Abstract
Many kinds of Arctic structures have been built during the past two
decades to exploit the resources of the ice-infested waters of the
Arctic region. The exterior walls of such offshore structures must be
designed to resist the high external loads exerted by the moving ice
floes and icebergs. Such structures, in addition to being economical,
should be designed to possess a high degree of safety, durability and
stability. Sandwich-type steel-concrete composite structures are a new
concept designed to resist high external loads. The composite walls are
found to be effective in transmitting large lateral forces due to ice or
earth pressure to support bulkheads (Adams et al., 1988). The basic
composite system consists of two thin continuous steel plates, placed
concentrically with a filler material such as concrete between them. The
other interesting types of steel-concrete composite structures are the
double- skin sandwich structures, in which the two steel face plates are
connected by studs with a concrete core between the steel plates. This
paper presents the load-deformation behaviour of steel concrete
composite members and their shear load-carrying capacity under static
and cyclic loads. The new parameters included in this second test
programme are steel fibre reinforcements, bar reinforcements, thin
high-strength steel face plates and stainless steel face plates. The
ultimate shear capacities of beam specimens are compared with the
calculated values using empirical and upper- bound plasticity methods
developed by the Centre for Frontier Engineering Research (C-FER). The
test results presented in this paper are from the second phase of the
experimental programme on composite members. The specimens in the first
phase were all made from normal steel and ordinary concrete without
adding any reinforcing materials, and were similar to specimen VTT-05 of
the second phase of the test programme.
