Concept improvement of behavior of X-Bracing systems by using Easy-Going Steel
The lateral deflections of buildings include bending and shear deflections. The bending deflection can be effectively controlled by combination of various types of coupled systems. But the shear deflection is controlled by increasing the shear stiffness of buildings. In this research, the new idea is introduced and application of Easy-Going steel ( EGS ) theory for improvement of behavior of X-bracing systems is discussed. The use of this theory for design of X-Braces can increase the lateral stiffness of buildings and decrease the lateral displacements. Moreover, the stability of this system increases and the P-Delta effects decline. So, the columns will be protected against reaching nonlinear state and most of the energy dissipates by braces. The area under hysteresis curves augments and the energy dissipation capacity of this system enhances considerably. Also in this research comparison between general designed braced frames using structural steel and braced frames with Easy-Going steel concept is performed using harmonic Analysis to verify benefits of using this theory to decrease earthquake response of the structure during resonance.
