Hybrid Approach to the First Order Reliability Method in the Reliability Analysis of a Spatial Structure

The objective of the article involves presenting two approaches to structure reliability analysis. primary research method was First Order Reliability Method (FORM). Hasofer–Lind index ? in conjunction with transformation FORM adopted as measure reliability. first proposal combining NUMPRESS software non-commercial KRATA program. In this case, implicit form random variables function created. Limit state symbolically given standard math notation a basic and external variables. second analysis proposed hybrid approach enabling introduction explicit forms limit functions To create descriptions formula, neural networks were used our own original FEM module. combination conventional computing can be seen system. implemented into software. values for different mathematical model determined. allowed us obtain similar results from reference method.
