In the nuclear power plant, safety-related structures have been used above No. 11 rebar. It needs to mechanical connection device to join RC to SC walls because ACI 349 presents that lap splices shall not be used for bars larger than No.11 bar. The performance tests were performed to confirm structural integrity on connection of RC to SC using a mechanical connection device. But performing the tests in accordance with various connection cases has limitations, such as time or cost. Therefore, computational analysis methodology is developed in order to verify structural integrity for various connection cases.
