Study On The Seismic Performance Of Peripheral Structure With High Converting Layer

In recent years, the high-rise buildings have spread across both China and foreign countries. In the meantime, to meet the demand of appearance and functions, so-called "urban comprehensive" comes up, with more complex structure and multi-functions. Generally.it is necessary to lay out transfer structure at structural transition floor when big vertical difference exists between upper part and lower one or column grid axis varies from upper to lower.Lapping column transfer is a new transfer structure system, which is being more popular recently.In general, when the peripheral structures concave or protrude in vertical direction, it is suggested to use Lapping column transfer structure.This kind of structure is outstanding in construction practice and very economical in terms of cutting down budgets. However, relative research and methods are nor sufficient in constructional applying.This article has introduced the concept of Peripheral structure and high-location transfer structure, and carry out the discussion induction of applying lapping column transfer into high-location transfer peripheral structure.In modeling of Botai0728Project, this article carry on the response spectrum analysis by PMSAP, carry on the elastic time-history analysis under the frequent earth quake situation by SATWE. The study of seismic actions under severe earthquake are also calculated by elasto-plastic time history analysis using EPDA. A full assessment of seismic performance in the peripheral structure with high converting layer is proceeding.This paper also use the finite element software such as Abaqus to analyze the lapping column joints, and SAP2000to analyze the connected beams and slab.so as to study the distribution of internal force of lapping column structure.then summarize the practical method in terms of lapping column structure design.
