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.
