2nd order nonlinear - Compression only element

Problem definition

Calculate the reaction forces for the compression only structure shown below.


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


An exact match is observed between the values reported by the solver and the theoretical values.
