摘要
木结构楼盖是木结构居住建筑中最为常见的结构系统,又是唯一一个与居住者不时有身体接触的系统。在居住环境中,居住者自身或别人的活动经常会造成楼盖振动,给居住者带来不适。如何减少令人烦恼的楼盖振动,是一个非常复杂的问题。以实木锯材搁栅楼盖为研究对象,选取1 kN静态挠度和基本自振频率为振动性能评价参数,结合评价者对试验木结构楼盖的主观感受,研究了我国实木搁栅木结构楼盖振动控制设计方法。结果表明,当实木锯材搁栅楼盖基本自振频率与其中心处1 kN静态挠度的0.44次方之比大于20时,可评定该楼盖为可接受楼盖。
Timber floors are by far the most common structural systems used in wood-framed residential buildings,and are the only systems with which human occupants are in constant physical contact.In dwellings,the floor vibration due to walking often brings discomfort to the occupants.Designing a house that controls the agonizing vibration of floors is a difficult problem.The vibration performance of five solid wood lumber joist floors was studied as were subjective opinions of evaluators.The 1KN static deflection an...
