There is a difference between the following eccentricities:
In RFEM and RSTAB, a member length corresponds to the distance between two nodes, which is defined by the line of a member. In the case of cross-section connections or downstand beams, the reality is only modelled approximately. By using member eccentricities, it is possible to connect members eccentrically by specific member end sections. For example, you can thus reduce design moments at beams for the frames with large column sections. The member eccentricities are taken into account by a transformation of the degrees of freedom in the local element stiffness matrix.
A plane in the neutral axis of a surface represents the reference surface of thickness. It is applied in equal proportions on both sides of this 'central plane'. By specifying the eccentricity e<sub>z</sub>, it is possible to arrange an offset of height for the surface. In this way, you can achieve the adjacent surfaces with different thickness to have a uniform top or bottom edge.
Depending on stiffness, mass, and damping, structures react differently to wind action.
- How can I model a timber-concrete composite floor?
- I would like to calculate and design "temporary structures." What do I need for this?
- Which programs can I use to calculate and design power plants?
- What is the best way to consider steel fiber reinforced concrete with the structural analysis program RFEM?
- I would expect the results from my load combination (CO) set to a linear analysis to equal the summation of the results from my load cases (LC) also set to a linear analysis. Why do the results not match?
- Are the Dlubal Software programs suitable for the analysis and design of hydraulic steel structures?
- How do I display the nodal displacements graphically?
- In connection with the calculation according to the large deformation analysis, I get significantly smaller deformations than for the calculation according to the linear static or second-order analysis. How is this possible?
