摘要: 在双面叠合剪力墙结构中集成夹心保温材料,设计形成适用于低层建筑的双面叠合夹心保温剪力墙结构,该结构具有构件生产和施工优势,具有应用推广前景。 为研究该体系的抗震性能,对一栋两层两开间足尺模型进行地震振动台试验,分析结构在不同工况下的损伤累积过程,研究试验模型动力特性和地震响应的变化规律。 试验表明,该结构在 7 度多遇、7 度设防地震作用下基本保持完好,在 7 度罕遇、8 度罕遇、9 度罕遇地震作用下,试验模型自振频率出现一定下降,外观出现裂缝并随着地震作用的增强而不断发展,但结构没有明显的破坏现象,基本性能稳定。 试验模型能够满足现行抗震规范三水准的设防要求,在低层建筑中具有一定的应用优势。

Abstract: Integrate the insulation material into the double-faced superimposed sandwich shear wall, a double-facedsuperimposed sandwich insulation shear wall structure suitable for low-rise buildings was designed. This structure has theadvantages of component production and construction, and has application and promotion prospects. In order to study theseismic performance of the system, a full-scale two-story two-bay structure model was subjected to seismic shaking table testto analyze the damage accumulation process of the structure under different seismic conditions, and to study the dynamiccharacteristics of the text model and the change law of seismic response. Tests have shown that the structure remainsbasically intact under the action of 7-degree frequent and 7-degree fortified earthquakes. Under the action of 7-degree, 8-degree, and 9-degree rare earthquakes, the natural frequency of the text model drops to a certain extent, and theappearance cracks appear and continue to develop with the increase of seismic action, but the structure has no obviousdamage, and the basic performance is stable. The text model can meet the three-level fortification requirements of thecurrent seismic code, and has certain application advantages in low-rise buildings.
