【摘要】：型钢混凝土框支剪力墙结构具有延性好、受力特性明确等特点,在转换结构中应用广泛。但目前针对此类结构的地震易损性方面的相关研究较少,也缺乏相应震害资料,整体结构抗震性能研究仍不充分。因此,为研究型钢混凝土框支剪力墙结构在不同地震水准作用下的抗震性能,以某实际工程为背景,建立了非线性分析模型,采用基于增量动力分析的方法对结构进行地震易损性分析,建立起地震动强度与结构破坏程度之间的关系,对结构的抗震性能做出评估,预测结构达到各种极限状态破坏时的失效概率。分析结果表明:结构在小震作用下能够保持完好,基本未出现损伤;中震作用下结构产生轻度损伤,损伤仍处于可控范围;罕遇地震作用下结构产生倒塌破坏的概率很低,抗倒塌能力储备充足。
[Abstract]:SRC frame-supported shear wall structure is widely used in the conversion structure because of its good ductility and clear mechanical properties.However, there are few researches on the seismic vulnerability of such structures, and the corresponding seismic damage data are also lacking, so the seismic performance of the whole structure is still insufficient.Therefore, in order to study the seismic behavior of steel reinforced concrete frame-supported shear wall structures under different earthquake levels, a nonlinear analysis model is established based on a practical project.Based on the incremental dynamic analysis method, the seismic vulnerability of the structure is analyzed, and the relationship between the intensity of ground motion and the damage degree of the structure is established, and the seismic performance of the structure is evaluated.The failure probability is predicted when the structure reaches various limit state failure.The results show that the structure can be kept intact under the action of small earthquakes, and basically no damage occurs; under the action of moderate earthquake, the structure is slightly damaged, and the damage is still in the controllable range, and the probability of collapse and damage of the structure under rare earthquake is very low.Adequate reserves of collapse resistance.
