# 附着铜箔式电阻应变传感器测量钢丝网水泥板平均应变实验研究An Experimental Study on Measuring Average Strain of Ferrocement Plate by Using Resistive Strain Sensor Pasted on Copper Foil

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.
