In the construction industry, advanced and highly innovative building projects are being constructed nowadays. It is important to ensure that such unique and unusual projects stand strong, durable, and harmless in adverse conditions. That is why structural analysis is important and comes into action. In this article, we are discussing about linear structural analysis and nonlinear structural analysis . We will be discussing the software programs used by professionals (belonging to the construction industry) to analyze the structural designs and details. Let us begin with linear structural analysis. Linear Structural Analysis It is basically an analysis where a linear relation holds between applied forces and displacements. In this process of analyzing, experts look after all the structural problems and rectifying them to prevent future mishaps. In structures, stresses remain in the linear elastic range of the used material. And, in the linear static analysis, the mo...
