| Our country is a mountainous, hilly country, many houses are built on all kindsof special site. This type foundations of houses is various, such as semidug andhalf-filled venues,just dug not filled venues and so on, one of the more commonarchitectural forms is that the houses which are built by mountains are multi-stepclimb transv-ersal Split, In order to reveal the seismic performance of this typestructure better only through the top and bottom interaction analysis. So the researchof seismic performance of structures which are built on various types of special site issignificance.The elasticity and plastic analysis of structure in this paper, background ofTianjin Jixian Jia hua Ou Ti Pa garden project, to the rock slope Base-BoxFoundation-Superstructure as the research object, using ABAQUS to buildthreedimensional solid model. The research includes two aspects: first, the analysis offoundation settlement under combined effect of rock slope Base-Box Foundation-Superstructure; secondly, seismic response analysis of structure under combinedeffect of rock slope Foundation-Box Foundation-Superstructure. The innovation ofthis article mainly includes the following sections:(1)After a reasonable simplification of No.56residential building in TianjinJixi-an Jia Hua Pa Ti Ou gargen project, we have established a reasonable dynamicfinite element model considering the soil-structure interaction and determined themethod for solving nonlinear dynamical equations.(2)The factors of structural subsidence affecting were analyzed. By changing thesuperstructure loads, load conditions, Poisson’s ratio of rock slope, modulus, cohesion,strata dip and other model parameters we conclude that, in the whole system, the upper building loads and strata dip changes impact are the key factors. Reducing thesuper-structure loads and selecting a rock foundation of smaller strata dip caneffectively reduce the uneven foundation settlement.(3)The supper-structure seismic performance of the rock slope Base-Box.Foundation has been analyzed. During the dynamical analysis the infinite elementboundaries were established, based on the original three-dimensional model. Bytyping indifferent directions, different types of seismic waves we carried on adynamical ana-lysis of the rock slope Base-Box Foundation–superstructure and drewsome regularity about the rock slope base-box Foundatio-superstructure seismicresponse which can be used by engineering designers. |
