Calculation Method and Temperature Difference in Time History

[ganymede]

Hello there. 1-) I want to calculate my projects in time history using the calculation method. The acceleration values we have are according to the floor classes Z1, Z2, Z3 and Z4. In the new regulation, these classes have changed and their number has increased. For example, which class should I use for ZD? 2-) Is there any disadvantage to using the heat calculation for structures that are not long, apart from increasing the cost?

Hello there; 1. The answer to your question; If it is desired to calculate in a time history according to TBDY, it can be applied by scaling according to TBDY Article 2.5.2. This requires accelerometer sets that are free of ground information (not scaled or modified according to the ground spectrum). The acceleration records you have are probably the acceleration records scaled according to one of the Z1, Z2, Z3, Z4 spectra in the frequency domain or by another method. It is necessary to find the raw form of these acceleration records and make simple scaling (or scaling with another method) according to TBDY 2.5.2 using the spectrum curve calculated according to the ZD soil class. Earthquake acceleration records can be scaled according to the horizontal elastic design spectrum drawn according to the ZD soil class with the simple scaling method described in 2.5.2 and these acceleration records can be used. In other words, the Ground class is used only for scaling the acceleration records. Therefore, you can take action by scaling the acceleration records in your hand according to the new spectrum curve. This facility is available in ideCAD Static. Using the command below you can generate a modal capacity curve using 11 sets of accelerometer records (22 accelerometer records in total).
