Elastio-plastic dynamic analyses of 5 reinforced concrete frame-core wall structures with different structural characteristics were carried out under several sets of ground motions. The earthquake total input energy of the structure under ground motion, and the regularity of the total input energy between hysteretic energy and damping energy were discussed; the distribution of hysteretic energy among shear wall, coupling beams and frames were studied, as well as the distribution of hysteretic energy along different stories. The results show that the hysteretic energy is increased with the peak ground acceleration. The earthquake records with different spectrum characteristics have a great influence on hysteretic energy. Although the total hysteretic energy among different structural members are steady, the distribution of hysteretic energy among shear wall, coupling beams and frames may vary significantly. It is found that the bottom portion of shear walls and coupling beams in middle floors are the predominant energy dissipated area.

Seismic Vibrations

The reinforced concrete structures, not designed for seismic conditions, amid the past earthquakes have shown us the significance of assessment of the seismic limit state of the current structures. During seismic vibrations, every structure encountered seismic loads. Seismic vibrations in high rise building structure subjects horizontal and torsional deflections which consequently develop extensive reactions in the buildings. Subsequently, horizontal stiffness can produce firmness in the high rise structures and it resists all the horizontal and torsional movements of the building. Therefore, bracing and shear wall are the mainstream strategies for reinforcing the structures against their poor seismic behaviours. It is seen before that shear wall gives higher horizontal firmness to the structure when coupled with bracing however it will be another finding that in building model, which location is most suitable for shear wall and bracing to get better horizontal stability. In this study, a 15 story residential reinforced concrete building is assessed and analyzed using building code ACI 318-14 for bracing and shear wall placed at several different locations of the building model. The technique used for analysis is Equivalent Static Method by utilizing a design tool, finite element software named ETABS. The significant parameters examined are lateral displacement, base shear, story drift, and overturning moment.

Shrinkage Effect

In order to discuss the effect of different concrete strength on the seismic behavior of the L-shape steel reinforced concrete (SRC) short-pier shear wall , this article analyze three L-shape steel reinforced concrete short-pier shear walls of different concrete strength with the numerical simulation software ABAQUS, revealing the effects of concrete strength on the walls seismic behavior. The results of the study show that the concrete strength obviously influence the seismic performance. With the concrete strength grade rise, the bearing capacity of the shear wall becomes large, the ductility becomes low, the pinch shrinkage effect of the hysteresis loop becomes more obvious.
