Papers in This Issue

摘要

The July 2013 issue of the Journal features 10 technical papers and one case study. Four papers deal with dynamic loads on bridges. In "Comparative Study on Buffeting Performance of Sutong Bridge Based on Design and Measured Spectrum," Wang et al. have analyzed the buffeting response of a cable-stayed Sutong bridge with a main span of 1,088 m using the wind spectra obtained from a long-term structural health monitoring system to compare the actual buffeting responses with those used during the design of the bridge. The autospectra of the longitudinal and vertical fluctuating wind components have been derived from the in situ strong wind data recorded by the monitoring system. The buffeting analysis is accomplished in a time domain with an aeroelastic effect included. Compared with the buffeting responses obtained from the measured spectrum, the girder responses from the design spectrum are larger in horizontal direction and smaller in other directions, whereas the tower responses are larger and thus relatively conservative. In "Mitigating the Effects of Wind on Suspension Bridge Catwalks" Kwon et al. have conducted wind tunnel tests and buffeting analyses for a catwalk structure of a suspension bridge under turbulent winds.
