Effect of infill wall on the ductility and behavior of high strength reinforced concrete frames

Abstract EN

This paper presents an experimental study for the behavior and ductility of H.

S.

R.

C frames with infill wall under the effect of cyclic load.

The experimental program was conducted on four specimens (frames).

The parameters are studied change panel of frame from non infill to infill, change thickness of infill wall and change type of bricks.

The dimension of frames is selected to represent half scale frames and tested under cyclic loading.

All specimens of experimental program are tested in the reinforcement concrete testing laboratory at the Housing and Building National Research Center–Cairo.

From the representation and the analysis of the obtained results, the main conclusions are pointed out ; the lateral load resistance for infilled frames F2, F3 and F4 with infill wall (red bricks) thickness 12, 6 cm and cement bricks 12 cm, respectively was greater than the bare frame (F1) by about 184 %, 61 % and 99 %, respectively.

The ductility factor for infilled frames F2, F3 and F4 was less than the bare frame (F1) by about 57 %, 51 % and 46 %, respectively.
