Seismic Behaviour of Steel Frame with Different Bracings Subjected to Mainshock and Aftershock Sequences
https://orcid.org/http://orcid.org/0000-0002-4378-180X
The recent 2023 Turkey earthquake and many past seismic events demonstrated that aftershocks could potentially collapse the structure, which may not collapse during the mainshock. However, design philosophies are based on the peak earthquake force. Hence understanding the performance of structures subjected to mainshock and aftershock earthquake sequences is crucial. The effect of the earthquake sequences is well-studied for reinforced concrete buildings, but more work is needed for steel structures. Hence, this study evaluates the behaviour of a 12-story frame with various bracing, including V, inverted-V (IV), K and inverted-K (IK). The duration of the rest time between the mainshock and aftershock is defined, and nonlinear dynamic analysis is performed using OpenSees. The performance of the frame with various bracing is compared by varying the seismic intensity and soil condition. The findings can contribute to the development of effective seismic design strategies.
