How to compute the torsional amplification factor (Ax) using ETABS software (Lec16)
This video explains the source of the inherent and accidental torsion of buildings according to ASCE. It also shows how to obtain the center of masse and rigidity, and how to compute the torsional amplification factor (Ax).
Upon the request of many, you can download now the excel sheets from the link below:

really appreciate !
In 6:58 If different between cm and cr exceed 5% what will we do?
Hi Tarek, you computed the Ax based from static Ey (drift) and made the eccentricity overwrite correction in dynamic response spectrum RSy... Is that for demo only coz it should be an Ax computed from RSy (drift). Kindly clarify this... Thnx

Hello there, Yes, you're correct; the calculation in the video was done for demonstration purposes only. We should indeed compute Ax using the Response Spectrum Analysis (RSA) method and make the eccentricity overwrite correction within the RSA load case. I apologize for any confusion this may have caused. I'm currently working on a comprehensive video that explains the process of computing Ax from RSA. There are several options available, and I want to ensure a thorough explanation. It's not a straightforward topic to cover in a brief comment. Stay tuned for the upcoming video where I'll provide a detailed walkthrough of the Ax computation using the RSA method.
when you are applying eccentricity in +x and -x how do you go about it when you only defind RSA _x in only one direction
