Description

This module has two main parts: Structural Design and Structural Analysis. Five aspects of Structural Design are covered in this module as follow:
1-Structural steelwork:
Steelwork connections: introduction to simple bolted and welded connections, geometric considerations, methods of analysis of bolt groups and weld groups

Buckling and strength of steel columns: elements subjected to axial load and bending, effect of imperfections and end conditions, columns in frames

2-Reinforced Concrete
Elastic analysis: column design – axial load and moment and slender columns

3-Composite construction:
Analysis of composite sections, effect of construction sequence on composite action, shear at interface.

4 -Timber
Structural design of timber, timber strength classes, load duration and service class, design of timber beams and joists

5 - Masonry
Materials and material properties, calculation of unit strength and mortar grade required to carry vertical loads

The Structural Analysis part consists of two aspects:
1- Analysis of simple structures:
Bar and beam system will be analgised using the matrix displacement methods based on the principle of minimum potential energy.
2-Introduction to the general Finite Element Analysis method:
2D and 3D finite element models will be developed for truss and frame structures.

The following items will be covered in the Structural Analysis part:

General expressions of strains and stresses in a bar and a beam.

General expression of strain energy of bars and beams in terms of displacement variables.

Principle of minimum potential energy.

Concept of nodes, elements, nodal displacements, nodal forces and nodal degree of freedom.

Derivation of stiffness matrices for bar element and beam element.

Transform of element stiffness matrix from local to global coordinate systems.

Assembly of element stifnness matrices.

Concept of nodal internal and external forces and assembly of nodal forces.

Learning Outcomes

By the end of the module students should be able to:

design and assess bolted and welded connections and explain the behaviour of steel columns under load

assess reinforced concrete sections at serviceability limit state

design and assess short and slender reinforced concrete columns at the ultimate limit state

design and assess steel-concrete composite beams

design and assess timber beams

design and assess masonry subjected to vertical loads

analyse statically indeterminate structures (trusses and frames) using matrix displacement methods and build the finite element analysis model for 2-D and 3-D trusses and frames.

conduct structural analyses using FEA software and understand the results obtained from the finite element analysis.
