Analytical Practices to Obtain Efficient Concrete Grade in Outrigger Walls below Plinth Level in Multistorey Building

Abstract

To make the structure that would be free from lateral effects, some of the additional components should be implemented to it to make it safe. Some of the supplementary components are shear wall, bracing elements, belt supported system, outrigger wall system etc. These supplementary components when added to the multistoried fascinating and high rise structure can make it stiffer that ultimately fulfill the living needs. These add-ons make the structure safer for various horizontal and vertical irregularities. In this study outrigger system is taken for analysis by implementing the outrigger walls below the plinth level. Previous studies shows the outrigger system used at a particular height, but none of the researches shows this kind of the structural stability research approach. The main objective of the current theme is to prove the optimum grade of concrete that can be used when this kind of approach is adopted. Total 8 cases were selected, analyzed and compared among each other to select the optimum one. Building case OT8 observed and obtained as efficient case and should be recommended when this type of stability in building will be provided.
