超高层装配式正交斜放空间钢网格盒式筒中筒混合结构在不同场地特征周期下的地震响应

The Semitic Response of the Assembly Integral Spatial Steel Grid“Tube-In-Tube”Cassette Super High-rise Structures in Different Characteristic Period

采用振型分解反应谱法分析了在不同场地特征周期下传统装配型钢密柱与混凝土核心筒组成的筒中筒混合结构和新型装配式正交斜放空间钢网格盒式筒中筒混合结构的地震响应,包括层剪力,层间位移和层间位移角。分析表明,新型盒式筒中筒结构与传统混合筒中筒结构在不同场地特征周期下地震响应具有相似的变化规律,因此可以借鉴传统混筒中筒混合结构的地震响应规律来评价新型盒式筒中筒混合结构的抗震性能。

By response spectrum analysis in different site characteristic period seismic the seismic response of two super high-rise buildings,the traditional hybrid tube in tube composed with the assembly steel column and concrete core tube and the box hybrid tube in tube composed with the orthogonal diagonal collaborative type steel open web plate floor and the grid steel frame wall structure,was obtained,including the base shear force,story drift,the story drift angle. The results show that the seismic response of two different super high-rise structure is similar,and the property of seismic response,design method and the seismic performance of the traditional hybrid tube in tube structure is applied to the box hybrid tube in tube structure.
