2 cards from this section. Quick, good the night before a test.
Define the reliability index.
Think about how we quantify safety.
What does the performance function F = C/D represent?
Consider what happens when demand exceeds capacity.
What does the reliability index (β) represent?
Consider what we specifically measure in terms of structure performance.
True or False: A performance function indicates how much demand exceeds capacity.
Think about what the function represents in analysis.
A new skyscraper has a calculated capacity of 5000 kN under live loads and a demand model of 4400 kN. Calculate the performance function F and interpret the safety margin.
Utilize the formula and evaluate the margin.
Calculate the reliability index using a Monte Carlo simulation outcome where mean = 1.5 and standard deviation = 0.3.
Think about the statistical relationship between mean and standard deviation.
