PERFORMANCE OF LATERAL SYSTEMS IN TALL BUILDINGS FOR VARYING SOIL TYPES

Efficient lateral systems, decreases the lateral deformations caused by the seismic forces in the buildings. In this work, it is proposed to carry out an analytical study, on multistory buildings of 10, 20 and 30 stories, was carried out accounting f or different seismic zones and soil types. The suitability and efficiency of different lateral bracing systems that are commonly used and also that of concrete in fills are investigated. The different b racing systems viz., X-brace, V-brace, inverted V or Chevron brace, Outriggers and in fills, are introduced in the buildings through analytical models.
