METHOD FOR EVALUATING PROOF STRESS OF REINFORCED CONCRETE STRUCTURE AND PROOF STRESS EVALUATION PROGRAM

摘要

PROBLEM TO BE SOLVED: To provide a proof stress evaluation method and a proof stress evaluation program which can solve problems of an existing technique by individually estimating progresses of corrosion of a main reinforcement and a shearing reinforcement bar and then evaluating the proof stress of the reinforced concrete structure with the shearing proof stress and the bending proof stress of the reinforced concrete structure taken into consideration.;SOLUTION: The method for evaluating the proof stress of a reinforced concrete structure according to the present application includes: a first corrosion amount calculation step; a second corrosion amount calculation step; a first remaining reinforcing bar amount calculation step; a second remaining reinforcing bar amount calculation step; a shearing proof stress calculation step; a bending proof stress calculation step; a bending shearing proof stress ratio calculation step; and a proof stress evaluation step. In the bending shearing proof stress ratio calculation step, the bending shearing proof stress ratio of the reinforced concrete is determined based on the shearing proof stress and the bending proof stress of the reinforced concrete. In the proof stress evaluation step, the proof stress of the reinforced concrete structure is determined by comparing the bending shearing proof stress ratio of the reinforced concrete with a threshold value.;SELECTED DRAWING: Figure 7;COPYRIGHT: (C)2017,JPO&INPIT
