# Undergraduate Course: Structural Mechanics 2 (CIVE08026)

 School School of Engineering College College of Science and Engineering Credit level (Normal year taken) SCQF Level 8 (Year 2 Undergraduate) Availability Available to all students SCQF Credits 10 ECTS Credits 5 Summary This course engages students with the fundamental principles of Structural Mechanics relevant to civil and mechanical engineers. Specific topics including: equilibrium, stress, strain, axial load, torsion, bending, shear, and deflections in structural elements including beams, columns, struts, ties, and trusses. Course description Lecture Topics: - T1 Introduction and Overview: Course structure and organisation. What is structural mechanics? - T2 Structural forms: Structural elements and examples. Strength and stiffness. Loads and factors. - T3 Global Equilibrium: Forces and moments, point and distributed loads. Support conditions. Global equilibrium of structures. Concept of structural determinacy and indeterminacy. - T4 Free Body Diagrams and Stress Resultants Truss equilibrium. Stress resultants in struts (axial load), shafts (torsion), beams (shear and bending) and pressure vessels (membrane forces). - T5 Members carrying Axial Load Simple mechanical behaviour. Deformation (due to load and thermal strain). - T6 Members carrying Torsion Torsion of circular shafts and other closed sections. Torsional stiffness and deformation. - T7 Stress Resultants in Determinate Beams (1) Sign conventions. Shear force and bending moment diagrams. - T8 Stress Resultants in Determinate Beams (2) Relationships between w, V, and M - T9 Bending of Beams (1) Euler Beam Theory. Curvature. Plane sections. Bending strains - T10 Bending of Beams (2) Euler Beam Theory. Elastic bending stresses. The neutral axis. Moment - curvature - stress - strain relationships. - T11 Deflection of Beams Double integration of curvature to find deflection. Support boundary conditions.

 On completion of this course, the student will be able to: Describe and manipulate fundamental concepts of stress, strain, and deformation in members carrying axial, bending, shear, and torsional loads;Determine how statically determinate trusses and beams carry load; for beams using diagrams of bending moment and shear force, and evaluate the resulting elastic deflections of the beams;Analyse structural cross sections, so as to determine the elastic stress and strain distributions, as well as the deformations, resulting from axial, bending and torsional actions;Describe and manipulate relevant concepts of combined loadings and stress and strain transformation.
