摘  要：
在简支条件下,应用振动无损检测法测定了胶合木梁的固有频率并算得其弹性模量值,同时采用振动分析有限元法计算胶合木梁频率值和用静载试验测定其弹性模量。通过对振动测试、振动分析及静载试验共3种方法得到的结果进行比较,证明了振动法测试胶合木梁弹性模量的可行性和准确性。

摘  要：
Under the condition of simple-supported, by adopting vibration NDT method, the natural frequency of glued laminated beams were measured and the elastic module values of the beams were also computed. Meanwhile, by using vibration analysis finite element method, the glulam beams frequency values were calculated and the glulam beams elastic modulus were determined through static tests. The comparisons among the results of vibration testing, vibration analysis and static load tests were conducted, the comparative results proved the feasibility and accuracy detecting glued laminated beams' elastic modulus with vibration methods.
