现浇混凝土空心板面层厚度对受力性能影响的有限元分析

Based on finite-element method analyses the the deflection ,section normal stresses and reaction of cast-in-situ reinforced hollow slab influenced by the thickness of concrete up and under the tubes changing when the diameter and interval of hollow tubes and the thickness of hollow slab are not changed.With the the thickness of concrete up the tubes becoming biger,the deflection,section normal stresses and the dissimilarity of parallel slab and perpendicular slab is becoming smaller.
