本文介绍预应力双层索系的大模型试验,在静力方面,考察了体系在各种不同形式荷载作用下的内力和变位:在动力方面测定了体系的各阶频率以及相应的阻尼。试验结果为预应力双层索系这种结构形式的工作性能提供了较为完整的概念,并很好地验证了理论。
This paper introduces the large-scale model test of prestressed double-layer cable system. In the aspect of static force, the internal forces and displacements of the system under various forms of loads are examined. The frequency and corresponding damping of the system are determined in terms of dynamics. The test results provide a more complete concept for the working performance of the prestressed double-layer cable system structure and well verify the theory.
