The direction cosines converged. Task 7

w* = 35.03 + 0.919 x b x 5.25 = 35.03 + 4.82475b p* = 109.19 + 0.394 x b x 12.88 = 109.19 + 5.07472b

0.0381 - 4.99444 x 10-4 x(35.03 + 4.82475b)- 0.873919 x 10-4 x(109.19 + 5.07472b) = 0

Task 8. The reliability index converges with a tolerance level of 0.005.

This simple example outlines the calculation of the underlying risk of a specific design. The design of a structural member is discussed next if the acceptable risk is specified a priori for a specific design criterion or limit state.
