Timber Engineering Notebook series. No. 12: Cross-laminated timber construction – manufacture, detai

This Timber Engineering Notebook introduces the checks for overall building stability and those required for the wall diaphragms which provide shear (or racking) resistance to a platform timber frame structure.

Our built heritage is a finite resource stretching back thousands of years. Protecting and conserving this heritage is a challenge requiring knowledge, skills and experience, together with an ability to bring practical engineering judgement and often creative and imaginative solutions. This paper sets out the challenges faced by engineers and some of the approaches taken in the appraisal and protection of ruins.

Structural insulated panels (SIPs) are engineered, load-carrying, timber-based panel products that can be used in walls and roofs of residential and light commercial buildings. These lightweight panels combine the structural and thermal envelope of the building; they are manufactured offsite in a factory and shipped to the construction site, offering advantages to the build programme. This panelised form of construction allows SIPs to be assembled to form highly airtight, energy-efficient building envelopes.
