Evaluation of RC Elements Under High-Temperature Conditions with different Locations: Analytical Investigation

Abstract

Abstract Developments in the field of construction has taken an encompassing transformation in the design of structures. Concrete technology has also seen several advancements with the inclusion of reinforcement materials like steel and iron in them which are called as the (RC) Reinforced Concrete. Amidst several developments in the technology of the structural design for a quality construction, RC structural element failure under higher temperature with load remains as one of the most critical mechanisms to be addressed with the recent advancements. There are several methods and studies that try to rule out such failure mechanism with certain improvised methodologies in the fire resistivity behavior of concrete structures. Nevertheless, only a few studies have concentrated on the interaction between the structural and functional elements in the emergence of fire. Considering this, the present work concentrates on the behavior of RC infilled frames with elements like beam, column and beam column joints under higher temperatures and load for which the ABAQUS finite element software is used. The model is simulated with a transient state analysis and characteristics like deflection, stiffness, principal stress are studied for the RC beam, column and beam column joints with varied temperature and load. The outcome of the simulation shows the effect of load and temperature on RC elements and the respective performance graphs are plotted.
