This class treats the theories of elasticity, plate and shells, elastic stability, and dynamics of building structures as the basic theories for building structural engineering, composed of lectures and exercises.
Finite element methods (FEM) or dynamic response analyses against seismic or wind forces, which are essential for structural design, are all based on these theories, and recommended to master for not only structural engineering students, but environmental engineering and architectural planning students.
I. Master the structural theories based on the theory of elasticity and structural dynamics.
II. Fundamental formulas on elasticity, Bending and torsion of plate sections, Stress analysis and buckling of plates, Stress analysis of shells, FEM, Dynamic response theories.
Theory of elasticity, Theory of plate and shells, Theory of elastic stability, Dynamics of building structures
