Eurocode 5: Timber Design

Eurocode 5 : Timber Design

Introduction

Eurocode 5 offers opportunities to structural engineers designing in timber. The existing code, BS 5268, is a permissible stress code. The new Eurocode is a Limit State code. In separating the serviceability limit state from the ultimate limit state it presents design in a format consistent with the existing steel and concrete codes but it needs care in use. To ensure a safe design, the code must be applied with care in using the correct load, material and modification factors.

This course will introduce timber engineering and explain the significant parameters in the Eurocode. It will show how to design to Eurocode using the recently published TRADA / IStructE Manual to EC5.

Course Content:

Timber

• Background to properties of timber.
• Properties of timber materials (grading, duration of load, specification, design.
• Parameters, availability of materials, dimensions and tolerances, workmanship).

Eurocode 5 - Basis and Principles

• Normal design, fire design and bridges introduction to codes.
• National Annexes and Non-Contradictory Complementary Information.
• Materials, partial factors and modification factors.
• Ultimate limit states - normal and accidental conditions.
• Serviceability limit states - deformations, creep and vibration.

Eurocode 5 - Detail Design

• Flexural members (beams)
• Compression members (columns)
• Connections - nails, screws, bolts, dowels and connectors
• Engineered timber
• Fire
• Durability.

Professor Richard Harris, BSc, CEng, FIStructE, FICE, AIWSc, part-time Professor of Timber Engineering at the University of Bath. Technical Director with Buro Happold in Bath. Practicing structural engineer leading a team of engineers in the design of structures in differing sectors and using differing construction methods and materials. Specialising in the field of Timber Engineering his wide range of timber engineering projects include the Downland Gridshell and the Savill Building (winner of the 2007 IStructE Supreme Award). Professor Harris chaired the Task Group for the Institution of Structural Engineers, for the IStructE/TRADA Manual for the Design of Timber Building Structures to Eurocode 5.
