Impact of the changes in reliability index &Beta values calculated by the form method for assessment of the reliability class RC of the analyzed structures
W artykule przedstawiono zagadnienie niezmienniczo艣ci wynik贸w analizy niezawodno艣ci konstrukcji realizowanej metod膮 FORM za pomoc膮 symulacji HMC. Problem zilustrowano na przyk艂adzie analizy d藕wigara stalowego, dla kt贸rego obliczono warto艣ci wska藕nika niezawodno艣ci &betag1) i &Betag2), odpowiednio dla dw贸ch to偶samych funkcji stanu granicznego g1 i g2. Pokazano jak otrzymane r贸偶nice wynik贸w wp艂ywaj膮 na ocen臋 klasy niezawodno艣ci RC analizowanej konstrukcji.The paper presents the problem of the invariance of structural reliability analysis results which have been obtained by applying the FORM method, realized by means of HMC simulation. The problem was illustrated by the example of a steel girder analysis for which reliability index values &beta g1) and &Beta g2) for identical limit state functions g1 and g2, respectively, were calculated. The paper also illustrates how the differences in the results obtained affect the evaluation of the reliability class RC of the analyzed structure
