摘要

Worldwide practice (Norway, England, USA, Canada, etc.) has revealed the advantages of application of concrete structures for offshore platforms. At the same time, experience gained in the application of the concrete-filled steel and reinforced concrete structures for ice-resistant platforms cannot be used directly. Rational design of concrete-filled steel structures, requires analysis of a great number of structural cases, which in turn requires a large number of cases to be calculated. This paper presents an engineering procedure for estimation of the stress and strain state that avoids the use of complicated finite-element models and still defines a range of rational options for offshore ice resistant fixed platforms (OIRFP) of concrete-filled steel type to be further analysed in details using various software realising the finite element method.
