2. Benchmark solution

2.1. Calculation method used for the reference solution

Analytical solution:

• Normal effort in each of the bars \(\mathrm{AC}\) and \(\mathrm{BD}\): \(N=\rho .\mathrm{L.A.g}/2\)

• Move \({U}_{y}\) in \(C\) and \(D\): \({U}_{y}\mathrm{=}\mathit{NL}\mathrm{/}\mathit{ES}\)

2.2. Benchmark results

• Normal effort in bars \(\mathrm{AC}\) and \(\mathrm{BD}\): \(N={4.10}^{5}N\)

• trips to \(C\) and \(D\): \({U}_{y}=2{10}^{-5}m\)

2.3. Uncertainty about the solution

Analytical solution.
