摘要

An experimental research is carried out on some composite structural elements made of concrete composites including cracks and advanced composite materials of carbon fiber reinforced plastics sheets (CFRP) composed to these concrete beams for strengthening and repairing purposes for the cracked zones. The beams are pre-cracked mainly to study the effect of the repairing and strengthening for the cracked elements by means of the new production of the advanced fibrous composites. Also, the study included carbon fibers bonded to some non-cracked concrete beams for studying it as a new structural composite system. This research is made experimentally to investigate and check the effect of CFRP as a new advanced composite material on the capacity of the structures to resist the additional stresses resulting due to cracks. A mechanical model is introduced. The study is made under static loading but it can be extended easily to cyclic and dynamic loading conditions.
