Behavior of Low, Medium and High Rise Reinforced Concrete Frame with Infill Using ATENA 2D

Abstract

The Low, Medium and High rise reinforced concrete (RC) buildings are common in all cities in all countries. Unreinforced masonry wall (URW) is commonly used in low, medium and high rise building as a partition wall both in interior and exterior of building. But structural designers are not considered URW in analysis and design of buildings. This URM wall as an infill plays a very important role in structure subjected to lateral load. So it is very essential to know the nonlinear behavior of low, medium and high rise frame with and without infill. To conduct experiment for understanding the nonlinear behaviour of low, medium and high rise RC frame is very expensive and need good sophisticated testing facilities. With the available many finite element softwares, it is easy to create model and to know the performance of structure. So in this study, a finite element software ATENA 2D (2003) were used to conduct nonlinear analysis for capture nonlinear behaviour of low, medium and high rise RC frame with infill and without infill. Load versus displacement graphs, magnitude of principal compressive stresses, magnitude principal tensile stresses, stress contours, and cracks pattern are used to know the performance of low, medium and high rise RC frame with infill.
