摘要：
To study the influence of openings on the seismic behavior, two 1/2 scale, two story and one bay models were designed. There are doors on the one side for one model and windows symmetrically for the other. Based on the low-reversed cyclic loading test, the failure characteristics, hysteretic behavior, skeleton curves, bearing capacity, stiffness, energy dissipation and ductility were analyzed. The wall on the one side without openings was damaged along the edge of the beam and column, while the wall on the other side was damaged above the doors and on the corner. The wall between windows and the corner wall were damaged for the model with windows. The bearing capacity on the one side without openings was higher 27% than the other side with doors. The initial, yield and peak stiffness on the one side without openings were higher 7.37%, 30.43%, 35.97% respectively than the other side. The positive and negative ductility of the model with symmetry windows openings were higher 39.55 % and 41.86 % respectively than the other model. The results show that single row of steel bar shear wall is the first seismic fortification line and frame with stability load carrying capacity can function as the second seismic resistant system. For the frame, the design principle of "strong column and weak beam", "strong shear and weak bending", and "strong node" are realized. © 2018, Editorial Board of Journal of Harbin Institute of Technology.
