Frame Shear Wall Structure Under Seismic Action Of The Dynamic Characteristics

Frame-shear wall structure is one of the main types of building structure design, at the same time, it is also a kind of structure form which is widely used in modern city architecture, it includes the advantages of the framework and the shear wall of their separate actions, and can both work together effect fully reflected, to help each other to restrict each other to resist horizontal earthquake load, the lateral form of the structure graph is bending shear type curveA residential project of Chengguan District of Gansu city in Lanzhou Province, located in the Chengguan District on the west side of West Cross buildings in Asia and Europe construction area of 35200 square meters,in total for the 14th floor above the ground, the first story is 4.5m, the rest of the various layers of high is 3.3 m, total height of structure 47.4m, structure type is a frame shear wall structure.After detailed classification by means of the original structure. the use of spa2000 structure design finite element software to explore the analysis of the relatively clear and clear a lot of.In this paper, we first study the vibration mode of the two models, the model and the model are unified in the two structural forms, after the mode is loaded, the first 12 order modes and the mass participation coefficients of the model are compared,and then add the seismic response spectrum to these four kinds of structural modes, inductive statistics out under different conditions of shear displacement, the interlayer displacement Angle, floor structures such as the summary, finally, a model is represented as a model.The above research proved, frame-shear wall structure to collapse, its earthquake resistant wall is the first occurrence of damage, therefore, the bottom of the frame should be set for rigid connection and can not be a key point for the design of the design considerations.This paper make full use of the spa2000 finite element software, Autocad drawing tools, PKPM structure design software of related functions, analysis of two kinds of models under two models, refer to the sample data in the practical engineering, such as the site category, seismic fortification intensity, earthquake group, characteristics of the cycle.
