A Static Analysis of the Concrete Shell Roof Structure

The paper presents a static analysis of the cylindrical concrete shell roof structure The paper provides the basic characteristics of shell structures. The numerical simulations using the Finite Element Method (FEM) in the software ADINA were used for the solution of the cylindrical concrete shell roof subjected to gravity loading with different values of length. The article presents the vertical displacements and the maximal values of FE effective stresses of the cylindrical shell roof construction and their dependence on the considered length and their trends.

I. Introduction

The shell structure is lightweight thin-walled, usually only a few centimeters thick, and most often a reinforced concrete structure. It has a curved, bent, or otherwise modified shape, thanks to which the structure gains rigidity. In principle, it imitates eggshells, rolled or accordion-folded paper. These are always very thin materials, the stiffness of which depends on their shape, and they guarantee maximum strength and durability with minimal mass, [1],–[5].
