| Abstract: | Prestressed space grid developed in recent years has good performances,but its bottom chord joint is hard to dispose.A new type of joint\_welding hollow sphere joint with holes(WHSJH)is put forward,its load carrying capacity and influencing factors are researched by means of the finite element method and full scale model experiments.Some conclusions beneficial to design are drawn satisfactorily. |
