通过抗裂度对预制板的开裂性能进行评价,并用Ansys有限元分析软件对竹筋多孔混凝土预制板进行应力和挠度有限元分析,对预制竹筋多孔混凝土板的开裂弯矩和受力变形发展情况做了探讨,结果表明在多孔混凝土中加入竹筋,可以有效的改善多孔混凝土的脆性,加入竹筋的预制板其开裂弯矩相对值可以达到不加竹筋的2倍以上,可以明显改善预制板的抗裂性能。预制板的受力和位移是中心点处最大,结构的破坏一般都是在受力最大处或者是变形最大处。
通過抗裂度對預製闆的開裂性能進行評價,併用Ansys有限元分析軟件對竹觔多孔混凝土預製闆進行應力和撓度有限元分析,對預製竹觔多孔混凝土闆的開裂彎矩和受力變形髮展情況做瞭探討,結果錶明在多孔混凝土中加入竹觔,可以有效的改善多孔混凝土的脆性,加入竹觔的預製闆其開裂彎矩相對值可以達到不加竹觔的2倍以上,可以明顯改善預製闆的抗裂性能。預製闆的受力和位移是中心點處最大,結構的破壞一般都是在受力最大處或者是變形最大處。

Bamboo reinforced porous concrete prefabricated plate is customarily damaged by the slope deformation force .The cracking strength of prefabricated plate through crack resistance have been evaluated in this paper , and finite element analysis has been made on bamboo reinforced porous concrete prefabricated plate by using Ansys finite element analysis software .Through two methods , the cracking moment and deformation development of the slab have been discussed .The results show that the brittleness of porous concrete can be improved effectively by adding bamboo reinforcement and the cracking moment of relative value of the bamboo reinforced precast slab can be achieved more than 2 times of without bamboo reinforcement .The stress and the displacement of precast slab is the largest at the center and the destruction of the structures are generally in the maximum stress or deformation of the maximum .
