ENGINEERING TRIPOS PART IIB - 2012/2013

Module 4D7 - Concrete and Masonry Structures

AIMS

This module aims to carry further the basic material on reinforced concrete studied in Part IIA, to treat such matters as durability and corrosion, design of beams, slab, columns and frameworks (for shear and torsion as well as bending), covering masonry structures where appropriate, but leaving prestressed concrete to module 4D8.

LECTURE SYLLABUS

(Lecturer: Dr C.T. Morley)

Background to cement and concrete (1L)

• Recent developments

Limit state design (1L)

• Probability concepts: partial safety factors (brief survey)
• Failure case studies.

Material properties (2L)

• Hydration and strength of cement paste;
• Uniaxial properties of concrete;
• Concrete under multiaxial stress.

Durability (2L)

• Net Present Value: whole life costing;
• Deterioration of concrete;
• Water migration through concrete; concrete in fire (brief mention)
• Corrosion of steel in concrete; preventative measures.

(Lecturer: Dr C. Middleton)

Reinforced concrete structures (6L)

• Serviceability: crack widths, deflections (revision)
• Initial sizing of members (revision of 3D3)
• Beams, slabs and frameworks at ultimate limit state;
• Column design, instability;
• Shear failure (and fracture mechanics);
• Truss analogy, torsion;

Masonry structures (2L)

• Properties of masonry;
• Blockwork in compression, wall design;
• Arches, lines of thrust, plasticity theory.

COURSEWORK

This will consist of two parts (i) witnessing experimental laboratory techniques in the context of reinforced concrete testing, plus short write-up, and (ii) a short design exercise.

OBJECTIVES

On completion of the module students should:

• Have good basic appreciation of the constituents and properties of concrete and masonry;
• Understand deterioration processes affecting reinforced concrete, and how to control them;
• Be able to analyse simple concrete structural components and frameworks, and design them to practical requirements;
• Be aware of the properties of masonry, and understand simple analysis and design of masonry structures.
