System Simulation Theory and Its Application to Concrete Cable-Stayed Bridge Construction

With the development of cable-stayed bridge, the simulation of construction process is becoming more and more important. The object-oriented visual modeling method for complex engineering system is carried out with the application of the system simulation technology and three-dimensional animation technology to the simulation study of bridge construction processes, which constitute of the visual simulation methodology. Based on the construction speciality of a practical cable-stayed bridge, the modeling method of system simulation is elaborated. Combined with the cycle operation network technique, bridge simulation analysis software (BSAS) for construction of bridges is programmed with VC + + . The successful application of the software to the construction of the practical cable-stayed bridge shows the feasibility and effectiveness of the method.
