CENV3056 Structural Engineering

Module Overview

This module aims to provide a detailed understanding and practical application of methods of structural analysis and design to approved codes of practice relevant to typical steel and concrete framed buildings and bridges with supplementary studies in timber and masonry materials. An additional understanding pertaining to the appropriate use of advanced analytical methods will be provided complementary to core study objectives. This module will build on the content of Part 2 CENV2024: Structural Design and Materials to cover the conceptualisation and detailed design of beams, columns, slabs and connections in reinforced concrete and steel incorporating limit state principles.

Aims and Objectives

Module Aims

The primary objective is to equip students to either graduate at BEng level with all the basic tools required to design these types of structure in professional practice, or to continue to MEng level to gain a deeper understanding. Detailed reference will be made to the latest Eurocode design standards.

Syllabus

Introduction and understanding of the Eurocodes. Application of limit state theory to structural design. A complete understanding relating to the comprehensive design and detailing of (flexure, shear, local and global buckling):steel beams, steel columns, base plates, lateral torsional buckling effects, steel welded connections, steel bolted connections, reinforced concrete beams and slabs, reinforced concrete columns, reinforced concrete concentrated shear effects. The incorporation of conceptualisation and provisional element sizing as a design tool is covered in depth (also forming part of the final examination). Additional LUSAS tutorial series will include: Session 1: Getting started/ beam models: Creation of points and lines, defining and assigning attributes. Using view tools and drawing layers including diagrams. Standard section property calculator. Loading options. Envelopes & combinations. Connectivity and basic checklist. Examples: Roof truss (guided) and arch bridge (workshop-style) Session 2: Plates and shells: Plate and shell elements. Creation of surfaces. Discrete point and patch loads. Contoured results, graphing and user defined results. Mesh refinement. Example: flat slab (guided), circular tank (hands on) Session 3: Mixed beams & shells (inc basic dynamics) Mixing element types. Use of offsets. Natural frequencies & animation tools. Stress concentrations. Constraint equations. Example: Building floor (with columns) Session 4: 2D & 3D continuum: Continuum elements: 3D, plane stress, plane strain, axisymmetric. Generating 3D geometry (import or draw). Structural idealisation - choosing the best approach. Example: Box culvert (plane strain) or circular tank (axisymmetric) Example: Box culvert (plane strain) or circular tank (axisymmetric) Session 5: Buckling: About buckling; Local and global buckling; analysis approach. Elastic (eigenvalue) buckling and NL buckling. Example: 3D girders using shell elements with elastic buckling

Special Features

A wide range of feedback is employed including guided tutorials, structured problem solving and online quizzes to measure your learning. There is also a guest lecture and a field trip to the Weald and Downland open air museum. Much of the site is accessible via wheelchair but some buildings have narrow staircases and due to their age no lifts. The museum has a panoramic photo library of the upper floors of such buildings.

Learning and Teaching

Teaching and learning methods

Three weekly lectures: (i): formal theory and best practice, (ii): applied design examples, (iii): guided tutorials with feedback. Examples of international flag-ship projects in structural design: illustrative scheme designs and reference case studies. Taught material is reinforced through structured problem solving, feedback and additional sources of reference information. Conceptual design and sizing of key structural elements using 'rules of thumb' for feasibility stages and outline design is considered in parallel. Video examples of inspirational structural design projects, materials science and key detailing concepts are shown throughout the lecture delivery to aid understanding and foster a wider interest in the subject; placing the study materials in contemporary context. Field visit to the Weald & Downland Open Air Museum to study period structural design and construction in a broad range of natural materials, including the UK's first timber gridshell. Guest lecture in week 5 from external invited speaker: Director of Health & Safety, briefing on diligent measures for structural engineers. Intensive six week, professionally delivered tutorial series focusing upon the correct and diligent use of FEA for structural design - skills in LUSAS structural analysis software will be taught to aid students in future project studies and further career development. LUSAS learning will be cross matched to core study materials and assessment methods.
