The Effect Of Soil And Structure Interaction On High-Rise Reinforced Concrete Buildings With Internal Resistant Core Tube In Tube System And With To Consider Nonlinear Dynamic Analysis

This research are considered and analyzed threedimensional  high rise building three frames of 28-story reinforcedconcrete in each direction X,Y structural structure of a tube in tube,In the zone of high relative risk(A=0.3g),With fixed number and  bays the length,different heights and types of soil(I, III), Once without affecting soil-structure interaction Once again, the effects of soil-structure interaction are considered and analyzed. The purpose of the present study is to determine the maximum lateral displacement frames floors of gravity loads(dead,live)and earthquake loads. In order to analyze the structure of the structurethe soil-structureintraction impact of the substructure is assumed to be used for the  modeling of the sub-surface soil from the cone model,the structure of the structure and the determination of the dynamic hardening coefficient and  damping coefficient  soil of the discrete model based on the cone model in the homogeneous space stream.In order to analyze earth quake loads  in the studied models,a  dynamic analysis of the nonlinear time history of the modal method under seven  accelerations accelerations.The geometric modeling of the all frames with shear walls in the SAP 2000-V17 software package was performed.The results show that with increasing elevation of floors(model 1 to 3),the maximum lateral displacment floors on type I soil in the direction of X increase in the direction Y is significant increase,in model ,in the model 2 to 1by changing the type of soil type, the maximum lateral displacment floors with out and with Soil-Structure intraction in the each two direction is dramatic increase.
