竹胶合板模板蠕变特性研究

Study on Creep Performance of Plybamboo Form

对竹胶合板模板在干、湿两种状态下纵横方向弯曲蠕变特性的研究结果表明,竹胶合板模板的横向弯曲初始蠕变量要大于纵向弯曲初始蠕变量;湿状态下竹胶合板模板弯曲的初始蠕变量要显著大于干状态;湿状态下竹胶合板模板在纵向弯曲稳定蠕变阶段的蠕变速率是干状态的2倍;弯曲蠕变断裂的试件在稳定蠕变阶段有显著大的蠕变速率,最终导致材料断裂。

Creep performance of plybamboo form on the longitudinal and cross under dry and wet condition condition condition was studied. The result shows that cross creep of plybamboo form was bigger than the longitudinal, and wet condition creep was bigger than dry. Wet creep rate is twice as much as that of dry in the longitudinal steady creep stage of plybamboo, and the plybamboo with bigger creep rate in steady creep stage would be broken.
