For example, the engineer may use beam elements for the analysis of shear walls rather than using planar elements (plate elements or plane stress elements) based on his/her judgment. For practical reasons, the engineer may simplify or adjust the numerical analysis model as long as it does not deviate from the purpose of analysis. Real structures generally comprise complex shapes and various material properties. However, it is not always easy and may be sometimes uneconomical to accurately reflect every stiffness property and material property of the structure in the numerical analysis model.

This can be accomplished by comprehensive understanding of the elementsвЂ™ stiffness properties that affect the behaviors of the real structure. Finite elements, accordingly, should be carefully selected so that they represent the real structure as closely as possible. The structural properties, however, implicate a significant effect on the analysis results, as the results highly depend on modeling methods and the types of elements used to construct the numerical analysis model of the structure. External conditions such as loading conditions may be determined by applicable building codes or obtained by statistical approaches. For a successful structural analysis, it should be premised that the structural properties and surrounding environmental conditions for the structure are defined correctly. It allows the practicing structural engineers to investigate the behaviors of the structure likely subjected to anticipated eventual circumstances. A structural analysis refers to mathematical simulations of a numerical analysis model of a structure. Boundary conditions represent the status of connections between the structure and neighboring structures such as foundations. Finite elements are used in data entry, representing members of the structure for numerical analysis, and nodes define the locations of such members. Numerical Analysis Model The analysis model of a structure includes nodes (joints), elements and boundary conditions.
