Abstract
In the braced excavations, careful consideration must be given to the risks of progressive collapse of the entire support system due to failure of a single member. The existing connection methods of the excavation support system results in many problems during construction. To overcome these, simple joint method is proposed in this study. The full scale test and the numerical analysis using finite element method were performed to verify the safety of them. As results, simple joint method was good effective to increase strength. And it was good effective to decrease in numbers of bolt. Also, new method is cheaper than existing connection methods and a good construction as well.
