Abstract:
A design method for the static and dynamic test model of Dongjiang Bridge(double-deck and three main trusses steel bridge with rigid cable)was introduced. It presented an advance method based on stiffness similarity to ascertain equal similar relationships, which more effectively solved the design problem of model with difference of elastic modulus ratio in different parts between model and practicality, and through increasing additional mass, coherent similarity ratio of frequency between model and practicality was got. At last,authors introduced a calculation method of self-weight and moving load of model in brief. The method solves the trouble brought by many points of load and uneven mass.
