Shear Strength of Sandwich Panel Systems
Administrators only | Request a copy from author
The use of sandwich panels as roof and wall claddings has increased considerably in recent times. For the designers to take advantage of the diaphragm action of stronger sandwich panel systems under in-plane shear forces due to wind loading, appropriate data on shear strength and stiffness of these systems is required. An experimental investigation was therefore conducted to investigate the shear behaviour of commonly used crest-fixed sandwich panel systems. An improved fastening system was developed which resulted in approximately 2.5 times greater shear strength, and improved ductility. Shear strength and stiffness data were developed for sandwich panel systems with the improved fastening system for varying aspect ratio. Analytical formulae were also developed to predict the shear strength of sandwich panel systems using the basic tearing loads obtained from simple connection tests. This paper presents the details of both experimental and analytical studies on the shear behaviour of sandwich panel systems and the results.
Impact and interest:
Citation counts are sourced monthly from and 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.
Citations counts from theindexing service can be viewed at the linked Google Scholar™ search.
