The vertical loaded free frequencies for the different spansimplysupported beam Bridges are investigated with the vehicle bridge system model.
采用车-桥系统相互作用的计算模型，对不同跨度简支梁桥的竖向有载自振频率进行了深入研究。

Traditional methods treat each span segment as a simply-supported beam or clamped-clamped beam in practice.
传统方法是将悬跨管道简化为两端简支或者两端固支梁来处理。

Thus, when reinforcing the multi-spansimply-supported T-beam by this method, enhancing the shear resistance of beam at intermediate support must be conducted yet.
