Abstract: When designing and building special concentrically braced frames (SCBFs), the common practice is to join the brace to the frame members using a gusset plate that is sized such that the brace buckles in the out-of-plane ...

Abstract: Controlled rocking steel braced frames (CRSBFs) are intended to have a self-centering response that avoids damage to main structural elements. To ensure that all nonlinearity is confined to the intended elements at the ...

Abstract: Controlled rocking steel braced frames (CRSBFs) are being developed as a seismic force resisting system that can be constructed economically to avoid structural damage and residual deformations following an earthquake. In ...

Abstract: For a seismically designed concentrically braced frame with hollow structural sections as braces, the typical connection design consists of a slotted brace that is field welded to a gusset plate. During an earthquake, the ...

Abstract: The assessment of anticipated losses due to damage of both structural and nonstructural components is now recognized to be a key component in the performance-based seismic design or retrofit of buildings. Current ...

Abstract: Controlled rocking systems have been used in numerous structures around the world as a seismic force-resisting system. In a controlled rocking wall system, the wall is allowed to uplift from the foundation during seismic ...

Abstract: The development of models to predict the inelastic behavior of the individual components of a building system at different performance levels is an essential step in performing nonlinear static and dynamic analyses, as ...
