Abstract: In this paper,two full-scale typical joint specimens strengthened by plate rings with irregularly arranged double levels beams are conducted to learn the mechanical behavior and collapse mechanism.The tests imply that the stresses in the beam flanges can be effectively transferred by the strengthening plate to the steel tube,and the in-between co-activity will be somewhat affected when stressed simultaneously.Good working performances of this type of joint can be guaranteed with rational designs...
