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?

Answer

You can calculate the rotational restraint manually or by using a program. Then, enter the resulting value in the 'Settings' table as stiffness C_D (see the figure). For this, set the type of rotational restraint to 'Define Manually'.
