Question

alpha value =2

Please do part e

Thank you

The "base shear" (B, shear force at the foot of the jacket platform) caused by the impact of a wave of height H is given by cH.. For this platform, the values of c and are: d) c = 10 kN/m' The jacket platform fails when the applied base shear (i.e., demand) exceeds the base shear capacity. The base shear capacity, B, of the jacket platform is a random variable due to uncertainties in the construction process, installation and material properties. Assume that B is a lognormal random variable with mean 7500 kN and standard deviation 1000 kN. What is the failure probability of the platform under the action of H?

Explanation / Answer

c= 10KN/m2

as per relation given p=cH2

for h=10-3

p=10x1000x10-6

and mean base shear capicity decrese in its valye

and heare standaed deviation remains same 1000KN

maen value decrease from 7500

so probability will deacrese
