BEHAVIOR OF SPECIAL REINFORCED CONCRETE FRAME AND NORMAL FRAME WITH OR WITHOUT MASONARY INFILL by Jaspreet Kaur
Abstract
Comprehensive study has been led to access the security of existing masonry infilled frame under earthquake loading. The reinforced concrete frame is generally constructed with unreinforced infill or
reinforced infill. Although masonry infill walls are used in buildings very commonly but its influence is not considered in any code. IS 1893 considers the impact of infill just as far as normal time of vibration. But same equation is also used without infill. Thus effect of infill is not considered due to lack of sufficient information. In this research work investigation of masonry infilled frame and bare frames using FEM based ATENA 3D software. To study the means and methods of modeling of RC infilled frames and bare frames, a review of work is conducted. Micro modeling approach is used for modeling of infilled frames. In this study finite element analysis is done to conduct the behavior of RC frames . It showed that RC frame with ductile detailing gives more load carrying capacity than non-ductile frames. This approach of modeling is quite difficult and time consuming but this approach is best suitable to check the effect of masonry infill.
