| Abstract: | The paper mainly studied the linear inner-damping of solid material.Based on the constitutive relation of viscoelastic material,the testing theory for viscous coefficient was deduced by using mode-shape decomposition method,when the beam is under Sinusoidal load.Also this theory can be used for testing steel reinforced beam's viscous coefficient.Secondly,the viscous coefficient for fiber reinforced concretes of six different ratios was measured,it was proved that this testing theory was feasible.Finally,the testing result was discussed briefly. |
