摘要

The November 2010 issue of the ASCE Journal of Bridge Engineering features 14 technical papers, one technical note, and one closure. The issue begins with four papers on the dynamic behavior of bridges during seismic and wind loads. The paper titled "Performance Test of Energy Dissipation Bearing and Its Application in Seismic Control of a Long-Span Bridge" by Guan et al. describes a performance test of an energy-dissipation bearing (EDB) consisting of a conventional steel bridge bearing in connection with well-designed mild steel dampers. Experimental results show the bearings to be very stable and have high dissipation characteristics. Through their application on the long-span bridge over the Nanjing Jia River, the authors show that EDBs achieve a very high effectiveness in seismic control in both the longitudinal and transverse directions. Compared with other damping devices, these bearings provide a simple but valid seismic control solution with low maintenance requirements, especially in the transverse direction.
