钢筋混凝土楼梯变形试验研究及设计建议

Experimental Study and Design Advices on Reinforced Concrete Stairs Deformation

在分析有关文献资料的基础上,考虑各种不同因素的影响,对试件进行了优化设计,初步探讨了钢筋混凝土楼梯梯段的破坏和变形特征,提出考虑踏步作用的楼梯梯段挠度计算方法。对比试验结果表明,本文建议的设计方法不仅能更好地反映楼梯踏步的作用,计算结果更符合梯段的实测变形,而且方法简便,可为实际工程设计提供参考。

Based on the analysis of literature materials and various influence factors considered, the experimental specimens were designed optimally. The destructive and deformable characteristics of reinforced concrete stairs were preliminarily explored. As a result, a simplified deflection calculating method that takes the action of stairs treads into account is derived. In comparison to the experimental results, it is found that the present method, which has good agreement with the test results, not only can well reflect the tread action, but also provide a handy and feasible method, for stairs design.
