Abstract:
Applying theory of linear elast icity fracture mechanics to the analysis of high st rength concrete( HSC) compress-shear member. s cracking stress, a corresponding model is established in this paper. U nder the act ion of compression and shear loading , considering the mix ed mode stress intensity factors K Ñ , K Ò act ing on t ransverse and vert ical bar and based on G-criterion, a formula of calculat ing the HSC compress-shear member. s cracking st ress is developed and the curves betw een the cracking st ress and the af fecting primary factors are given at different ang le cracks.
