摘要

针对固体材料弹性阶段内阻尼,采用粘弹性材料本构关系,通过振型分解法推导建立了简谐荷载激励下材料粘滞系数的测试理论,包括存在钢筋的情况;利用三点弯曲梁式材料阻尼测试装置,对6种不同配合比复合纤维增强阻尼混凝土的粘滞系数进行了试验测试,表明测试理论的可行性,并对试验结果进行了简要探讨.
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.
