# Undergraduate Course: Structural Mechanics 2B (CIVE08010)

 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 builds upon the basic principles of structural mechanics learnt in Structural Mechanics 2A (SCEE08002). It investigates more complex types of structures, and focuses upon structural mechanics in a civil engineering context. The course describes the behaviour of beams under complex and combined loads (including moving loads), the 2D mechanics of materials, the buckling of columns, the analysis of trusses, and introduces the analysis of indeterminate structures. Course description This course follows a traditional lecture format, with weekly tutorials and a computer-based project. LECTURE TOPICS Topic 1 - Introduction to buckling - Euler buckling, bifurcation states and eigenvalue analysis - Support conditions, effective length, slenderness ratio, major and minor axis buckling. Topic 2 - 2D Stress and Strain Analysis - Stress transformations in 2D by equilibrium and using Mohr's circle; principal stresses and directions. - von Mises and Tresca failure criteria in 2D and 3D. - 3D elastic constitutive relationships; plane stress; plane strain. - Mohr's Circle for Strain. Strain gauge rosettes. Topic 3 - Introduction and Trusses - Course structure and context. - Truss analysis using the method of sections and the method of joints. Topic 4 - Beam deflection - Discontinuities of loading and use of Macaulay bracket analysis to determine beam deflection under various load cases. Topic 5 - An introduction to statically indeterminate structures. - Determinacy and compatibility in simple beams. - Indeterminate analysis by superposition. Topic 6 - Moving loads and load combinations. - Influence lines for reactions and stress resultants. - Influence lines for trains of loads. - Moment envelopes for indeterminate beams. TUTORIALS T1 Warm-up exercises T2 Buckling of columns T3 Stress transformation and failure criteria T4 2D elasticity and strain transformation T5 Analysis of trusses T6 Deflection of beams T7 Simple redundant beams T8 Moving loads and load combinations PROJECT EXERCISE A project that explores the concepts introduced in lectures and refers to buckling. Each student is required to submit a project report.
