Book excerpt: The objective of this research was to develop reliability-based design methods for reinforced protective concrete structures. The analysis and design methods in the Air Force Protective Construction Design Manual (PCDM) provided the nominal (deterministic) methods that were used to perform probabilistic response analyses and the reliability assessments. One of the key objectives of this effort was to develop simplified rehability-based design methods, in the form of reliability-based design factors (RBDFs), that can be used by designers who are unfamiliar with probabilistic methods. Research was conducted in five fundamental areas: (1) airblast and aboveground structure response; (2) groundshock and belowground structure response; (3) fragmentation effects; (4) projectile penetration; (5) protective structure systems reliability. In each of the areas, emphasis was on reinforced concrete structures; however, the load uncertainty analyses are applicable to structures of any materials. In s instances we found significant biases in the PCDM models. In those cases where we found significant biases that could not be corrected without changes to the fundamental approach, RBDFs were not developed. Over twenty tables of RBDFs were developed for use with the PCDM procedures. Conventional Weapon Effects, Fragmentation, Airblast, Groundshock, Penetration, Reliability.
