Research on the Shear Strength of High-Strength Concrete Beams with Web Bars by Concentrated Load

Abstract

Based on the previous results on the experimental study of shear performance of high-strength concrete beam and the application of mathematical statistics theory, the page establish the shearing strength formula of high strength concrete beams under concentrated load . Comparing regression formula and GB50010-2010 calculated value with the experimental results respectively, it shows that the ultimate strength calculated by regression analysis matches with the experimental results well, but GB2010 calculated results is unsafe.
