Light-gauge profiled steel claddings can act effectively as structural diaphragms and in so doing can enhance a building’s performance. Much work has been done overseas to establish standards, codes of practice and design guides in this field. Unfortunately, few of these are readily applicable in New Zealand because of differences in local products and practices.
This review forms the first part of a research programme aimed at establishing the appropriate guidelines and to provide basic data for using such diaphragm action in New Zealand.
The aspects covered include the modes and conditions of diaphragm action, New Zealand and overseas practices as well as developments in design overseas. Future work needed to achieve the aim is discussed.
