# Undergraduate Course: Structural Mechanics 2A (SCEE08002)

 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 T1 Introduction and Overview: Course structure and organisation. What is structural mechanics? T2 Structural forms: Structural elements and examples. Strength and stiffness. Loads. 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. Beam stiffness T12 Superposition of Deflection Deflection coefficients. Superposition of deflections. T13 Geometric Section Properties Area, 2nd moments of area, Parallel axis theorem. Rectangular, circular, T and I sections T14 Composite Beam Sections Modular ratio and equivalent section. Stress and strain diagrams. T15 Shear Stresses in Beams (1) Complimentary shear. Derivation of shear stress formulae. T16 Shear Stresses in Beams (2) Shear flow. Rectangular, box and flanged sections. T17 Combined Loading Combining axial, torsion, shear and biaxial bending stresses. T18 Stress and Strain Transformation Plane stress, plane strain. Mohr's circle. Tutorials: 9 Tutorials (TBD) The course is examined through three coursework elements, one of which is a virtual laboratory through video recordings.

 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; andDescribe and manipulate relevant concepts of combined loadings and stress and strain transformation.
