Abstract

Three groups of displacement decay curves, corresponding to rebars, mortar cantilever beams and concrete cantilever beams under different vertex displacements were measured; and the variation law of damping ratio and deformation (including plastic deformation ) of high damping Concrete members on plastic stage were obtained. In addition, the influences of polymer-cement ratio, latex blend and different fiber on compressive strength and damping ratio of Concrete were analyzed. Based on these results, some new calculation formula for damping ratio of concrete members was proposed. The comparison of the relevant researches at home and abroad was given to demonstrate the validity of the proposed method in this paper.

Key words
