Abstract
This paper presents the fragility analysis of the NPP Communication bridge support frame resistance due to extreme wind loads. The aim of the contribution is the reliability analysis of the structural bracing system of the bridge. The wind load was determined on base of the fluid analysis using ANSYS-FLUENT program. On the example of the steel bridge between two NPP buildings with the various forms of the bracing systems is considered the efficiency of the structural system. The beam and the link elements from ANSYS library were used. The methodology for proving capacity reserve of the structural resistance by non-linear analysis considering the uncertainty of the input parameters is described here. The advantages of the utilization the LHS method to analyze the safety and reliability of the structures is presented.
