The reliability of the shear failure tend to be evaluated regarding the shear force developed at the yielding mechanism as the load, although the seismic reliability of structure is evaluated to the seismic load. The reliability of the shear failure must be evaluated to the seismic load, because it is impossible to compare each other between the reliability indices to the different loads. In this paper, the approximate equation for the probability of shear failure of reinforced concrete building to the seismic load during the reference period is presented. The probability of shear failure is evaluated in explicit form utilizing Cornell's method. By the dynamic magnification effect, the response shear force of column increases over the force developed at the overall yield mechanism. In order to take that effect into account, the increment of shear force over the existing shear force at the mechanism is assumed to be proportional to the peak ground acceleration. The exceeding probability of the peak ground acceleration is approximated by Frechet distribution.
