增加中间支点的数量，纵向振动的振幅减小。
The amplitude of longitudinal vibration is decreased when the number of intermediate supports is increased.
建议在采用此方法加固多跨简支T梁的同时应对中间支点梁的抗剪能力进行加固。
Thus, when reinforcing the multi-span simply-supported T-beam by this method, enhancing the shear resistance of beam at intermediate support must be conducted yet.
可通过减小偏心距、降低主共振的阶数、加大传动轴及中间支点处的阻尼，使传动轴主共振不分岔。
The bifurcation of main resonance can be removed by reducing the eccentricity and the order of main resonance and increasing damping of the driving shaft and intermediate supports.
