摘要
应用最小余能原理的理论和方法 ,对Timoshenko梁进行动力分析 .分别计算了对称截面及非对称截面多跨连续梁 ,当相邻跨按对称振型振动时的固有频率 ,讨论了不同边界条件对固有频率的影响 .
In this paper,the minimum excess principle are used in dynamic analysis of Timoshenko beam.The natural frequencies of symmetrical section and non-symmetrical section continuous-beam are calculated in detail,and results of continuous-beam with different constraint conditions are given.
