Static and Cyclic Tests on Composite Ice-Resisting Walls: The Second TestProgramme

摘要

Sandwich-type composite structures consist of steel face plates connected to eachother with vertical plates and of concrete core casted between the face plates. The research study looks at the load-bearing capacities and practical applications of these new type of structures. The first part of the study considers mainly Japanese, Canadian, American and British research results. Further, practical applications of sandwich-type composite structures built for different loading cases and environments are listed and design and calculation codes under consideration are studied. The main part of the research forms a direct continuation to the experimental studies carried out in the Laboratory of Structural Engineering during 1988-1989. During this present research project a total of 14 specimens were tested. New parameters analyzed were steel fiber and steel bar reinforcement in the concrete core and thin-walled high-strength and stainless steel in the face plates of the specimens. The comparison between the experimental results and the calculated results indicated some development needs in the calculation models available today, especially in the case of thin-faced specimens.
