部分柱頂滑移鋼筋混凝土框剪結(jié)構(gòu)模型試驗(yàn)研究
[Abstract]:The seismic simulation shaking table tests of partial column top slip reinforced concrete frame shear structure model (model B) and traditional frame shear structure model (model A) are carried out. The two models are both three-story, two-span and two-bay, and the plane layout is the same. The geometric similarity ratio is 1: 10, and the second layer is the structural weak layer. In addition, the mechanical properties of the friction bearing were tested, and the range of friction coefficient was determined. It is found that: 1) the average friction coefficient of the friction bearing of PTFE stainless steel mirror plate without lubricating oil is about 0.070 脳 0.095, and the average friction coefficient of this kind of friction bearing with lubricating oil is about 0.014 脳 0.018; 2) under the action of different peak seismic waves, the maximum displacement angle, the maximum vertex relative displacement, the maximum absolute acceleration of the weak layer and the maximum absolute acceleration of the top layer of model B are 20% and 43% lower than those of model A, respectively, and 17% of the relative displacement, 17% of the relative displacement of the vertices, and 17% of the absolute acceleration of the top layer. There are 22% and 7%. 3) the maximum interlaminar shear force of each layer of model B is smaller than that of model A. Therefore, partial column top slip reinforced concrete frame shear structure has better seismic performance than traditional frame shear structure.
