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.
