Structural Reliability Analysis And Optimization Algorithms

At first, this paper reviews the devolopmeat of structural reliability, points out it'sreseaxch derection in the fUtaxe. Several necessaxy concept Of structural reliability areintroduced.Secondly through discussing the first-order second-moment method which is widelyaPplied in engeering, the aothor linds out it's advantages and disadvatages. Also, thepaper evaluates the imProvemelit which researchers have conduct to date.Finally to remove the disadvantages above-melltioned, this paper preseats the op-timization model of calculating the structural reliability index, B, under related normalrandom varables. Applying the-knowledge of optiwhation programming, the authorpresented three methods to calculate the index, g. Several exaInPles are given to provethe validity of thOse thIee algorithms.Structural reliability index,the Lagragian method；the Gradientprojection method,the augmented Lagragian method．...
