Earthquake-resistance Performance Analyzes And Researches On Tall Building With Transfer Thick Plate

The mass of this paper is to analysis earthquake-resistance performance of tall building structure with thick plate transition. To generalize earthquake-resistance rule and chief influencing factor.First, this paper introduces research state of tall building structure with thick plate transition .At the present time, the researching of tall building structure with thick plate transition is not deep. Specially, the researching of earthquake-resistance performance to this structure is not systematic. Pass force path is not clear. Because of the mass of thick plate transition floor focusing, earthquake-resistance performance is very complex. To the deficiency of researching, by two software SATWE and ANSYS, the paper analysis earthquake-resistance performance of tall building structure with thick plate transition,By calculation of calculated example, adjusting ratio of rigidity of structure up and down transition floor, Generalizing the influencing of ratio of rigidity to tall building structure with thick plate transition, and extracting simultaneous controlling two kinds of ratio of rigidity and two kinds of ratio of displacement. The two kinds of ratio of rigidity are the ratio of the rigidity of the structure up and down transition floor and the ratio of the rigidity of the two adjacent floors up and down transition floor. The two kinds of ratio of displacement are the radio of floor angle of the two adjacent floors up and down transition floor and the radio of the floor displacement of two adjacent floors up and down transition floor;When the position of thick plate transition floor is different, the paper studies the influence to earthquake-resistance performance and earthquake response;to study the influence of occasional eccentricity to this structure;to study the influence of the rigidity of beam to this structure;to study the influence of the rigidity of the plate thickness to this structure;by ANSYS, creating three-dimensional finite element mode of tall building structure with thick plate transition, to calculate by two methods of modal decomposition and temporal analysis, getting the figure of stress distribution of the thick plate transition;by the method of temporal analysis, the distribution of floor shear is not reducing always from down to up, and the floor shear enlarge in the intermediate floors.By analysis, if the redistribution of the structure is proper, and the calculated parameters are selected properly, at 7 degree protected earthquake intensity, tall building structure with thick plate transition can be access.This paper generalizes the regularity of earthquake-resistance performance of the tall building structure with thick plate transition, and extracts some suggestions. That can give designer some references by this paper, and can popularly use tall building structure with thick plate transition in the area of civil building.
