Question

The base shear resistance R of a reinforced concrete building is modeled . a lognonnal random reliable with a mean of 30,000 kips and a coefficie1 of variation of 15 percent If the building U subjected to an earthquake induced base shear demand D of 21000 kip, what is the building probability of failure Assume that the base shear demand D is modeled as a discrete random variable with the PMF plotted in the figure below. What is the building probability of failure It is known that the building has failed. What is the probability that the building was subjected to a base shear demand of 25,000 kip

Explanation / Answer

soln-

(a) 0.09 is probability dat the building will fail

(b)0.4 is the probability of failure

(c) 0.2 is the probabilty
