Research on the influence of mechanical parameters on concrete self anchored suspension bridge structure
The paper is based on a concrete self anchored suspension bridge,selecting design parameters such as the weight of the main cable,the weight of the main beam,and the shrinkage and creep of the concrete material.The midas Civil large-scale finite element analysis software is used to explore the influence of the above design parameters on the shape of the main cable and the internal force of the cable of the bridge.The results show that in the design process and construction monitoring calculation,accurate statistics should be made on the permanent loads of the main cable and stiffening beam to find a reasonable bridge completion state,and subsequent work should be carried out on this basis.The concrete main beam is greatly affected by shrinkage and creep,which changes the shape of the main cable to varying degrees.The concrete age should be appropriately increased to reduce the adverse effects of shrinkage and creep on the bridge alignment.
