Interstorey Drifts (ASCE 41-23 & NTC)

Herein the results of the interstorey drifts checks for columns and walls are presented (this check applies to ASCE 41-23 and NTC). Users may select, for which Limit State to view the results, as well as the display criteria, which include the determination of the analysis and the floor. It is noted that only the walls controlled by shear are checked according to the ASCE 41-23 and only the limit states of Damage Limitation and Operational Level for columns and walls are checked according to the NTC. In addition, in the drop-down menu for the analysis selection apart from the executed analyses there is an option called Critical Analysis, which is the envelope of the results of all the analyses. The elements that have exceeded the Code defined relative drift are marked with red both in the table view and the 3D view format, whereas different visualisation options are available. For instance users may select to display the members’ performance ratios or each member’s critical analysis on the 3D plot, or to display the elements with different colours, depending on the value of their performance ratio for the selected limit state.
