Seismic performance under low cyclic experimental study on the six of constructional column- core column composite reinforcement concrete block masnory wall is preasented in this paper, considering the height-width ratio, window hole and without window hole, the setting of the horizontal reinforcing steel bar in the walls. Failure process and failure pattern, hysteresis characteristics, bearing capacity, ductility, skeleton curves, the viscous damping coefficient, stiffness and steel strain change the properties are analyzed, respectivily. Test results shown that this kind of composite reinforced concrete block masnory system has better seismic performance.

The use of concrete aggregate from earthquake damaged building to make blocks which needed for post-disaster reconstruction has brought the social, environmental, economic and other benefits, at the same time respond to the basic state policy of low carbon energy saving. At home and abroad currently focused on the materials properties of recycled aggregate and recycled concrete block basic physical mechanics to study, but research for the material block wall structure performance is less, the research for the wall shear strength and anti-seismic performance of this kind of wall is of great significance. Based on the recycled concrete aggregate from Mianyang, Sichuan where is disaster area to make three hole hollow block wall (no reinforcement) to perform low cycle experiment, collecting four samples, and achieved anti-seismic indicators such as the hysteresis curves, skeleton curves of recycled concrete block wall, analyzes the influence of the axial pressure, the loading method on seismic performance of block wall.

According to the analysis of a six-story reinforced concrete masonry building model with the methods of nonlinear time history analysis, the seismic performance of structure has been studied in this paper. The interstory shear-deformation and stiffness of linear elastic model is established. The availability of the analysis model, hysteretic model and relevant parameters adopted and the computation program developed are verified. The longitudinal deformation of structure is bigger than the lateral deformation under different earthquake waves, from this it can be showed that longitudinal seismic performance is smaller than lateral wall; for seven-story concrete block building with core-and tie-columns, the requirement of the seismic fortification intensity can be met. The analysis of this paper provides a reference for reinforced concrete block buildings.
