CALCULATION OF MONOLITHIC STABILITY OF FRAM ED TUBE STRUCTURE IN SUPERHIGH BUILDINHS

In this paper,the energy variational method is extended to the calculation of the monolithic stability of framed tube structure.The mathem-aticalm odel of an eguivalent continuum is outlind and the displacement fun-ctions given not only satisty the boundary conditions but also conform wi-th the effect of shear lag on the tube. All computation can be easily performed by using mini-computer with ess processing time,
