What should i do next to calculate the reliability using first order reliability method?

x=load;
l=lengthofbeam;
b=base;
d=distance;
h=widthofbeam;
y=yieldstrength;
functions [beta,pf] = firstorderreliabilitymethod;
g=y - ((x*l*l/8)*(d/2)/(b*h*h*h/12));
beta=3;
designpoint=(0.5,0.5);

hi nazran,

The procedure of the FORM is briefly summarized below.

1) Transform the original random variables from X-space to U-space by Rosenblatt transformation.

2) Search the MPP in U-space and calculate the reliability index b .

3) Calculate reliability R = F (b ) .

here is the documentation for calculating reliability using FORM
