【摘要】 本文研究现浇混凝土圆柱形填充体复合板的正交各向异性,通过有限元法对不同直径和不间距的复合板进行了分析,计算归纳出复合板的两个方向的刚度比,给出了两个方向的宏观弹性模、剪切模量和泊松比的计算公式,该公式误差小,计算方便,为现浇凝土圆柱形填充体复合板的计算和设计提供了理论依据。更多还原

【Abstract】 The orthotropy of cast-in-situ concrete composite plate with cylindrical infill is studied in the paper.The rigidities in two directions of the composite plate with various diameters and various distances are analyzed by FEM.The formulae to calculate the elastic modulus,shear modulus and poison ratio in two directions are given.They are easy to use and have small inaccuracy.The paper gives the theory basis to calculate and design the cast-in-place concrete composite plate with cylindrical infill.更多还原
