What is the factor of safety for Tension Members in LRFD considering the combination U=1.4D
- True
The limit state is the dividing between failure an
- Survival
LRFD is all about allowable loads
- False
Reliability index is the number of times the measure of the variance is to the mean from the origin.
- True
By how many percent is LRFD cheaper for a Tension Member Design compared to ASD if L/D=1
- 6
In ASD the values of the coefficient on the Load Combinations are not based on probabilities.
