钢筋混凝土空心板的动力分析

Dynamic Analysis of Forced Vibration of Circular Voided Reinforced Concerete Slabs

文中首先借助Dirac函数,建立钢筋混凝土空心板在任意激励下的振动方程,然后应用正交各向异性板壳理论,取双重级数作为试函数,通过Laplace变换及逆变换给出钢筋混凝土空心板受迫振动的动力响应.对地震力作用下的解也可用类似方法求得.

Based on the Dirac δ function, this paper establishes the forced vibration equation of circular voided reinforced concerete slab and with the application of elastic theory of orthotropic plate and a double trigonometric series, the analytical solution of forced vibration would easily be calculated, through appropriate mathematical transformations. When earthquake force is applied on the R. C. Slab, the solution would be given similarly.
