本文针对钢筋混凝土小比例尺模型,提出了考虑不同材料(混凝土和配筋)间相似性协调问题的一种新型设计方法,即通过调整配筋率、配箍率或者截面有效高度(h0)、箍筋间距等,对微粒混凝土和配筋的相似性协调进行考虑,并且通过构件试验、振动台实验和数值模拟来研究其可行性、有效性,而且通过相似偏差分析可知:相似性协调模型能很好地模拟原型结构弹塑性性态。
In this paper,a new method of considering similitude harmony problem between various materials(reinforcement and concrete) for small-scaled RC model design is put forward,that the similitude harmony between concrete and reinforcement used in model is considesed by adjusting reinforcement and stirrup,or the effective section height(h0) and hoop space etc.Simple element testing on a shaking table and numerical simulation are carried out to verify this model design method,moreover,it is evidenced by deviation ...
