When used as roof and wall claddings, sandwich panels can offer many advantages such as better appearance, thermal insulation and strength. They can also develop a significant stressed skin action that can be used to resist wind loads on portal frame buildings. However, this beneficial effect is generally ignored by Australian designers since roof claddings are crest-fixed. To utilise this effect, a suitable design methodology and associated strength parameters must be developed. This paper investigates the possibility of combining three dimensional computer modelling with the results of a detailed experimental program to produce economical and safe portal frame buildings with crest-fixed sandwich panels. A design method is presented along with guidelines for three dimensional computer modelling.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
