摘要
当预制预应力混凝土双T板端部为企口形式时,不仅可以降低支承梁高、增加板的稳定性,还可以灵活地与牛腿、倒T型和L型支承梁搭配使用,有很好的应用前景。为了更进一步了解双T板企口的力学性能,本文通过有限元软件ABAQUS对带企口双T板中企口区域进行三维非线性分析,来研究各种参数对企口力学性能的影响,最后对有限元分析的结果进行总结,得出对双T板企口力学性能有重要影响的因素,并提出了双T板企口的相关设计建议。
When the end of double-tee is dapped, it can reduce the height of supporting beams with a greater lateral stability;besides, it can be used with brackets, inverted T beams and L-shaped beams flexibly with great application prospect. Base on ABAQUS, non-linear finite element analysis was used to model the behavior of the dapped end of double-tee to study the effects of various parameters believed to affect the mechanical behavior of dapped-end. Finally, the results of the finite element analysis are summarized, and the parameters which have important influence on the mechanical properties of the double-tee dapped end are determined, and the design recommendations of the double-tee dapped end are proposed.
