In recent years, archaizing architecture are more and more favored by architects. As a kind of archaizing architecture, XieShan type reinforced concrete archaizing architecture is widely used because of its features of beautiful lively modeling and strong attitude performance. However, the lack of relevant standards specifically for archaizing architecture result that the design of archaizing architecture exsits many uncertainties.This article is based on the engineering background of a XieShan type reinforced concrete archaizing architecture, by finite element simulation method and according to the characteristics of this kind of structure, the spatial finite element model of XieShan type reinforced concrete archaizing architecture is established and then its static characteristics and dynamic characteristics is analyzed. The main conclusions are as follows:(1)The phenomenon that XieShan type reinforced concrete archaizing architecture presents “top-heaviness” in weight distribution is found,but this phenomenon is harmful to the elementary force of structure and the seismic resistance of structure,to which enough attention should be paid.(2) Under the action of static load, Vertical displacement and lateral displacement(Y direction)of the roof girders in overhanging eaves portion are very lager;The column at the end of the main ridge of the small and large Xieshan roof is pulled serious; these locations are the weak links of the structure and strengthening measures should be taken in structural design. in addition, it is found that the frame column with periphery on the roof part are short column, it should be as far as possible to avoid such short column in structure design.(3)The related dynamic parameters of stucture meet the requirements of relevant standards and the overall dynamic characteristics of the structure is good,but the higher order mode of the structure is mainly based on local vibration,this phenomenon is harmful to the structure force.(4) Under the action of seismic load of response spectrum, using the displacement at X direction(Y direction) of each frame column to measure the displacement at X direction(Y direction) of the whole structure is feasible. The horizontal deformation of the roof section is very small, therefore, the roof section can not be controlled when checking the story drift of the whole structure. Some of the frame column with periphery on the roof part are short column, it should be as far as possible to avoid such short column in srivture design.(5)Under the time-history excitation at X direction, the average of the peak at X direction in each level of different frame columns is very close,that shows the constraint at X direction that horizontal floor and slope roof providing to frame column is strong. Under the excitation at Y direction, the average of the peak at X direction in 6.00 m ? 12.00 m level of different frame columns is very close,but at the top of frame columns is slightly different,which shows the constraint at Y direction that horizontal floor providing to frame column is strong, the constraint at Y direction that slope roof providing to frame column is weaker. Overall, with the increase of elevation, the peak of displacement and acceleration at X direction(Y direction) of overall structure shows increasing trend, but the peak of displacement and acceleration at X direction(Y direction)at maximum elevation(that is, the main ridge of XieShan roof) are not necessarily the maximum of displacement and acceleration at X direction(Y direction) of overall structure.
