TAILIEUCHUNG - Investigating the effect of column removal on progressive collapse of buildings designed by buckling restrained braced and bending frames

In this study, the behavior of two buildings designed with steel structures Buckling Restrained Braced (BRB) and conventional bending frame was studied to analyze their strengths against progressive collapse. The structures were designed and analyzed in accordance with Iranian regulation No. 2800 for the design of buildings. | Nội dung Text Investigating the effect of column removal on progressive collapse of buildings designed by buckling restrained braced and bending frames Engineering Solid Mechanics 2018 83-88 Contents lists available at GrowingScience Engineering Solid Mechanics homepage esm Investigating the effect of column removal on progressive collapse of buildings designed by buckling restrained braced and bending frames Farzad Akbariniaa Yahya Adinehfarb Hadi Davashic Dariush Jalilid Peyman Beiranvande and Mojtaba Hosseinie a Department of Civil Engineering Imam Khomeini International University Qazvin Iran b Department of Civil Engineering Razi University Kermanshah Iran c Dezful Branch Islamic Azad University Iran d Faculty of Tiran Branch Islamic Azad University Iran e Department of Civil Engineering Lorestan University Khorram abad Iran A R T I C L EI N F O ABSTRACT Article history In this study the behavior of two buildings designed with steel structures Buckling Restrained Received 6 June 2017 Braced BRB and conventional bending frame was studied to analyze their strengths against Accepted 30 September 2017 progressive collapse. The structures were designed and analyzed in accordance with Iranian Available online regulation No. 2800 for the design of buildings. Using nonlinear static pushover analysis the 30 September 2017 Keywords performance of the structure after removal of the center and the corner columns were Progressive collapse investigated and it was demonstrated that removing the corner column provides more critical Buckling restrained braced conditions for the investigated buildings. Furthermore the use of BRB elements provides better Nonlinear static analysis performance for the analyzed buildings due to the ability of BRB in absorbing and dissipating Removing centre and corner more energy induced from the external loading sources like the earthquake. columns 2018 by the authors licensee Growing Science Canada 1.
