Structural Mechanics I

Module aims

Building on the learning in Mechanics (Part 1), the aim of this module is to provide you with a basic understanding of the behaviour of common structural forms, based on a physical understanding of how these forms are able to carry external forces through the development of internal forces in structural elements. This concept is extended to derive stress and strain distributions within basic structural members. 

Learning outcomes

Upon successful completion of this module you will be able to:  
 
 
 
· Explain how trusses resist external forces.  
 
· Determine the internal forces in statically determinate trusses.  
 
· Explain how beams and frames resist external forces.  
 
· Determine the internal forces in statically determinate beams and frames.  
 
· Recognise conceptual links between structural and solid mechanics.  
 
· Determine the stresses within simple elements and cross-sections, deflections in simple beams.  
 
· Describe the concepts of designing for strength and deformation limits.  

Module syllabus

You will learn about the following topics:  
 
· Trusses: Idealisation of trusses, stability of trusses, statical determinacy of trusses, analysis of forces in statically determinate trusses.  
 
· Beams and frames: Internal forces, relationships between load, shear force and bending moment, statical determinacy of beams and frames, shear force diagrams, bending moment diagrams and axial force diagrams of statically determinate beams and frames.  
 
· Stress and strain in two dimensions.  
 
· Bending and shear stresses in beams.  
 
· Elastic deflections in beams.  
 
· Plastic theory.
