| 摘要： | Road authorities in Switzerland are facing growing numbers of passage requests for special transports, i.e., for oversized, overweight vehicles along specific routes. These requests have to be processed quickly and accurately. In particular the effect of overweight vehicles on bridges must be accurately assessed. A software program, TRUCK, assists authorities in this task. It is based on a comparison of internal forces (bending moments and shear forces) under design-code loads and loads induced by special transport. For this purpose the bridge structure is numerically simplified into a sequence of simply supported beams. By virtue of this simplification the application TRUCK is both fast and easy to use. Development of the TRUCK program was based on object-oriented methodology. The system model resulting from requirement analysis is shown and shortly discussed. During development, special attention was paid to the modeling of code loads. TRUCK's software architecture is based on the three-layer model. Finally, a TRUCK representation of an actual bridge subjected to special-transport loads is described. |
