ANALYSIS AND IMPLEMENTATION OF SHEAR WALL ON HIGH RISE BUILDINGS WITH DIAGRID SYSTEM (KEY IJP************773)

Abstract

A building, or edifice, is a structure with a roof and walls standing more or less permanently in one place, such as a house or factory. In the late 19th century early designs of tall buildings recognized the effectiveness of diagonal bracing members in resisting lateral forces. Most of the structural systems deployed for early tall buildings were steel frames with diagonal bracings of various configurations such as X, K, and eccentric. However, while the structural importance of diagonals was well recognized, their aesthetic potential was not explicitly appreciated. Thus, diagonals were generally embedded within the building cores which were usually located in the interior of the building. In this paper, analysis and design of 18 storey diagrid RCC building is presented in detail. A regular floor plan of 24 m 30 m size is considered. STADDX pro. software is used for modelling and analysis of structure. All structural members are designed using IS 800:2007 considering all load combinations. Load distribution in diagrid system is also studied for 18 storey building. Also, the analysis and design results of all diagrid structures are presented. From the study it is observed that most of the lateral load is resisted by diagrid columns on the periphery, while gravity load is resisted by both the internal columns and peripheral diagonal columns. Analysis results like storey displacement, inter storey drift are presented here.Keyword: - Rectangular Building, H- Shape of Building, I-section steel girders, Diagrid
