木楼盖人致振动性能浅谈

A Tentative Analysis on Human-induced Vibration Performances of Timber Floors

木楼盖具有质量轻的特点,在使用过程中容易受人们日常活动的影响而产生令人不适的竖向振动。对于建造中大跨度楼板,振动舒适度是设计师和工程师最为关注的问题。楼板振动性能是振动舒适度的具体表达指标。系统归纳整理了影响木楼盖动态振动性能的主要因素,介绍了当前木楼盖振动舒适度的设计标准和最新改进方法,并对中大跨度木楼盖振动性能研究提出建议。

Due to its light-weight,the timber floors often produce uncomfortable vibrations induced by human common activities of run,jump and so on.With respects to the construction of middle-and large-span timber floors,their vibration serviceability is the most concerned issue for designers and engineers.Vibration performances are specific expression indicator of the vibration serviceability of timber floors.Factors affecting the dynamic vibration performances of timber floors and their interrelation ships were systematically summarized.The design criterions and newly controlling methods on vibration performances of timber floors were clearly introduced.The development and suggestion of vibration performance researches on middle-and large-span timber floors were objectively presented.
