Enhancement of Interaction Between Infilled Wall and Rc Framed Structure

Abstract

Normally, Reinforced Concrete (RC) framed structures are formed through structural and non structural elements and structural elements are designed in RC framed structure. Non structural element likes infilled wall is not designed but it is used to fill the openings and separation of room in buildings. However, some percentage of behaviour between infill and frame can take itself at the time of loading. According to that, the aim of the project is to improve interaction between RC frame and infilled wall. In this project, three types of specimen were prepared for studying the influence of infilled wall in framed structure by through single bay, single storey specimen with one-tenth scale model as RC framed structure without infilled wall, RC framed structure with infilled wall, RC framed structure with infilled wall under strengthened by connector. Here, properties of concrete and steel were also measured for analysis of experimental work. Besides, the specimens were prepared under earthquake detailing and testing of specimens was carried out through the Universal Testing Machine. Experimental values are compared in the order of strength, ductility and failure mechanism of the specimens. Finally, the ultimate load carrying capacity of RC frame with connector is 1.633 times greater than that of RC frame without infilled wall. The initial stiffness of the RC frame with connector was 1.131 times higher than that of the frame without infill. The ductility of frame with infilled wall is 4.44 times greater than that of frame with infilled wall.
