposed and investigated. Four 1:3 scale medium-height specimens were designed and a detailed experimental investigation carried out. The load-carrying capacity, stiffness, ductility, hysteretic behavior and energy dissipation of the shear wall are discussed. The failure mechanism was revealed by the experiments. It is found that in comparison with a normal shear wall, the seismic performance of a shear wall can be significantly improved by adding concealed bracing within the wall panel. Finally, a mechanical model of the shear wall is proposed and formulae for calculating load-carrying capacity developed. It is shown that the theoretical results agree well with those from experiments.

Reinforced concrete (RC) shear wall component is a very important lateral force-resisting member which is widely used in China. Its seismic behavior has a great impact on the seismic performance of the overall structure. Damage of some RC shear wall structures under the earthquake is caused by the damage of shear wall components, So shear wall components are an essential seismic members. However, the test datum are not enough to study the performance of RC shear wall components, Therefore, Finite element simulation of RC shear wall components is performed by software ABAQUS in the paper. Through comparing with the finite element simulation and the test of load - displacement skeleton curve, failure mode and steel bar strain, the result shows that the finite element simulation can more accurately simulate the situation of the test, verifying the finite element simulation is the most important research tool besides test.

Rc Shear Wall

Indonesia is one of the countries in the earthquake region. Therefore, it is necessary to build earthquake-resistant buildings to reduce the risk of material and life losses. Reinforced Concrete (RC) shear walls is one of effective structure element to resist earthquake forces. Applying RC shear wall can effectively reduce the displacement and story-drift of the structure. This research aims to study the effect of shear wall location in symmetric medium-rise building due to seismic loading. The symmetric medium rise-building is analyzed for earthquake force by considering two types of structural system. i.e. Frame system and Dual system. First model is open frame structural system and other three models are dual type structural system. The frame with shear walls at core and centrally placed at exterior frames showed significant reduction more than 80% lateral displacement at the top of structure.
