What is meant by Eccentric beam loads?
"Eccentric beam loads" refer to loads acting on a beam that do not apply at the centroid or the middle of the cross-section but at a point outside the central axis of the beam. These loads generate additional torsional and shear stresses in the beam along with the usual bending stresses. This requires detailed analysis and specific methods for calculating the stresses and deformations.
Typical software functions in the area of "Eccentric Beam Loads":
-
Load Modeling:
- Definition and application of eccentric loads on structural elements.
- Input of load positions relative to the beam axis.
-
Stress and Deformation Analysis:
- Calculation of stresses and deformations caused by eccentric loads.
- Analysis of bending moments, torsional moments, and shear forces.
-
Finite Element Analysis (FEA):
- Use of the finite element method for detailed modeling and analysis of structures with eccentric loads.
- Simulation of real load distribution and deformation behavior.
-
Material and Cross-Section Optimization:
- Optimization of material selection and beam cross-sections to withstand the loads.
- Adjustment of dimensions to minimize deformation and stresses.
-
Creation of Load Diagrams:
- Visualization of load distribution along the beam.
- Representation of resulting stresses and deformations through diagrams and graphs.
-
Integration with CAD Systems:
- Import and export of structural data and load cases between CAD and analysis software.
- Automatic transfer of geometry and load information.
Examples of “Eccentric Beam Loads”:
-
Balconies and Canopies:
- Loads caused by people or furniture acting at the edges of balconies or canopies.
-
Cranes and Lifting Equipment:
- Eccentric loads generated by lifted loads on crane arms or lifting beams.
-
Facades and Overhangs:
- Wind loads or self-weight acting eccentrically on facade structures or architectural overhangs.
-
Bridge Construction:
- Traffic loads acting on bridge girders not at the center but at the sides.
