Thin-walled steel sheets with indentations in composite steel-concrete structure under different types of loading

摘要

This article is focused on a special type of thin-walled steel sheets with shear connection. These are especially suitable for roof and floor-bearing structures, allowing the building process to be easy and fast. The shear connection between the sheet and the concrete, which is realised by moulded dimples, ensures the composite action of the steel and concrete material without any need of additional reinforcement. In this article you can find a short review of thin-walled sheets, which are manufactured in Western Europe, and results from our experimental testing of specimens. These specimens were tested by vacuum loading and by cyclic loading in four-point bending tests.
