| Abstract: | An overall review is undertaken on the current progress of cracking shear force calculating for RC beams.The anti-cracking main influencing factors are discussed.The calculation formula is proposed based on the results of 69 test data of deep flexural beams using a regression analysis with 95% degree of confidence,which can estimate the anti-cracking capacity of deep flexural beams.The results by this formula coincides with the test data. |
