Behavior of short span composite beams strengthened with CFRP strips

الملخص EN

The experimental program in this paper is divided into two groups : the first one consists of seven composite beams ; six of them were strengthened with one and two CFRP strips and with three different percentages of full beam length (40%, 60%, and 100% ) .

The second group consists of five composite beams strengthened at the face of the bottom flange with CFRP strips fastened to the steel section by steel bolts with two different length proportion of CFRP strips to beam soffit (60%, and 100%(.

The analytical investigation included the use of three dimensional nonlinear finite elements to model the performance of the composite beams using (ANSYS 8.0) computer program.
