EXAMPLE 3. NON-STANDARD STUDY METAL CONSTRUCTION

EXAMPLE 3: 'DESIGN OF A METAL STRUCTURE' 42 In cases where Dynamic analysis is required, if you select "Nodes" for the corresponding dynamic scenario and "open" the springs ("Yes"), then you can use the dynamic combinations for the dimensioning of the foundation. With the EC8 Dynamic script selected, the " Load " command opens the following dialog box: where, for each charge of the scenario you created (left column), you assign one charge (LC) from the ones you created. • select the value 1.00 for LC1 (after first selecting the category "Permanent Loads" - G(1), which is coloured blue) and 1.00 for LC2 (after first selecting the category "Mobile Loads" - Q(2), which is coloured blue). • The "+" next to the charge category indicates that there is a charge participation for that particular charge. to update the script and register the changes. The program automatically populates the unit in the corresponding charge, so any modification is, again, optional. In the Static snow and wind scenarios the respective loads are included in the static analysis without including the permanent LC1 and mobile LC2 , since they have been taken into account in the seismic analyses.
