8B. ANALYSIS PART 2

CHAPTER 8B 'ANALYSIS' 58 An automatic procedure was therefore created in the program, during which the designer first selects as active the scenario on the basis of which analysis scenarios corresponding to the basic seismic classes will be automatically reproduced, i.e. scenarios which will have the same parameters as the basic scenario and with the only difference from it being the spectral acceleration, which varies depending on the seismic class. The dialog box for this function is opened by pressing the "Seismic Class" button Warning: before using the command you must ensure that the scenario is active, which will form the basis of the automatic generation of the scenarios for the basic seismic classes that we will see later. The following dialog box appears in its original form The red box shows the name of the scenario that will be the basis for the creation of the scenarios. The function of the dialogue window is twofold: Automatic and " manual ". • Let's first look at the Automatic mode: You choose for which basic seismic class(es) you want to create scenarios by checking the corresponding options (one, several or all)
