The Stability of a Five-storey Brickwork Cross-wall Structure Following the Removal of a Section of

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.
