摘要
本文根据对工业厂房使用情况的调查资料,对以往厂房中习用的水平制动桁架及其损坏特征,进行了定性和定量分析。发现以往的水平制动桁架形式,对于在重复行动荷载作用下抵抗疲劳的能力较差,从而提出了改进后的桁架形式及其设计方法。
The horizontal checking truss, habitually used in former factory building, and its damaged charac-teristics, are analysed qualitatively and quantitatively according to the investigated data of industry facto-ry building. It is revealed that the form of the former horizontal checking truss has a comparativelyweak fatigue resistance under repeatly moveable load. Thus, the improved form of truss and its designmethod are put forward.
