Abstract:
In order to reduce the seismic demand and enhancement the ductility capacity, vertical link beams as a ductile element are used in eccentrically braced frames. During the earthquake, vertical link beams dissipate the energy by forming nonlinear deformations in their plastic region while the other members remain in the elastic range. In EGS, the percentages of carbon and other alloys are very low. EGS has high ductility. The most ductile kind of easy-going steel has a nominal yielding stress between 90-110 MPa and its Young’s modulus is equal to that of normal steel. In Fig. 1, the stress-strain curve of this steel is compared to that of normal steel. If the vertical link beam is made of EGS, which yields at smaller stress compared to the normal steel, its performance and energy absorption will improve as shown in Fig. 2.
