Study on Cracking Resistance of Concrete Reinforced with Rib Stiffened Steel Plates

摘要

Aimed at the question of excessive tension stress in local area in concrete structure, a ribbed steel plate-concrete composite structure(RSPC) which can improve crack resistance and prevent crack developing was proposed. Four specimens of RSPC flexural members were designed to be compared with common concrete flexural members. The test results show that RSPC, which cracks appeared in upper limb, have much more crack resistance ability than common concrete flexural members. According to energy absorption principle in failure process of composite materials, the crack mechanism of RSPC composite structure was studied.
