I have a 3D model and try to split it up into "walls" and "surfaces" with the Building Model and to calculate them separately. However, my structural system becomes unstable then. What can be the reason?
I received an error message “Surface of incompatible type... (Surface in upper plane of building story must be of ‘Load transfer’ type)” when running the calculation. What is the reason?
I would like to perform punching design of a floor slab. I have selected nodes for the design, but they are marked as invalid. Where did I make a mistake?
How can I teach the program to automatically increase the longitudinal reinforcement when calculating the deflection of slabs in order to meet the preset deflection?
I applied a unit load of 1 kN/m² to the top slab of a 3D model consisting of three identical floors to determine the spring stiffness of the supports from axial forces and deformations of the columns for 2D modeling of the slabs. Despite deactivating the self-weight of the structure, the column axial forces are redistributed story by story. Is it possible to deactivate this effect?
When using line releases, I cannot understand the failure definition. To which axis do the nonlinearities "Fixed if positive vz" and "Fixed if negative vz" refer?
I would like to enter a reinforced concrete beam that is wider at the bottom side than at the top side. Do I have to define two separate beams and couple them? Or is there a special type of cross-section?
I am designing a combined structure made of timber materials with different creeping parameters. How can I perform the serviceability limit state design according to EN 1995‑1‑1?
We want to reinforce a floor slab of a round vessel radially or tangentially.Is there a way to calculate not an orthogonal reinforcement, but a radial or tangential reinforcement?
A high-rise steel structure has several stories and is stiffened by bracings in all stories.However, the first story is made of reinforced concrete. Therefore, the horizontal bracing should work via this concrete slab. How can I model this rigidly fixed concrete slab in RSTAB?
Why is it not possible to specify a "favorably acting soil contact stress" at a wall corner or wall end for punching shear design of a floor slab? Where can I find the input option for this?
For the design of biaxially stressed slabs in RF‑CONCRETE Surfaces, I obtain minimum reinforcement in both slab directions. Is it possible to set in the add-on module where the minimum reinforcement should be applied?
Can I create a punching shear reinforcement in RF‑FOUNDATION Pro to increase the punching shear resistance of a foundation slab? Or is it possible to arrange vertical stirrup reinforcement in RF‑FOUNDATION Pro?
