Heuristic Operator for Reliability Assessment of Frame Structures

In structural design of steel frames, in order to achieve proper safety, the effect uncertainties and loading parameters structure must be considered. This approach is obtained by defining a reliability index. this study, Modified Dolphin Monitoring (MDM) operator was used evaluate index three well-known frame structures based on Hasofer-Lind method. The evaluated using EVPS VPS algorithms with considering MDM them. constraint last story drift considered as limit state function. random variables consist external loads, modulus elasticity, moment inertia cross-sectional areas. According number evaluations function, results show efficiency method comparison Monte Carlo simulation Also, values most probable point (MPP) are examined.
