Calculate Time Period Using ASCE 7

Learn how to set the seismic time period (Ta) in ETABS based on Section 12.8.2 of the ASCE 7-22 code. In this video, we explain the approximate fundamental period calculation using the Ct and x coefficients, and how to apply the Cu × Ta limit.

This step is essential before running your analysis. We also discuss the difference between using Ta and the program-calculated period T, and when to adjust the period based on CuTa.
