Knowra Structural analysis Structural analysis Structural analysis calculates the forces, stresses, and deformations that loads produce in structures. It predicts how structural systems respond and whether they meet safety and serviceability requirements.
Equilibrium of forces : The condition in which the net force and net moment on a body are zero. Equilibrium equations are the starting point for finding unknown reactions and internal forces.
Statics : The branch of mechanics that studies bodies in equilibrium under forces and moments. Most introductory structural calculations apply statics to supports and internal forces.
Structural engineering : The engineering discipline concerned with designing and assessing structures that resist loads safely. Structural analysis is a central tool within this broader design discipline.
Matrix structural analysis : A formulation of structural behavior using matrices of stiffness, displacement, and force. This systematic formulation underlies many computer-based analyses of frames and trusses.
Boundary conditions : Constraints or prescribed values that a mathematical model must satisfy at its boundaries. Supports and connections become boundary conditions that shape the calculated response.
Strength of materials : The study of how solid materials deform and fail under applied forces. Its stress, strain, and deformation relations supply essential structural model behavior.
Bridge engineering : The engineering of bridges, including their design, construction, and maintenance. Bridge spans and supports are analyzed for traffic, wind, temperature, and other actions.
Plastic analysis : A method that predicts structural capacity by tracking yielding and formation of plastic hinges. Unlike elastic analysis, it can estimate collapse loads beyond first material yield.
Finite element method : A numerical method that approximates solutions to differential equations by dividing a domain into smaller elements. It lets analysts calculate complex structural responses by assembling element-level equations.
Stress (mechanics) : Internal force per unit area within a material, described by a tensor at each point. Stress measures the internal intensity caused by the loads being analyzed.
