For k = 300 , Ps4 is 2/3 of its upper bound for and

For k = 300 , Ps4 is 2/3 of its upper bound for and

**approximately**1/4 of its upper bound for p = 0.63 . The correlation with respect to materials is not important for the example . This conservative assumption ( without considering ...Page 68

It is seen that

It is seen that

**approximately**30 % of components have reliability indices small enough to be of importance . We thus consider six equivalent midpoint components in each tether . Hence , the system with the two remaining tethers has 12 ...Page 172

For these results , the median value is

For these results , the median value is

**approximately**1.35 MN with the upper and lower bounds varying by 6.6 % about the median . 5.0 THE EFFECT OF MODELING ERROR When the variability in the J - R curve is included dramatic increases in ...### What people are saying - Write a review
