Calculated loadbearing brickwork is discussed and the basic requirements are specified. Materials and their effects on strength andperformance are considered and recommendations made.
Following the publication in 1964 of the Joint Committee report Fully-rigid Multi-storey Welded Steel Frames, an experimental investigation was instituted aimed at establishing the accuracy of the simplified design method proposed therein. This investigation took the form of tests on a full-scale 3-storey 2 bay X 1 bay rigid-jointed frame fabricated in BS 4360, Grade 43 steel, and designed in accordance with the recommendations of the report. The results of these tests were presented in a paper in The Structural Engineer.

It is now a requirement under the Building Regulations that structures of five storeys and over should remain stable following the removal of a specified length of loadbearing wall, although at a substantially reduced safety factor. Three experiments are described in this paper which had the object ofproviding confirmation that this could be achieved in a simple five-storey brickwork cross-wall structure. In each test a section of loadbearing wall was removed and measurements were made of applied loads, deflexions and strains. The theoretical conclusion fhat the structure would remain stable under these conditions was confirmed and some information was obtained concerning the strength of 114 mm (4.5in) thick wall panels subjected to lateral loading.
