新型装配整体式板-钢框架结构模型振动台试验研究

为了研究新型装配整体式板-钢板剪力墙钢框架结构的抗震性能,对一个非对称体型新型装配整体式板-钢板剪力墙钢框架结构进行了1/4整体模型模拟地震振动台试验,试验得到结构在地震动作用下的加速度响应、位移响应以及应变响应;该结构能够满足抗震规范的要求,加载到罕遇地震时,混凝土板出现了局部微裂缝.不浇现浇面层的装配式整体式预制楼板与工字钢梁连接良好,新型装配整体式空心板表现出较好的抗震性能.本文分析了强烈度地震作用下结构的地震反应、破坏形态,给出了结构薄弱部位的构造设计意见,为同类结构的抗震设计提供了试验依据.

Shaking table test study on a new assembled monolithic floor-steel plate and frame shear wall structure

In order to study the new assembled monolithic floor-steel plate and frame shear wall structure seismic behavior,we conducted the whole model a quarter a shaking table test to a new type of asymmetric size assembled monolithic floor-steel plate and frame shear wall structure. Through the new structural test, we obtain the acceleration, displacement, strain response of the structure under the earthquake. The structure displays the obviously torsion effect. The floor appeared local cracking phenomena under the effect of strong earthquake and cast-in-situ surface assembled concrete floor slab without poured has a good connection with i-steel beams. The new assembly and hollow slab have a good seismic behavior. This paper analysis the seismic response and failure mode of structure under the strong earthquake gives the constitution design suggestion to the weakness of structures and provides the test basis for the similar structure of seismic design.
