The aim of this study is to seek, on the results of the preceding study, necessary and sufficient conditions of the optimum design loads of public buildings and facilities whose functions are important in cases of disasters or reconstruction phases. This paper builds up eight hypotheses and assumptions in order to attain the goal. The fundamental hypothesis and assumption areas follows; 1) the economically optimum design load condition should, under the financial reitriction, maximize the total estimated utility (E) which is composed of usual utilitites (u), utility in disasters (U(x)) and damage caused by the own distrunction (-D(x)). The total utility function is denoted by (2.1) and this hypothesis by (2.9). 2) the utility in disasters (U(x)) depends on the quantity of of distroied ordinary buildings and structures, the damage (D(x)) depends on the rest, which are dealed in the preceding study. The obtained results are as follows; The optimum pesiign loads are given by the equilibrium formula (2.9), (2.12), …(2.16), which prove thae that they should depend on social, economical, technical and natural conditions in the area.
