| Abstract: | This article analyses in space coordinates the calulation of the indexes about crane's horizontal rigidity. It takcs fully account of the generalized restraint forces action in portal bridge box space structurc and rigitidy adaaption action. It ensures the harmony and continuity of deformation in structure. It revises the tradilional calculation mcthod, and puts forward the new factual calculation formulae, therefore, it improves the reality of commeit for gantry erane's horizontal rigitidy. |
