EFFECT OF OPENINGS ON THE BEHAVIOUR OF FIBRE REINFORCED CONCRETE AND MASONRY INFILLED RC FRAMES

摘要

This paper presents an experimental investigation to study the effect of openings on the strength and behaviour of reinforced concrete (RC) frames infilled with precast fibre reinforced concrete panels. One bay-three storey, 1/4th scaled down model frame specimens were constructed and tested under reversed cyclic lateral loading. The parameter investigated was the shape of the opening. The precast panelled frames were also compared with the traditional brick masonry infilled frames. The test results indicated that the strength, stiffness and energy dissipation capacity of fibre reinforced concrete infilled frames considerably improved when compared with bare frame and brick masonry infilled frames.The test results also indicated that fibre reinforced concrete infills with openings significantly improved the performance of RC frames when compared with the brick masonry infills.
