The main task of the current study is to present the formulation of a free vibration analysis method considering all deformations of step tubular structures of tall buildings supported on elastic foundation soil, as long as the many tall building systems might be simplified as tubular structures[6,7,8] of continuous distributions of material property, and for the purpose of the application of ordinary differential equations (ODE) solver to the dynamic analysis of tall buildings structures.

Several approaches have been adapted to improve the stiffness and stability of
flatbed air bearing, such as: add compensator or stabilizer such as damping cavity on air bearing [1, 2];
Change the surface profile of air bearing with grooved bearing [3], arc surface [4], conical shape [5,
6], or more complicated tri-conical gap-shaped holes [7]; and Change the bearing surface structure or
use membrane type bearing [5, 8], or adapt porous material bearing [9, 10].
