无黏结预应力型钢混凝土梁受弯承载力试验研究
Experimental study on flexural bearing capacity of unbonded prestressed steel reinforced concrete beams
摘要
Abstract
This paper studied the flexural performance of five unbonded prestressed steel reinforced concrete beams (USRCB), one unbonded prestressed concrete beam (UPCB) and one steel reinforced concrete beam (SRCB) by experiment. Crack modes, flexural performance and variety law of stress increment of unbonded prestressed tendons were analyzed in detail. Based on the theory of reinforcement concrete structure, flexural capacity formula of USRCB was proposed and calculation results was in good agreement with the test results. The article has certain innovation and practical value.关键词
