Experimental Evaluation of the Cyclic Behaviour of Scaled (1:3) Reinforced Concrete Frames

This paper presents laboratory test results for two-column one-bay reinforced concrete (R/C) bare frames with or without masonry infills for 1:3 scale prototypes when the top beam is subjected to horizontal cyclic loading using 50kN axial load per column. It is well documented that infills affect the dynamic characteristics of building structures. At the same time, their uncertain behaviors have also been recorded. Many parameters, such as the infill materials, reinforcing of infills, connection to the surrounding frame by means of surrounded joint contact, local techniques, and others affect structural system behavior. The masonry infills increase the overall horizontal lateral strength and stiffness and partially structural strength; hence, proper use can positively affect the general seismic behavior.
