PROBLEM TO BE SOLVED: To provide a method for performing material design of an impact-resistant structure made using concrete so as to reliably suppress rear-surface exfoliation and penetration, and an impact-resistant structure.SOLUTION: In a material design method for an impact-resistant structure made using concrete, tensile softening start point stress intensity and ultimate tensile strain or tensile softening area strain amounts in tensile softening characteristics of concrete are used as parameters, a combination of two parameters in which damage to a concrete member due to an impact load becomes smaller is derived, and concrete to be the combination of two parameters is used. |
