The Analysis Of The Seismic Response Of The High-rise Building With Slope Pile Foundation

With the pace of urbanization moving forward rapidly in our country, urbanpopulation is growing. The demand for housing has increased year by year bring aboutthat blocks of high-rise buildings were built. Our country in earthquake-prone zoneespecially many mountains in western region, frequent and unpredictable earthquakesand their strong destructive power have caused many accidents of slope, at the sametime also destroyed a large number of buildings and structures, so it is very necessary tostudy the slope structure response under the seismic action.In order to study high-rise frame structure response on slope under the seismicaction clearly，slope pile foundation of high-rise building space finite element model isestablished to analyze initial stress field，slope of ground stress achieve the balancepreliminary at this point，then based on that horizontal and vertical earthquake is studiedunder the action of earthquake，Slope topography influence on the response of the slopeand the upper structure；at the same time for the response of the high-rise framestructure under seismic action combine with the chain scission and mitigation ofdisaster chain theory method，the seismic slope high-rise frame structures under theaction of chain scission and mitigation methods were discussing.Through the analysis and research，conclusions are as follows：①Both under horizontal earthquake under the vertical seismic action，Homogeneous rock slope will amplified the surface peak acceleration at a certainextent，and slope will also affects them.②Under the horizontal and vertical seismic action，horizontal displacement offrame structure and shear force,bending moment and axial force of frame column arelarger than gravity effect. And with the increase of the high slope, displacement andinternal force of frame structure has a certain degree of growth.③For slope pile foundation of high-rise building under the action of earthquakedamage causes and damage form, put forward the slope of the high-rise building chainscission and mitigation methods.
