8A. ANALYSIS Part 1: NEW BUILDINGS

CHAPTER 8A 'ANALYSIS' 68 2.1 Combinations for Wind - Snow 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 generation of loads and scenarios (see Chapter 6) 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 static wind and snow scenarios, with the earthquake scenario active you select the "Combinations" and "Predefined 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 wind and snow scenarios' coefficients are automatically populated, providing a complete file of combinations of all the study loads. Select to save it to use it for sizing.
