PARAMETRIC STUDY OF DIAGRID, PENTAGRID AND HEXAGRID STRUCTURAL SYSTEM

Abstract

Tall building or High rise structures construction are more in this era; due to increase in population, economic prosperity and also due to the scarcity of lands high-rise structures are preferred. Height is main criteria in this kind of buildings, demand for tall buildings has increased because of increase in demand for business and residential space, advances in constructions, high strength structural elements, materials and also various software like Etabs, Staad pro etc these are analysis and design software’s have provided growth of high rise structures. Due to the heavy urbanization and population growth, the cost of land is increasing rapidly and the land
availability has become a constraint for developers & builders. And this creates a picture of vertical growth as natural process. Control of lateral responses keeping an eye on constructability & cost become order of the day for structural engineers. The increased wind pressure due to the large exposed area of the building, high intensity of the wind at higher elevations and the earthquake loads add to the bulk of structural forces. Recent design trends in tall buildings pose new challenges to structural designers, in addition to the traditional requirements for strength, stiffness, ductility and system efficiency.
