Calibration of Seismic Reliability Models distributions of the behavior indeces of different structures, and a bayesian formulation is adopted for updating prior distributions of means and variances of those indeces in the light of uncertain observations about values taken by them in real structures responding to earthquakes.

Computational Experience with Vector Optimization Techniques for Structural Systems design problems engineers are confronted with alternatives that are conflicting in nature. For these problems, where the quality of a design is evaluated using several competing criteria, vector optimization (also called multiobjective, multicriterion or Pareto optimization) should be used.

Expectation Ratio Versus Probabilityral system to another, it is advocated that the design of structural systems be based, instead, on the consideration of the ratio of the expectation of benefits to be gained by rendering a system safer to the consequent increase in its cost.

Reliability of Daniels Systems with Local Load Sharing Subject to Random Time Dependent Inputs consistent with the stress distribution observed in composite and fiber-reinforced materials (9). Most studies on the reliability of Daniels systems involve elementary loading conditions, e.g, time-invariant and monotonic loads (8,10). Dynamic loads began to be considered recently for Daniels systems with the equal load sharing rule (1,2,3,4).

Optimal Allocation of Available Resources to Improve the Reliability of Building Systemst environment is tackled. Following other recent researches [1–3], three alternative “types” of retrofitting (upgrading intervention) of known cost per unit volume are considered; it is also assumed that the “vulnerability” of each building, the “losses” under an earthquake of given magnitude and th

Life Expectancy Assessment of Structural Systemss well as incomplete knowledge of their characteristics. In this a paper, a methodology for structural life expectancy is suggested. The methodology is based on structural reliability, theory of extremes, a plate wastage model, and system analysis. Example applications using marine structures are di
