摘要
预应力混凝土矮T梁是一种新型的桥梁结构,而将其用于大角度斜梁当中,使得问题的研究更加复杂化。为了探讨预应力混凝土矮T梁的力学性能,分析斜梁桥在荷载作用下的受力特点,先后采用空间有限元分析方法及广义弹性支承连续梁法进行了理论研究和设计分析。计算结果表明:采用广义弹性支承连续梁法对矮肋斜T梁桥进行受力性能分析能取得较好的计算精度,并可用于工程设计当中。
Prestressed concrete T-shaped skew bridge with low web is a new type bridge structure,but it seems to be more complicated in the case of skew bridge with large angles.To discuss the mechanics performance of skew T-shaped beam with low web and analyze the mechanics property of skew bridge,spacious FEA methods are adopted in this paper.Calculation results show that general elastics supported continuous beams methods can obtain better precision and can be applied in engineering design.
