Abstract
Since the behavior of a conventional reinforced concrete (RC) bending member
is closely related with the emergence and propagation of cracks in concrete, the
RC member can be improved in service and carrying ability through holding
back the growth of cracks. Based on the fundamental theory of fracture
mechanics, a new design concept to improve the performance of the RC member
by means of embedding a crack-arresting FRP layer into concrete is proposed in
the paper. The cracks are effectively restricted this way and the performance of
the RC member can be better. Guided by the above analysis, some RC bending
members with embedded crack-arresting FRP layers were fabricated and loaded
in the lab. The experiments verified the new design concept based on fracture
