The building sets up reservoir slope, in order to avoid mass of excavation and fill geotechnical Engineering,according to the change of slope angle, pile foundation is generally made into different height. the foundation of building is Considered apart from Superstructure in general design. in the normal loading condition to satisfy coordination between bearing capacity and strain. But accidental loading is acted to the type of construct whether satisfy up,the strain of lower part structure moderate and is then canned not know by force condition. According to this, with some library coast of the 5 F frame stake foundation for instance, adopted FEM software ANSYS to analyze to carry to act in the earthquake force, pile foundation -soil- Superstructure common coupling action and general design, while carry on internal force and strain result under two kinds of conditions of contrast analysis. While analyzing a result to express the type of building structure to design should well in consideration of the stake and soil, lower part structure thus makes design for effecting upside structure more safety reasonable.
