本文为一斜拉桥模型动力和静力试验的总结,测试了模型沿三个轴向的14个自振频率及相应振型,分析了斜拉桥的振动特点和抗震能力,完成了在横向和竖向各种不同荷载下挠度和应变的测量,表明结构有足够的水平向和竖向刚度。
This paper summarizes the dynamic and static tests of a cable-stayed bridge model. The 14 natural frequencies along the three axial directions and corresponding vibration modes are tested. The vibration characteristics and seismic capacity of the cable-stayed bridge are analyzed. And the vertical deflection under various loads and strain measurements show that the structure has sufficient horizontal and vertical stiffness.
