Optimum Design to Resist Earthquakes
Publication: Journal of the Engineering Mechanics Division
Volume 105, Issue 1
Abstract
Optimization is taken as minimization of the sum of expected present values of initial costs (including engineering services and construction) and (magnified) losses due to a structure's entrance into limit states. Dead, live, and seismic loads are considered. Attention is given to optimum repair and reconstruction policies; this problem is formally identical with optimization of resource allocation to research and development. Expenditures in engineering services are taken here as a constant. Except for uncertainty about maximum possible seismic intensity, uncertainties call for approximately multiplicative safety factors. Under some conditions design live loads under earthquake exceed that under gravity alone.
