OFFSHORE APPLICATIONS OF HIGH STRENGTH CONCRETE SPACE FRAME

The paper presents the results of studies on the offshore application of concrete trusses and space frame techniques including a Concrete Module Support Frame for a North Sea Gravity Based Structure, a Concrete Module Structure and a Concrete Space Frame Roof for subsea cells. After a brief historic review of triangulated structures, the use of concrete trusses is illustrated with the presentation of the main features of three civil works realisations, showing the evolution of both design and construction methods. Emphasis is placed on the correlation of the space frame technology with development of high-strength concrete.
