EXAMPLE 4. METAL STUDY CONSTRUCTION WITH 3D DWG

EXAMPLE: 'DESIGN OF METAL CONSTRUCTION' 46 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 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. Subject to the above conditions, it is possible to create the wind and snow combinations automatically using the command. So, after first running the earthquake scenario and all the static wind and snow scenarios, with the earthquake scenario active, select the "Combinations" command. The combinations of the active scenario are automatically filled in. To automatically create the other combinations (wind and snow) press the button . The coefficients of the wind and snow scenarios are automatically filled in, providing a complete file of combinations of all the study loads.
