钢筋混凝土简支梁固有频率的数值计算

Numerical computation of natural frequencies of reinforced concrete simply supported beams

通过振型函数导出了求解梁横向振动固有频率的微分方程,在组合梁理论的基础上推导了完整钢筋混凝土梁固有频率的计算公式,对实际简支梁进行了动力试验,验证了固有频率理论计算公式的准确性。

In this paper,vibration mode function derived by solving the natural frequency of transverse vibration of beam differential equations,based on composite beam theory,the derivation of a complete reinforced concrete beam natural frequency formula.Simply supported beam of actual dynamic test carried out to verify the natural frequency theory,the accuracy of the formula.
