Seismic Response of Braced Steel Frames with Shape Memory Alloy and Mega Bracing Systems
Steel bracing members are widely used in steel structures to reduce lateral displacement and dissipate energy during earthquake motions. Concentric steel bracing provide an excellent approach for strengthening and stiffening steel buildings. Using these braces the designer can hardly adjust the stiffness together with ductility as needed because of buckling of braces in compression. In this stu...
متن کاملThe Effect of Frame Geometry on the Seismic Response of Self-Centering Concentrically- Braced Frames
Conventional concentrically-braced frame (CBF) systems have limited drift capacity before brace buckling and related damage leads to deterioration in strength and stiffness. Self-centering concentrically-braced frame (SC-CBF) systems have been developed to increase drift capacity prior to initiation of damage and minimize residual drift. SC-CBFs differ from conventional CBFs in that the SC-CBF ...
متن کاملConcentrically Braced Frames: European vs. North American Seismic Design Provisions
A critical review of seismic design provisions for concentrically braced frames (CBFs) in both European and North American (i.e. US and Canadian) codes is presented in this paper. Indeed, even though those codes are based on capacity design philosophy, different requirements and different approaches are used to guarantee the hierarchy of resistances between dissipative and non-dissipative eleme...
متن کاملNumerical Simulation of Seismic Response Control of Frame Structure Using High-Temperature Shape Memory Alloy Wire
Both the Super-Elastic and Shape Memory Effect has been taken into account in this study by using SMA with high activation temperature. A Thermo-Mechanical SMA phenomenological constitutive model is used to simulate the SMA behaviour. The dynamic response data of a frame structure has been obtained from FE analysis by using the nonlinear FE software program MSC Marc. Then the frame is braced an...
متن کاملAnalytical Prediction of Seismic Response of Steel Frames with Superelastic Shape Memory Alloy
Superelastic Shape Memory Alloy (SMA) is accepted when it used as connection in steel structures. The seismic behaviour of steel frames with SMA is being assessed in this study. Three eightstorey steel frames with different SMA systems are suggested, the first one of which is braced with diagonal bracing system, the second one is braced with nee bracing system while the last one is which the SM...
