1.2 Contents of this guide

What you will find in this guide:

This guide provides information on how to design and build simple roof structures for lightweight and even (non-curved) roof cover materials. Although it was originally compiled as part of the FCR/MCR Toolkit series only, it is equally applicable in the case of other roof cover materials such as clay tiles, slates, sheets etc.

- In a popular rather than in a scientific way the principles of basic building statics are explained, providing a general understanding of the forces which occur in buildings and their implications on the structure.

- Various aspects that determine the design and shape of roofs are explained. These include climatic aspects and the interrelationship between the floor plan and roof shape.

- Principles of structural design are explained. A step-by-step approach explains how to develop the design of the structural elements.

Aspects of earthquake proof and storm proof construction are also included.

As timber is still a material which is widely-used in roof structures, it is dealt with in detail.

A handy method for sizing the main timber elements for simple roof structures is provided, taking into account the varying strength properties of different timber species. The method can be used where standard values are not available.

Other alternative materials for roof structures such as timber trusses, bamboo, pole timber, metal and concrete are dealt with briefly. For detailed information specialised literature or pro-fessional advice should be consulted.

- Finally, methods and practical hints for the construction process as well as maintenance are provided.

- The appendices contain conversion factors for roof slope measures, an extensive list of timber available in different regions with their main characteristics, tables for sizing structural timber (sawn timber and pole timber), and a list of selected literature.

What you will NOT find in this guide:

The guide is not a scientifically-comprehensive textbook, but is rather designed for practical application.

It does not focus on free and complicated forms in roof design which require a greater degree of expertise, skill and practical experience.

It also does not contain

- Information on production management

- Specifications with regard to costs and profit

- Information about particular problems in specific countries

- Truss-making

- Guidelines for the production of tiles

- Guidelines for quality control of tiles and the required tests

- Information about roof cover and its detailing

For information on these aspects please refer to the other toolkit elements in this series. (See Toolkit Overview on the front page)
