摘要:
提出将电阻应变传感器黏贴在薄而延性很好的铜箔上,用来测量钢丝网水泥板弯曲加载下的平均应变的方法。这种方法可以得到钢丝网水泥板受弯曲作用下一个完整的载荷–应变曲线。通过转换,通过弯曲应变数据结果计算出裂缝宽度,这包括初始裂缝宽度、最终裂缝宽度和载荷–裂缝宽度曲线。荷载-位移曲线和载荷–应变曲线表明,钢丝网水泥板具有良好的弯曲强度和抗裂性能。

Abstract: A method of using resistance strain sensor pasted on the thin copper with good ductility to measure the average strain of the ferrocement plate under the bending load is proposed. This method can get a full load and strain curve ferrocement plate under flexural load. By transformation, the crack width is calculated by the bending strain data including the initial crack width, final crack width and load curve of crack width. The load-displacement curve and the load-strain curve show that the ferrocement plate has good bending strength and crack resistance.
