Dot corrosion and delamination models were employed during the simulation . finally , the mechanical properties of a t - beam of an actual bridge have been analyzed 最后本文对北京市一座在役道桥的t型梁,进行了有限元模拟,对其受力状况进行了评估。
At last the results obtained are compared with those of t - beams , which shows : 1 ) the base frequency of t - beam and box girder bridge is different not only in the value but also in vibration direction 通过与此无关t型梁自振特性的结果进行比较,得出了一些重要结论:从t型梁到整体箱梁,梁的基频发生了改变。
2 ) the value of base frequency , which is the first order vertical - bending vibration , is bigger in box girder bridges than those of t - beams . it shows that the vibration performance of box girder bridge is better than t - beams . 3 ) when considering the shear deformation of beam , the vibration frequency calculated by is bigger than those not considering the shear deformation T型梁的基频为横向振动,而整体箱梁的基频为竖向弯曲振动;整体箱梁的一阶竖弯振动的频率比t型梁得到了提高;整体箱梁的动力性能优于t型梁;考虑剪切变形后,梁的自振频率降低,对于整体箱梁其降低值接近于5 ,在分析时不应忽略。
百科解释
A T-beam, used in construction, is a load-bearing structure of reinforced concrete, wood or metal, with a t-shaped cross section. The top of the t-shaped cross section serves as a flange or compression member in resisting compressive stresses.
