Hey everyone:
So for typical reinforced concrete member, is there a way to calculate the moment at which plastic hinge will form? I've heard that it is similar to flexural moment, with strain in extreme fibre being 0.003.
Thank you!
Hey everyone:
How do you consider the buckling length of rafter under axial compression? Would it just be the distance between purlins multiplied by a factor of 0.7 ~ 1?
I'm trying to work out the combined action of axial force and bending moment on rafter, however, somehow SpaceGass decides...
Hey everyone:
So I've always been told to assume the rotational restraint factor kr as 1 for the effective length calculation. Then I had a look in AS4100, apparently it is associated with lateral rotation of the member.
My question is how are these restraints provided? In C5.4.2.3, it seems...
Hey everyone:
Let's take 12.7mm low relaxation strand for example, in the PCI code, for effective prestress at transfer, they have adopted 170ksi which roughly equates to (0.75*270)*0.85, assuming the total losses are 15%. However on the second graph, the effective prestress they've taken is...
Hey everyone:
For a typical CU triaxial test, I can't seem to get my head around why the effective failure envelope corresponds to the long-term drained effect for a clay sample.
Let's say the confining stress is Sigma 3 and the deviatoric stress is DeltaSigma, hence total stress sigma1 =...
