 SHE Level 3 SCQF Credit Points 20.00 ECTS Credit Points 10.00 Module Code M3H224596 Module Leader Martin MacDonald School School of Computing, Engineering and Built Environment Subject SCEBE - School Office Trimesters A (September start) B (January start)

### Pre-Requisite Knowledge

Engineering Mechanics

### Summary of Content

The aim is to provide the student the knowledge and understanding of the design of steel structures based on the British standard specifications. In this module, structural analysis and structural design of steel structural elements will be explained. This module also gives an insight into the way in which the structural elements function, the work of each structural component and their performance when they are assembled to form a structure. Further, Plastic analysis of structures will also be explained which is the basis for the development of Limit State Design of steel structures in understanding the load carrying mechanism of steel structural elements.

### Syllabus

The teaching syllabus will cover the following areas: - Introduction to Structural Steel Work: Properties of structural steel, Structural Steel Design to BS 5950,Simple Design, Continuous Design: Semi Continuous Design, Structural loadings as per BS: 6399. - Introduction to Limit state design of steel structures: BS 5950 provisions, Robustness of Structural Frames, Limit state of serviceability- Deflection, Classification of Structural Sections, Design of Steel beams as per BS 5950 -Lateral restraint of compression flange, Full lateral restraint, Intermittent lateral restraint, Torsional restraint, Degree of fixity at end supports/stability of loading, Practical Beam Design, Restrained beam, low shear load, Fully restrained beam High shear load, Beam not fully laterally restrained, examples on design of beams . - Design of Compression Members: Slenderness, Effective lengths, Compressive resistance, Compression members with moments, examples on design of compression members. -Design of Steel Column Splices and Base Plates: Examples of column splices, Column Base plates, Base Plate design, Axially loaded base plate: Size and thickness. Base plate in bending: size and thickness, Base plate in bending, tension developed, examples on design of column splices and base plates. - Connections: Bolted Connection -Minimum spacing, Maximum spacing in unstiffened plates, Minimum edge and end distances, Maximum Edge distance, Maximum Edge distances for bolted connection ,ordinary bolting, Shear capacity, Bearing Capacity, Bolts subjected to tension, Welded connections-Fillet welds, Intermittent fillet welds, Moment resisting connections-Applied moment in the plane of the connection. Bolted connection and welded connection, Applied moment perpendicular to the plane of the connection - Bolted connection and Welded connection, Design examples on bolted and welded connections. -Design of Steel Plate Girder: Structural design of welded steel plate girders as per BS: 5950 provisions - Serviceability limit states, Flange buckling limit,- sizing of trial section, top flange fully restrained, top flange un-restrained, or restrained at intervals, check for deflection under live working loads, check for bending strength and check for shear. Design example on welded steel plate girder. -Plastic analysis of structures: Introduction to plastic analysis of structures, plastic hinges, analysis of simple beams for plastic moments.

### Learning Outcomes

On completion of this module the student should be able to:- Determine the critical loads and derived bending moments in themembers of simple structures[A1,A2,A4,B1,B3,B4,C1].- Design simple elements (e.g. beams, columns, and bases) in structuralsteel using current Limit State Design Standards, BS5950. [A1, A2, A3, A4, B2, B3, B4, B7, C1, C3]- Ensure that structural behavior in practice corresponds to the assumptions of the design model by appropriate detailing of thestructure. . [A2, A4, A5, C4]- To have an understanding of the plastic analysis of structures. [A1,A3,A5,B7].

### Teaching / Learning Strategy

The main teaching method will be based on class room lectures using teaching aids like over-head projector slides and power point presentations. Site visits for better understanding of the design concepts taught in class room by virtual visualization of the structural steel members' fabrication and their assembly in the structure. The students will be expected to perform directed reading and self-learning exercises and enhance their structural analysis and design capabilities. Tutorials will be used to reinforce the module material and to discuss the issues raised by the directed reading.
