Seismic Assessment of Reinforced Concrete Structures Coupled with O-Grid Bracing Systems

Kundan T. Rathod, Sandhya K. Swami

Abstract


The greatest challenge for structural engineers is to design the structures to be earthquake resistant. Basically, the earthquake-resistant design of reinforced concrete structures is a force-based design. When a structure is designed for seismic resistance, various systems are embedded into the structure so as to resist the lateral forces. One of the systems, which are used for resisting lateral forces, is to provide the structures with different types of bracings. There has been a wide use of bracing systems for such purposes. In this paper, focus has been given on O-grid bracings. The resulted parameters such as base shear, maximum storey displacement and time period and frequency of O-grid bracings system is compared with bare frame and their effect has been studied.

Keywords
