Ld.Beijing 102200 China) Abstract:Because of its own superiority the cuplok steel tubular supporting frame has been more and more used in long-span building construction and bridge construction.Unfortunately the supporting frame accidents occur frequently.The major cause of such accidents is the imperfection of the bearing capacity theory on the supporting frame.In order to study the effects of bay length and outside bracing on the bearing capacity and according to the engineering application three elaborately-designed full-scale tests were carrized out moreover the details of bearing capacity failure modes load-displacement curves stress distribution and horizontal displacement data were gained which will b...
