We investigate the influence of longitudinal structuring on the fast kink modes of the coronal loops oscillations. Using a simple longitudinal exponential density structure, an analytical dispersion relation is derived. The properties of oscillatory periods and mode profiles and their deviations for such stratified structure are compared with those of the homogeneous tubes. Also, the effects of negative scale heights and total mass column on oscillation and mode profiles of the loops are investigated. Here we confirmed that the shift of the antinodes and mode profiles and the ratio of the frequencies are potentially good tools to estimate the density scale heights of the solar atmosphere.
