  • Answer

    The determination of the direction is always determined by the line release axis system and by the position of the cut-free object. You can activate the display of the line-release axis system in the Project navigator - Display under Model -> Line releases (see Figure 1).

    To specify the direction for the determination of nonlinearities, it is important to know, how the released object moves relative to the line release axis system of the original element.
    In Figure 2, surface 2 is defined as a released object with the line release uz if vz is defined as negative. The loading shown in FIGS. 1 and 2 would move the released surface 2 counter to the z-axis of the line release axis system. Thus, the line release would not be effective for these loads, i.e. surfaces 1 and 2 would be firmly connected.

First Steps

First steps

We provide hints and tips to help you get started with the main programs RFEM and RSTAB.

Wind Simulation & Wind Load Generation

With the stand-alone program RWIND Simulation, wind flows around simple or complex structures can be simulated by means of a digital wind tunnel.

The generated wind loads acting on these objects can be imported to RFEM or RSTAB.

Your support is by far the best

“Thank you for the valuable information.

I would like to pay a compliment to your support team. I am always impressed how quickly and professionally the questions are answered. I have used a lot of software with a support contract in the field of structural analysis, but your support is by far the best. ”
