Determination of Partial Coefficients of Structural Reliability Design

Based on the geometrical meaning of the reliability index b and the basic concept of partial coefficients, the calculation method for the partial coefficient in the structure limit states design equation is discussed under the objective reliability index bnom by constructing a virtual limit state camber. Meanwhile, the calculation method for the partial coefficient under an ordinary distribution of correlated variables is also discussed. A numerical example shows the effectiveness of the methods proposed.
