Ahs. Ang et D. Deleon, DETERMINATION OF OPTIMAL TARGET RELIABILITIES FOR DESIGN AND UPGRADING OF STRUCTURES, Structural safety, 19(1), 1997, pp. 91-103
A systematic approach is proposed for formulating risk-based cost-effe
ctive criteria for the design and upgrading of structures with special
reference to earthquake protection. Target reliabilities (or acceptab
le risks) for damage control and life safety are determined on the bas
is of minimum expected life-cycle cost and from which risk-consistent
criteria for design or upgrading are developed. The approach is illust
rated for a specific class of reinforced concrete buildings in Mexico
