Design of Buckling Restrained Damper for Retrofit of Steel Truss Bridge
The seismic design codes have been revised whenever severe damage was observed in the aftermath of a seismic event. The seismic resistance of quite a few existing bridges may not be satisfactory for the current seismic design codes. Retrofit is needed for those bridges. To this end, the application of the device of the buckling restrained bracing (BRB) to a steel truss bridge as a damper (BRD) is explored. A parametric study on the seismic performance of the truss bridge with the BRD is conducted by changing the length and the cross-sectional area of the yielding core of the BRD. The numerical results by the nonlinear dynamic analysis show that the BRD surely improves the seismic performance of the bridge. It is found that a shorter length tends to work better and a larger cross-sectional area enhances the safety. The study concludes that an appropriate design of the BRD would help steel truss bridge stay intact even under a rather large seismic loading.
