带竖缝砌体填充墙钢筋混凝土框架结构抗震性能试验研究
Experimental study on seismic behavior of slitted masonry in-filled reinforced concrete frame structure
摘要
Abstract
In order to investigate the effects of slitted masonry in-fill walls on the seismic behavior of the reinforced concrete frame structure, comparison tests of three frame structures with slit masonry in-fill wall, one frame structures with masonry in-fill wall and one bare frame structure subjected to low cycle reversed load were carried out. The damage characteristics, load-displacement hysteretic curves, skeleton curves, displacement ductility, rigidity degradation, bearing capacity degradation and energy dissipation of specimens were analyzed. The test results show that the masonry in-fill wall enhances the lateral stiffness and bearing capacity of frame structures and contributes to the hysteretie energ~ ~I slructure. The cumulative energy dissipation capacity of masonry in-fill wall frames is significantly better than that of I,are frame. Due to the vertical slit with a certain width between the in-fill wall and the frame column, the wall-column interaction can be reduced, and the cracking load of in-fill walls and the beams, columns of main frame are increased. The horizontal bearing capacity of the specimens is between that of bare frame and that of whole in-fill wall frames, while the displacement ductility and energy dissipation capacity of specimens are greatly improved. The ultimate inter-story drift ratio of the specimen is basically the same that of the bare frame. The specimens have good ductility and energy dissipation capacity.关键词
