Abstract EN
In this paper, the effect of different types of stiffeners on the cylindrical shell structure is presented.
The stiffened shell models are examined under the action of static and dynamic excitations.
Finite element models for the different stiffened cylindrical steel shell have been created by considering the helix angles and height of stiffeners, and a cantilever supported models are used.
Additionally, the models are assumed to have a constant mass which is (4 kg) .
All structure models have examined under action of static, harmonic and transient loads.
Also the dynamic properties (natural frequencies) are computed for each FEMs.
A concentrated load of the magnitude of (100 N) in three directions (x, y and z) is used in these structural analyses (static, harmonic and transient).
This force is applying to the upper edge which is opposite the clamping edge .
From these analyses, the best helix angle occurs at stiffener angle (90P o P), and the best height of stiffener that the modal analysis gives is (2 cm) and that gives by other analysis is (6.25 cm) .
Finally, a comparison between experimental work of [M.

and A.
A.
