Example and screenshotsĪ few examples are include with the package. The exception are the internal forces for which the following convention is used: 4. The output follows the coordinate systems which means that the displacements and the reactions are in global axes and member end forces in local axes. For example, if newtons (N) and meters (m) are required as output, the input units are N, Nm, N/m 2, m 4. The units must be the same through all the input data. The local axes are always from the near node to the far node.Įxamples of the usage are provided with the package. The following images show the used coordinate systems and the conventions for the member forces. The current version is 1.0.5 with support for multiple load cases!įor the nodes and the members, care must be taken for the axes. Ocframe can be downloaded from the sourceforge project website. The structure with displacements can also be plotted. A plotting function is provided to plot the frame with node and member numbers. The package will provide the displacements, the reaction forces and the member end forces. Currently the basic needs are supported but this will change in the future.įor the moment all sorts of member loads and nodal loads are supported.
