热环境下钢筋混凝土矩形板的振动

Vibration of Reinforced Concrete Rectangular Plate under the Thermal Environment

对处于热环境作用下四边简支的钢筋混凝土矩形板,采用基尔霍夫(Kirchheff)薄板理论,建立了控制方程,采用级数法导出板的固有频率,并讨论了几何尺寸、物理参数和温度变化对板的固有频率的影响,为在工程设计时进行振动计算提供理论依据。

According to the Kirchheff thin plate theory, a control equation of reinforced concrete rectan- gular plate in the thermal environment was established, and the natural frequency of the plate was export- ed using the series method. The impact of geometry, physical parameters and temperature change on the natural frequency of plate was discussed, providing a theoretical basis for the calculation of the vibration for engineering design.
