Abstract
In order to investigate accuracy of shear ultimate strength formulas, test results of 47 short span R/C specimens were chosen from previously published papers. Ohno & Arakawa's formula and two AIJ design guidelines were adopted for evaluating the test results. As results of comparison between the test results and the calculations, the followings were found: the formula in the AIJ design guideline based on ultimate strength concept had the best precision in these three formulas though had problems in verification of bond and estimation of shear reinforcing effect; Ohno & Arakawa's formula is practical for applying to the short span beams from the viewpoint of safety evaluation; and the formula in the AIJ design guideline based on inelastic displacement concept is inappropriate for the short span beams.
