Sds and Sd1 values do not match for ZF ground

[cagdaserel]

Good work everyone. I have attached the calculated values, spectrum and idecad file for ZF ground. When we calculated the spectrum according to the data below and entered the idecade, I entered the Ss and S1 values, Ta and Tb values. But since I cannot enter the Fs and F1 values in idecad, when I enter the spectrum I calculated with the data below, idecad finds different sds and sd1 results. What I'm wondering here is, why can't we find the same results, with which values or formulas or according to what spectrum they are getting? I would be glad if you inform me. Good luck with.

Hello there; For the ZF type, you have to enter the spectrum from the outside. You do not have a connection with parameters such as Fs F1 S1 Sds in the analysis settings. These parameters are calculated automatically according to the parameters taken from the map in other soil types and are compatible with the manual calculation. However, in ZF type, the program uses the spectrum data you entered directly in the analysis, so do not interfere with the S1, Ss parameters. Because they will not be used anywhere in the account anyway. Only we are currently printing the report, this will be corrected. Until this process, you should edit the Ss, S1 data from the report to be your own correct data. At the same time, these parameters are taken from the analysis settings wizard and work is carried out for the program to calculate automatically. In the coming versions, your work will be made easier for the spectrum generation for the ZF type. Thank you for your understanding. Why the program does not take Fs and F1 values because in TBDY 2018 Table 2.1 it is written that Fs and F1 should be taken from the special analysis for ZF. For this reason, the program does the following solution: It takes the spectrum obtained directly from the user as a result of a special process that requires consultation, and does not create a spectrum itself by applying intermediate processes. Good work.

Hello, good work, I'm having the same problem. .

The answer is valid for you. Remove the Sds and Sd1 values in the report, add the values in your geotechnical report used when calculating the spectrum, since you entered the spectrum from outside. To add the correct ZF spectrum to the program, follow the instructions in the attached pdf.
