2nd order nonlinear - Compression only element
Problem definition
Calculate the reaction forces for the compression only structure shown below.
Assumptions
All elements are constant and equal EA, and can resist only compressive forces
Key results
Under the applied loading the element on the left becomes inactive, therefore all applied loading is resisted by the support on the right.
| Result | Theoretical formula | Theoretical value | Solver value |
|---|---|---|---|
| LHS Reaction | 0 | 0 | 0 |
| RHS Reaction | -P | -1000 | -1000 |
Conclusion
An exact match is observed between the values reported by the solver and the theoretical values.
