Energizer Reinforced Lightweight Aggregate Concrete Beams Carrying The Pilot Study

The article researches bearing state and failure mechanism ofSRLC structure through l2 steel-reinforced lightweightaggregate concrete beam oblique section capacity test Combiningcurrent 《Specification for Design of Steel-Reinforced concreteStructure》 (YB 9082-97)with 《Specification for Design ofLightweight Aggregate concrete Structure 》 (JGJ 12-99),theorically analyzes SRLC structure oblique section capacity. Itsinfluence factor includes: shear span, hoped reinforcement ratio,lightweight aggregate concrete strength, steel reinforcement stress,etc. this article also verificate above influence factor by test data.Result shows anti-shear capacity with relation to shear span; whenshear span varies from 1 to 3, with shear span increasement,oblique section anti shear capacity decreases; when shear span islarger than 3, anti shear capacity varies steadily, with hopedreinforcement ratio incensement oblique section capacity increases;with light weight aggregate concrete strength increasement, itscapacity also increases. Through stress analysis, we can find thatflange plays an main role in shear capacity. finally, article writersummarizes anti shear capacity formula, accessed to test result.
