Evaluation of reliability of beam and suspension combined structures
Abstract: There is presented a technique of evaluating reliability of steel beam and suspension structures based on the idea of the direct assessment: emergency situations for a probabilistic design are considered on grounds of the nonlinear design of a structure. A direct probabilistic estimation was done with the use of the method of statistical tests in the form of modified stratified retrievals. The statistical record of the development of plastic deformations was done on the base of the suggested criterion of small-scale plastic deformations. The general reliability of the constructive system is estimated by the criterion of a material failure. The suggested technique is illustrated by considering a single-span suspension system with vertical suspenders. On the base of the failure criteria formed there was suggested a classification of technical states of beam and suspension structures.
Keywords: structure, core, flexible cord, estimation, strain, deformation, plastics, probability.
