IMPAβ: Incremental Modal Pushover Analysis for Bridges

open access: yesApplied Sciences, 2020
In the present study, the incremental modal pushover analysis (IMPA), a pushover-based approach already proposed and applied to buildings by the same authors, was revised and proposed for bridges (IMPAβ). Pushover analysis considers the effects of higher

Progressive Collapse Analysis of Moments Resisting Frames with Cruciform Columns Semi-Buried in Concrete [PDF]

open access: yesمجله مدل سازی در مهندسی, 2021
Local damage caused by the removal of one or more elements in structures lead to progressive collapse and results in partly damage to the structure, increasing damage rate and total collapse of the structure.
