EXAMPLE 3. NON-STANDARD STUDY METAL CONSTRUCTION

EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 50 The same is achieved by selecting the "Predefined Combinations" command, as the program will enter the combinations related to the active analysis scenario The predefined combinations of the "running" scenarios of the analysis are automatically entered by the program. In addition to the predefined combinations, the designer has the possibility to create his own combination files, either by modifying the predefined ones, or by deleting all of them "Delete All" and entering his own values. The "Load Set Combinations" tool works like an Excel page offering copy, total delete capabilities in the classic ways, Ctrl+C, Ctrl+V, Shift and right-click. The predefined combinations refer to seismic scenarios. To create combinations of scenarios that do not contain an earthquake, both automatic and manual modes are available. The automatic mode assumes that the automatic procedure for the calculation and distribution of wind and snow loads, the automatic creation of the loads and combinations, as in the example above, has been carried out beforehand.
