Analysis On Seismic Behavior Of Sloping Field Building Structure

China is a mountainous country, there are many towns in the mountains or the gully region, as the economy develops, more and more buildings have been built in the slopes, and this has brought a lot of construction problems. In the rocky mountains, a common solution is to set the building area in the excavation, the building is a certain distance back rock slope, the structural design design according to the normal situation. However, the common slope is the earth slope, when the construction site is not the height difference, the projects will generally be at the side of a layer of external walls and retaining wall design. However, there is not appropriate analysis and calculation procedures about this approach, the structural design actually choose different partial fixing designed to ensure the safety of the structure. However, some engineering design does not consider the role of retaining wall, Intuitive sense of this approach is clearly wrong, and may cause construction torsion. This article by practical example using the finite element software SAP2000 finite element model, and use only a single direction spring stiffness of the surface to simulate the role of outdoor soil slope, while this paper analyzes the outdoor soil on the impact of the upper structural deformation and internal force. Main conclusion includes the following:(1) This paper details the characteristics of slope construction, and selected groups of typical slope structural engineering practice, such as frame structure, frame structure and wall structure, and introduces the slope seismic design method for building structures.(2)This paper applies the common structural design software PKPM, and selects different partial fixing of the three groups structures on the slope to finite structural finite element model, and makes on the structure of modal analysis and response spectrum analysis, and compared the different results of the analysis in different partial fixing position.(3) Use of spatial finite element software SAP2000, this pape selects a different partial fixing of the three groups the structure to finite element model, and makes modal analysis and response spectrum analysis, comparing the results of their different partial fixing positions; The calculation results of the same structure and same partial fixing were compared with the calculation results of the SATWE.(4) Without considering the role of soil slopes, under different partial fixing positions of the three groups structure this paper using the SAP2000 finite element software makes elastic time history analysis; considering the role of soil slope, under different partial fixing positions of the three groups structure this paper using the SAP2000 finite element software makes elastic time history analysis; and compares calculation results of without and with considering the effect of soil slopes, and the response spectrum analysis results were compared with elastic time history analysis results to evaluate slope structural envelope design reliability, and put forward the proposal applied to practical projects.
