On the premise of maintaining certain vertical bearing capacity, the frame structure dissipates seismic energy by elastic-plastic deformation in elastic-plastic stage of earthquake action. Using lightweight concrete in structure not only can reduce the its dead weight, decrease the earthquake power; also meet the concrete strength, stiffness and elastic modulus requirements of important structure, so as to improve its energy dissipation capacity. This paper researched the effect of concrete materials, including or such as C60 high strength Lightweight concrete (HSLC), high strength concrete (HSC) and high strength Light weight aggregate concrete (HSLAC), on the seismic behavior of RC column under horizontal low cyclic loading, respectively and the match relationship between concrete and steel reinforcement cage was analyzed.

Light Weight Aggregate

The density of concrete less than that of nominal concrete achieved by any means is referred as Light weight concrete. Circulated air through Concrete, Light Weight Aggregate Concrete, Foamed Concrete are different types of Light weight concrete. In this research study, the density of the concrete has been reduced by replacing the coarse aggregate by the pumice stone as light weight coarse aggregate. The major advantage of this study is to reduce the risk of seismic damages of the structure by reducing the self weight of the structure. The decrease in dead load of structure because of the utilization of LWC additionally brings about reduction in the cross segment of other auxiliary individuals such as beam, column and foundation. The pumice stones have huge number of voids and have moderately higher warm protection than the ostensible aggregates. The objective of this research is to obtain light weight concrete having low unit weight and an optimum compressive strength. The Nominal concrete and the light weight concrete is prepared and the tests were led to decide the mechanical properties and compressive quality, its flexural capacity in beams

This article presents a staggered and out-of-plane connection between concrete-filled steel tubular column and reinforced concrete beam (SOC-TCB). SOC-TCB is taken from the basement roof joint of Suning center, which is a height of 341.85 m in China. In this joint system, the H-shaped steel brackets are welded with steel tube to transfer shear and moment. Moreover, the reinforcing bars are interrupted by steel tube and lapped with steel bracket. To investigate the seismic behavior of SOC-TCB, four types of SOC-TCBs were tested under reversal cyclic loading. The differences between specimens were staggered height and out-of-plane angle. Seismic performance was evaluated based on hysteretic behavior, failure mode, shear deformation, rotational deformation, and energy dissipation. The results showed that the shear deformation of joints was extremely small and the plastic hinges were formed at reinforced concrete beams. Due to insufficient anchorage length of longitudinal bars, anchoring failure was found in the reinforced concrete beams. However, SOC-TCB showed better seismic behavior as long as sufficient anchorage of longitudinal bars was ensured.
