This course is the keystone of civil engineering education and includes rigid bodies (equivalent systems of forces); analysis of two-dimensional trusses; normal and shear forces and moment diagrams in one-dimensional structures; mechanical properties: static and dynamic loading; plastic stresses and strains due to axial and shear loading and bending and torsional moments; transformations of stress and strain; multidimensional stress-strain relations; stresses due to combined loading; failure criteria; deflection of beams; elastic stability; statically indeterminate members, columns; Hook’s Law; Mohr’s circle; critical buckling loads.
