Slip Phenomenon

In ancient China timber building earthquake damage records, often about "column small feet slip", scholars in ancient timber buildings for the seismic performance study, also thought that "column small feet slip" is one of the reasons for the ancient building in the earthquake Could be survived. This article through to column small feet slip phenomenon, to lead to column small feet slip condition were analyzed, and "column small feet slip" seismic effect evaluation, is to the ancient timber aseismic performance research achievements added.

In recent years, wall panels have been more and more used in the steel residential houses. A series of investigations on the seismic performance of the steel frame with composite panels have been carried out. According to the connection types between the steel frames and the panels, the structural system can be divided into two kinds: steel frames with hanging composite panels and steel frame infilled with composite panels. Results of all researchers revealed that the composite panels could effectively improve the lateral stiffness and bearing capacity of the steel frames, at the same time could enhance the energy dissipation capacity. Morever, in this paper, the relevant research results of connections between the steel frame and composite panels obtained are compared and discussed. This review provides helpful directions to those who are already engaged in composite panels used in the steel residential houses, and points out the simplified method needed to promote safe and economic use of composite panels.

Shear Bearing Capacity

Four constructional columns with concrete porous brick walls were constructed for low cyclic loading test. The damage on the characteristics and strength of the wall, hysteresis curve, ductility and other seismic performance were analyzed. Setting constructional columns in the wall at both ends increase the ultimate strength and improve its deformation, ductility and other properties. Meanwhile the height-wide-ratio of wall, axial pressure and other factors on the shear bearing capacity on the wall have been studied. Based on the shear capacity formula of wall in the Structural Seismic Design Code, considering the contribution of the constructional columns on the shear strength, according to the results, the shear capacity formula of constructional columns with concrete brick walls is presented.

The Impact

Side-strengthened reinforced concrete or precast prestressed concrete beam for inadequate seismic performance is proposed in this paper. The factors are simulated by ABAQUS software for the impact of seismic performance, which are difference of material strength grade, initial load and the order of prestressing and pretightening. The strengthening technology can improve the seismic performance of side-strengthened beam. The meterials with different strength grades which used for beams give full play to their role. The initial load has little effect on the seismic performance. The way of prestressing after pretightening plays a favorable effect for the seismic performance. The simulation results can accurately reflect the impact of these factors on the side-strengthened beam.
