Seismic Response of Adjacent Structure to Inter-Story Isolated Structure ()
ABSTRACT
Currently, land resources are becoming more and more constrained and
structures are getting closer to each other.
To
investigate the seismic response of inter-story
isolated structure to adjacent structure, models considering no
soil-structure interaction (SSI), considering soil-structure interaction (SSI),
and considering structure-soil-structure interaction (SSSI) were established.
Nonlinear seismic response comparative analysis was conducted by varying the
spacing between adjacent structure and inter-story isolated structure, as well
as the weight of adjacent structure, under different earthquake inputs, in
order to obtain the structural response characteristics. The results indicate
that the inter-story drift and inter-story shear of the inter-story isolated structure without
considering SSI are smaller than those considering SSI and SSSI. The inter-story drift and inter-story shear of the inter-story
isolated structure considering SSSI are further affected compared to that of the inter-story
isolated structure considering only SSI. As the spacing between adjacent structure and inter-story
isolated structure increases, the influence of adjacent structure on inter-story isolated structure decreases. The
variation in the spacing between the two structures has a negligible effect on
the isolation layer of the inter-story isolated structure. With the increase in the weight of adjacent structure, the influence of
adjacent structure on inter-story isolated structure becomes more significant.
The increasing weight of adjacent structure has an increasing effect on the
Isolation layer of the inter-story isolated structure.
