BS 5977-1:1981 PDF Download

BS 5977-1:1981 is a standard that provides a method for assessing the load carried by lintels in masonry structures. The standard specifically focuses on lintels with span lengths of up to 4.5 meters for single-story buildings and up to 3.6 meters for two or three-story buildings in normal domestic use. The purpose of this standard is to ensure that lintels are able to adequately support the loads placed upon them, ensuring the structural integrity of the building.

The standard outlines the specific procedures and criteria that should be followed in order to assess the load carrying capacity of lintels. It provides guidelines on factors such as the type of materials used, the dimensions and shape of the lintel, and the design of the supporting masonry. By following the methods outlined in this standard, builders and engineers can determine the appropriate size and strength of lintels to be used in a given construction project, ensuring that they meet the necessary load requirements.
