Study-Unit Description


TITLE Structural Analysis 1

LEVEL 05 - Postgraduate Modular Diploma or Degree Course


DEPARTMENT Civil and Structural Engineering

DESCRIPTION This study-unit focuses on the analysis of linear skeletal frameworks. In the first instance, it highlights the difficulties of "rigorous" analysis of indeterminate structures, and the importance of approximate analysis of indeterminate structures, such as continuous beams, plane frames, vierendeel girders, first of all for the purposes of preliminary sizing in design processes, but especially for the verification of analytical models and the final analyses. The substantial difference between elastic analysis and real behaviour is emphasized. The study-unit further develops the theoretical analysis of indeterminate skeletal frameworks, on the basis of both elastic and plastic approaches.

Study-unit Aims:

The study-unit aims to offer students a sound grounding on the principles for the solution of indeterminate structures, using flexibility and stiffness approaches. It aims to address classical as well as matrix methods of structural analysis. It highlights the use of energy theorems in structural analysis, focusing on virtual work and deflection calculations, and on the use of influence lines to assess moving loads. The study-unit aims to offer an insight to plastic analysis of indeterminate framework structures, and the use of the concept of static-kinematic duality in understanding the different ways by which "true" solutions of structures can be achieved. The study-unit will, however, also emphasize approximate methods of analysis, and qualitative structural behaviour.

Learning Outcomes:

1. Knowledge & Understanding:

By the end of the study-unit the student will be able to:
- Recognize the need for approximate analysis for initial sizing and verification of structural analysis;
- Identify the key difference between determinate and indeterminate structures and the need to satisfy equilibrium and compatibility simultaneously;
- Recall pre-computer methods of analysis, or classical methods of analysis;
- Discuss the theoretical basis of modern computer methods of analysis, and identify intrinsic approximations;
- Formulate the basic theorems of rigid-plastic analysis;
- Examine the material and geometric causes of non-linear behaviour in structural systems;
- Synthesize the relationship between idealised elastic/plastic behaviour and behaviour in practice for structural elements and systems, and the implications for the behaviour of columns and beams.

2. Skills:

By the end of the study-unit the student will be able to:
- Apply the understanding of structural behaviour to simplify structures to allow determine approximate forces, moments etc;
- Draw the diagrams for deflected shape, bending moments and shear forces for a range of two-dimensional framework structures;
- Explain the structural significance of points of contraflexure, hinges and partial releases;
- Use specific methods of pre-computer (classical) methods of analysis of an indeterminate framework structure;
- Undertake rigid-plastic analysis of continuous beams and simple portal frames.
