In the first phase of the research, five steel-CFRP bonded double-lap shear coupons were tested at different temperatures to characterize the bond behavior. In the second phase of testing steel beams were strengthened with different configurations of high modulus CFRP plates and subjected to different combinations of applied load and ambient temperature. The temperature ranges considered were selected to represent typical environmental conditions experienced by many steel bridges and structures in different environments. The parameters that are considered in this study include the length of the CFRP plate and the combined effect of mechanical and thermal load.application/pdfengThe author of this work is the copyright owner.
