Behavior of Linked-Column System subjected to Seismic Force

Objective: The study investigates the seismic performance of reinforced concrete linked column frame system under earthquake acceleration. The utilization of concrete as link elements to resist shear and optimize its connection to the columns for shear transfer has been presented. Methods/Analysis: The seismic responses of the systems was investigated for ground motions using time history analysis for Linked Column Frame for three building models namely, 4, 7 and 10 storey building and the results were compared with the normal frame using SAP 2000. Findings: Adding linked column to the normal frame shows that the inter storey drift and base shear are effectively reduced. Results of nonlinear time history analysis show that this system has better load dissipation capabilities. Conclusion/Application: Since the replaceable links are also modelled as reinforced concrete elements the cost of construction can be greatly reduced.
