SEISMIC REACTION OF BUILDING FRAME UNDER VARIOUS ZONES CONSIDERING FLEXIBLE AND RIGID SUPPORTS

Objectives: To find seismic reaction of building frame under various zones considering flexible and rigid supports. Methods/Analysis: If a structure is subjected to an earthquake excitation, it interacts with the foundation and soil, and the ground motion is varied. That means, the movement of the whole ground structure system is under the influence of soil type also by the type of structure. As the seismic waves transfer from the ground which consist of alteration in soil properties and performs according to soil's respective properties differently. In this study, different soil strata are taken and corresponding vertical and lateral displacement are determined with G+4 in zones II, III, IV and V. A G+4 building is modeled in STAAD. Pro for different types of soils such as hard, medium and soft. Findings: The work consist the calculations of vertical and lateral support reactions for soil types in various seismic zones and the comparison of Rigid and Flexible supports is obtained. Applications: Effect of seismic reaction of building frame under various zones considering flexible and rigid supports concept can be extended to different types of buildings and number of bays and storeyes can be increasd further the analysis can be carried out for the different types of zones using STAAD - PRO.
