Abstract
Shells are important components of many industrial complexes. Performance of shells due to the extreme loading conditions shows that buckling is the major failure mode in such components. Shells have several applications in engineering structures and most particularly in civil engineering, and mechanical engineering, architecture, aerospace and marine industries.
Although Shells are important components of many industrial complexes, and they are becoming more prominent these days, many researches are required to buckling in shells. The best way to cover this point is the parametric study on stability of shell roof structures under different load types. There are different methods used in these decades the proposed method is not covered yet. During the past decades, several researches have been conducted on the stability of shell roof structures under different load types.
The main purpose of this study is to propose a methodology that the stability of shell roof Structures under different load types. The data used in this research was collected according to theoretical values, model geometry, different loads, and buckling of shell. The models use the finite element method to give recommendations or guidelines to study the stability of shell roof structures under different load types.
A compare between results of analytical model by ANSYS and collector models are used to validate the proposed models. The contribution of this study is to present a reveal that the different load types on shell roof structures can play a noticeable role in creating stress concentration and effect destructively the stability of structures.
