| 摘要： | This report documents results from field and computational studies on trapezoidal box girders. Field studies were conducted on a three-span continuous curved box girder bridge. More than eighty strain gages were applied to the girder cross-section and the top flange lateral truss prior to girder erection. Stresses in the girder and bracing members were monitored during erection, construction, and subsequent live loading. The construction of the box girder bridge was simulated with a three-dimensional FEA model of the quasi-closed steel section. Results from the field studies were used to study the girder behavior during construction and also the interaction of adjacent girders during live loading. |
