Is the preset crack width of, for example, wk = 0.3 mm also designed for primary cracks? According to the manual, the average strain is considered. Does this ensure that the primary crack does not exceed the value wk = 0.3 mm?
I am designing a set of members with a uniform, double-symmetric cross-section and I get the warning "Non-designable: ER051 Moment about z-axis on asymmetric cross-section, taper, or set of members". Why?
Which theoretical approaches are used in RF‑/FOUNDATION Pro for pocket foundations with rough bucket sides to divide the forces and moments and carry out the reinforcement layout?
The RF‑/DYNAM Pro add-on module has the parameters "Modal mass", "Participation factor", and "Equivalent mass". The manual contains the formulas, but an explanation and hints on how to use them would also be helpful.
In RF‑CONCRETE Surfaces, I get non-designable situations at some locations. Note 5 is displayed: "Allowable compressive stress of concrete in strut direction exceeded."
