FBE HingeRadau Sections

Post by apapaso »

Hello everybody!

As I understand, FB elements with HingeRadau integration method have 5 integration points and 6 output sections.
What is the location of each output section?

I 'll try to be more specific:

Sections 1&6 correspond to the ends I&J of the element
Sections 2&5 correspond to the integration points at a distance of 8/3Lp from the ends
Sections 3&4 seem to be located even further from the ends. I worked out their location as following:

L=3.1542*βi-0.8448*bj+0.2113 , where βi, βj the ratio Lpi/L, Lpj/L. So the location of each one depends on both Lpi and Lpj.

What is the meaning of these sections? Are they integration points? Are they imposing a limit to the Lp? (for Lp>0.125L sections 3&4 cross over into the other half of the beam)
