    • An strain measuring apparatus for analyzing the stability of a steel structure and a method thereof employs a controller for receiving a variation difference amount from the strain gauge input unit measured using a strain gauge between a strain degree obtained by applying a weight to a steel structure and a strain degree obtained by applying a weight to a steel structure having a hole formed at a predetermined portion and measuring a strain existing in the steel structure based on the variation amount using particular equations. A control command input unit inputs an initialization command for initialing the existing strain measuring apparatus, a radius of the hole formed in the steel structure, a distance between the center of the hole and the center of the strain gauge attached to the steel structurc and an external operating signal including a proceeding command which represents a testing procedure into the controller. A display unit displays the operating procedure of the controller and the existing strain measured, whereby it is possible to measure an existing strain of the steel member at a construction site in which a steel member is provided.
    • 用于分析钢结构的稳定性的应变测量装置及其方法采用控制器,用于接收与使用应变仪测量的应变仪输入单元的变化差值,所述应变仪在通过将重量施加到钢结构获得的应变程度和 通过在具有在预定部分形成的孔的钢结构上施加重量并且使用特定方程式基于变化量来测量存在于钢结构中的应变而获得的应变度。 控制命令输入单元输入用于初始化现有应变测量装置的初始化命令,钢结构中形成的孔的半径,孔的中心与附接到钢结构体之间的应变片的中心之间的距离,以及 外部操作信号包括表示到控制器的测试程序的进行命令。 显示单元显示控制器的操作过程和所测量的现有应变,由此可以在设置钢构件的施工现场测量钢构件的现有应变。
