I have the following problem in RF‑/FF‑LTB: To analyze the effect on the load application point, I have defined the eccentricity e-z, once positive and once negative. A positive value, which means load application on the lower chord, should be a contribution to the stabilization of the structural system. But this is not the case. What do I have to do?
I have a sandwich panel and would like to use it for structural stabilization of a beam. However, it is only possible to select trapezoidal sheets or purlins. What can I do?
