The document outlines the objectives and methodology of research on analyzing complex shell structures. The objectives are to: 1) Analyze simply supported cylindrical, continuous, and multiple barrel shells using analytical and FEM approaches; 2) Evaluate the structural response to loads; and 3) Observe parameter variation for multiple barrel shells. The methodology is to: 1) Analyze shells analytically and compare to FEM results in SAP2000; 2) Increase complexity to continuous and multiple barrel shells analytically; 3) Perform FEM analysis in SAP2000; and 4) Draw conclusions and recommendations.
