Get parameters from map

When the button is pressed to read parameters from the AFAD Map, the program runs a 3-step wizard. In the wizard, the interface to select a point from the map for earthquake ground motion level, ground class and design spectrum is displayed. The parameters are read automatically when the wizard is terminated.

Spectrum curve

Image Removed

Image Added

The spectrum curve resulting from the settings is shown.

Function name

The name of the spectrum function.

Spectrum multiplier

Factor of spectrum function.

Ss

0.2 sec spectral acceleration of spectrum function.

SDS

Image Added

Design earthquake spectral response acceleration parameter at short period.

S1

1 sec spectral acceleration of spectrum function.

SD1

Image Added

Design earthquake spectral response acceleration parameter at 1-s period.

Fs

Image Added

Short-Period Site Coefficient.

Fs

Image Added

Long-Period Site Coefficient.

 Soil type

Soil type that determine the spectrum curve are determined according to the ground on which the building is located. The spectrum curve is renewed according to the selected soil type. It is one of the parameters selected in 2018 TDY wizard for analysis settings, and this row is automatically refreshed when the wizard is used.

Custom

It is used to define any curve other than the spectrum curve determined according to the soil type in the earthquake code.

You can mark this line and click the Define button to make the definition you want.

Lambda coeff.

The Lambda coefficient, which is calculated automatically depending on the earthquake parameters DD2 and DD3 and used in limiting the relative floor displacements, is shown in this line for information purposes.
