Abstract

Determination the story lateral displacement and vertical settlement in raft foundation of multi-story building are critical especially with presence of effect the soil bed where they are working together as phenomena of soil structure interaction .in this paper a three type of soil in addition to wide range of raft foundation thickness (from 0.3 to 1.3 m) are used to represent the foundation system in addition to reinforcement concrete buildings consisting of 4 stories up to 12 stories with spacing columns of (5m, 6m and 7m) subjected to different types of loading related to the gravity load and lateral loads (seismic and wind load ) as results from this variations in cases and parameters a more than 300 models are used in this study which induce a thousands of results by using finite package to obtain a database which are used to fulfillment the goal of this study, a good results was obtained , where coefficient of , r and r2 are equal to 0.9 and 0.81 respectively in case of vertical settlement in the raft foundation due to different type of loading .0.98 and 0.95 represent the r and r2 respectively for the story lateral displacement due to wind load finally the r and r2 are equal to 0.84 and 0.71 respectively in case story lateral displacement due to the seismic action.
