Packaged Videos of the Collapse of RC SMF Structures
The following files include packaged videos, which are animations of the analytical collapse predictions completed as part of this research. Please feel free to use these videos for educational purposes, but please do so with proper reference to this research.
The collapse videos show the progression of plastic hinging through the nonlinear dynamic analyses. The following figure (from Goulet and Haselton et al. 2007) shows the final collapse mechanisms for a 4-story RC SMF subjected to many ground motions.
The above figure shows the final damage mechanisms at collapse, but the videos show the progression of plastic hinging. The following legend explains the meaning of the blue and red circles in the videos. As the circle grows, this indicates the progression of plastic hinging; when the circle turns red, this indicated that the plastic hinge has reached the "capping point" where strain softening (rebar buckling) occurs.
Structural response animation videos are available in .wmv file format for the following two ground motions at three intensity levels. Note that the PowerPoint file package below includes these six .wmv files, as well as summary information.
Superstition Hills (M=6.7) - El Centro Station:
Loma Prieta (M=6.9) - Gilroy Array #3 Station:
- Spectral acceleration: 40% of collapse level (near MCE on average) [link]
- Spectral acceleration: 102% of collapse level [link]
- Spectral acceleration: 200% of collapse level (note some numerical instability at end of record, but this is after dynamic instability and large displacements have already occurred.) [link]
The full package of collapse animation files (both PowerPoint and .wmv) is available [here].
