| Abstract: | By means of the comparative experimental research on six cast-in-place mini-prestressing concrete plates with cold-rolled ribbed bar,this paper expounds variations and relations with reinforcement ratio and temperature,humidity of strain and stress of reinforcement and concrete in the component's curing period.By way of the short-term destructive tests,the authors describe experimental property of components in the all test-stages.That provides experimental basis to the application of mini-prestressing concrete structure with cold-rolled ribbed bar. 5figs., 3tabs., 6refs. |
