If the bracket triangle are commonly used, you may issues such as withdrawal caused by mounting unstable bracket phenomena and bending wire, the eccentricity of the loading plate than steel when you change the angle of the hole during construction will occur. SM brackets adjustment of the angle of 25~40 degrees is possible adjustment of the angle of the ground anchor bracket arched surface, the change in distance between the fixing position of the line and band pieces, due to changes in the installation angle, designers from steel Unlike with the intention, it is possible if the corresponding method can be constructed. Also, For construction of temporary structure used anchor, it will be reinforced with stiffener to prevent excessive deformation of the wale. In general, the welded steel stiffener is used. Construction of welded steel stiffener is costly and time-consuming and cause the problem that wale does not reuse. In order to solve these problems, various kinds of non-weled stiffeners are being developed.

For construction of temporary structure used anchor, it will be reinforced with stiffener to prevent excessive deformation of the wale. In general, the welded steel stiffener is used. Construction of welded steel stiffener is costly and time-consuming and cause the problem that wale does not reuse. In order to solve these problems, various kinds of non-weled stiffeners are being developed. In this paper, non-welded and conventional welded stiffener for maximum strength, fracture pattern and the residual stregth due to cyclic loading is to evaluate.
