As a general quality characteristic with comprehensive feature, the Aircraft Structure Operational Integrity (ASOI) is the basis for aircraft structure to exert its operational applicability and effectiveness. The ASOI includes 6 characteristics，such as durability, supportability, safety, structural capability, survivability and recoverability. And even the same structural design techniques may have different effects on the 6 characteristics. In order to improve the ASOI, the development requirements of aircraft structural strength are discussed from the perspective of 6 characteristics of ASOI, based on the analysis of ASOI meaning and aircraft combat characteristics. In addition, the influence of typical structural design techniques on ASOI is also analyzed.
