Finally, depending on the seismic category of the building, restrictions on the choice of the Structural System and a restriction on the maximum height of the building are specified. The next section of the parameters concerns Design Response Spectrum according to par. 9.4.5 of SBC 301 The application automatically calculates the values T0 and Ts based on the previously defined values S1 and Ss. Of course there is also the possibility of modification by the designer. ATTENTION! If any change is made to these values either automatically or by the designer in order to update the spectrum you must press the Pressing the button the dialog box with the design response range per direction appears
