For reinforcement concrete corbel with the shear span to depth ratio ( a / ho ) less than 1 , has its performance of mechanics that is close to cantilever deep beams , it is an important kind of components in architectural structure which sustains roof trusses , brackets , tray " beams , frame " beams , wall " beams and crane " beams

Abstract : based on the systematic analysis of the shear behavior for r . c . beams , the tests of 11 simple supported beams under the top concentrated loads and the uniform loads are supplemented . the prime variable is shear span ratio , span depth ratio , horizontal web reinforcement ratio and vertical web reinforcement ratio . according to the test results , the working behavior , the prime shear failure modes , the effect of concrete and web reinforcement ( horizontal web reinforcement and vertical web reinforcement ) and other aspects of r . c . beams are analysed . the uniform calculation method for shear capacity of deep beams , short beams and shallow beams for practical is presented

A deep beam model with spring bearing is given , based on the analysis of middle frame of frame and shear wall structure ground floor , which is sensitivity to floor rigidity . comparing rigid assumption to elastic assumption , shear error of frame is worked out , which is index of floor rigidity . conclusions are drawn that floor rigidity is independent of earthquake intensity and the most effect factor to floor rigidity is floor length to width ratio

In this paper , based on the test results of reinforced concrete deep beams , short beams and slender beams under flexture , the behavior and the ultimate moment of deep flexture members are discussed in detail . the calculating formulas for flexture bearing capacity and the design suggestion of reinforeed concrete deep flexural members are also given , and this may provide reference for the revision of p . r . c . design code
