Development of a composite prestressed concrete steel structural module for the supporting elements of offshore structures. The composite structural module is composed of biaxially prestressed concrete and a steel frame surrounding the concrete. The prefrabricated composite structural modules are joined together to build a main structure by welding the steel frames. The joint between the composite modules is simpler and more reliable than those of conventional concrete structures. In the previous paper, experimental and theoretical investigations into the stresses and deformation of the composite modules during prestressing were carried out. In the present paper, are carried out experimental and theoretical investigations into the strength of the composite module under shearingforce, bending moment or combined bending and shear are carried out. Structural properties of the module were clarified through the experiments. Development of methods for the ultimate strength analysis and the nonlinear analysis using the finite element method. A comparison of calculated and observed results shows good agreement. Based on this comparison , the fundamental properties of the composite were clarified.
