Conclusive calculation algorithm for rigid connections with welded box sections.

For the construction of nodes with large welded plates in kind of rectangular profiles, as for example required for racks in power plants, a calculation algorithm is presented. The geometry of a node is determined by a column with two girders and four struts. The assumptions for the distribution of the internal forces in the region of the nodes are shown in kind of figures and formulas for a table calculation program. The calculation algorithm can be checked by given values for a fictitious example. For a practical application it is recommended to distribute the calculation over several sheets in the table calculation program by supplementing this with explaining text. Furthermore, it is also recommended to check the complex geometry of the schemes as shown in figures 1 and 2 after input of the parameters by a plot.
