钢筋混凝土雨蓬和悬臂楼梯是砖石混合结构常用的构件,关于此类悬挑构件倾覆破坏的形式和机理,有关教材和规范未作规定。为了配合彻体设计规范的修订工作,我们对雨蓬和悬臂楼梯进行了一些试验研究工作,本文通过试验分析,对雨蓬等构件的设计方法提出建议。文尾附有详细数据及图形。 Reinforced concrete canopies and cantilevered stairs are commonly used components of masonry mixed structures. There are no regulations concerning the form and mechanism of overturning failure of these cantilevered structures. In order to comply with the revision work of the thorough design specification, we conducted some experimental research work on the canopy and the cantilevered staircase. Through experimental analysis, this paper proposes suggestions on the design methods of canopies and other components. The text is accompanied by detailed data and graphics.
