tailieunhanh - Analysis for Civil Structures

The analysis model of a structure includes nodes (joints), elements and boundary conditions. Finite elements are used in data entry, representing members of the structure for numerical analysis, and nodes define the locations of such members. Boundary conditions represent the status of connections between the structure and neighboring structures such as foundations. A structural analysis refers to mathematical simulations of a numerical analysis model of a structure. It allows the practicing structural engineers to investigate the behaviors of the structure likely subjected to anticipated eventual circumstances | Analysis for Civil Structures INDEX 1.
