AnswerThe stiffness of the bolt does not depend on the strength class and is 210000 N / mm² for most steels. It is therefore possible to select an S235 as the material of the bolt to consider the stiffness of the bolt.
AnswerThe Young's modulus in the state II is not directly output in the deflect calculation.But you can switch to the result window "3.3 Point-by-Scavity Serviceability Design" and filter an FE mesh or grid point for which you want to see the design details. See Figure 01.In the table, select the result row for the "u z, local " deformation.Then, click the [i] button to display the design details for the selected point.In the design details, you can find the intermediate values for the deformation analysis, such as the moment of inertia of the cross-section in state I and state II, the distribution coefficient zeta, and the final cross-section values. See Figure 02.Since these intermediate values are always determined when you open the design details table and are always displayed and temporarily saved for that point, the intermediate values can not be displayed graphically for the designed surface.
For the calculation of members, this Poisson's ratio is irrelevant as it is only used for surfaces and solids.
For an isotropic material model, the Poisson's ratio is fixedly coupled with the modulus of elasticity and the shear modulus. If the Poisson's ratio will be too large and out of the limits, there is no isotropic material behaviour anymore. To avoid the problem, it is recommended to create an orthotropic material for surfaces and solids. For members, it is still necessary to select the isotropic material model. In this case, you can ignore the message.

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.
“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. ”
