本文研究了一些因素对拱式结构固有频率的影响,这些因素是外荷载,剪切变形,拱轴形状,拱上建筑以及水平惯性力等。本文用图解分析法和矩阵理论来求解。计算结果表明本法精度甚高。研究成果可供工程设计之用 This paper studies the influence of some factors on the natural frequencies of arched structures, such as external load, shear deformation, arch shaft shape, arched building, and horizontal inertial force. This paper uses graph analysis and matrix theory to solve. The calculation results show that the accuracy of this method is very high. Research results can be used for engineering design
