Abstract
This paper examines a method of numerical simulation of 3-leg jackup response to horizontal load. The method assumes variable rotational (moment) fixity, variable horizontal fixity, and complete vertical fixity. Numerical results are compared with centrifuge model test data. Consistently with Wong et al. (1993), it is shown that moment fixity increases with increasing spudcan rotational stiffness, increasing leg length, and decreasing leg flexural rigidity. It is further shown that fixity degrades with increasing horizontal load. Fixity with a longer leg under high horizontal load may become smaller than fixity with a shorter leg length under low horizontal load.
