Abstract
Compared to the tower of common twospan suspension bridges, the middle towers of multispan suspension bridges have several different characteristics, such as the constraints, service conditions and loads, etc, which affect the safety and applicability of the bridges. In this paper, a small-scale model was designed for the middle tower of Taizhou Bridge, based on its actual working conditions. By the finite element method, the similarities between the experiment and the prototype were investigated from three aspects, including the internal forces, displacements and strains. It is demonstrated from the investigation that, with the geometric size and material modulus as the essential parameters, the designed model herein can satisfy the requirements of mechanical properties of experiment.
