Performance of Diagrid Structures

Abstract

Diagonalized grid structures, also known as “diagrids system,” have appeared to be innovative and adaptable advancement in the structural design of buildings in this millennium. These diagrids provide lateral stability to the building. While designing a high-rise building, importance should be given to lateral loads that act on the structure, such as wind loads and earthquake loads. In recent years, diagrids have proven as an efficient lateral load resisting system. In diagrid structural systems, inclined columns are provided on the periphery of the conventional buildings in place of vertical columns. Researchers have studied the effect of diagrids in various angles of inclinations and the complexity of the structural system when the building is twisted. In this particular study, importance is given to understand the behavior of the building when the diagrid structural system is provided from the base and ground level. Modeling and analysis of the structure are done with the help of ETABS software. Results are evaluated in terms of base shear, maximum story deflection, story drift.
