ABSTRACT
Environmental loads that act on marine structures are not completely deterministic; only a few features of the loads are known (Ang and Tang, 1975a). Some of the examples of such loading are extreme waves, sea bed movement, wind loads on super structure, ice loads, impact loads caused by vessels, etc. Apart from these loads being random in nature, they also have a high probability of exceeding the safe design limits, which can cause an overloading situation (Benjamin and Cornell, 1970). In addition to the above, at all stages of construction of marine structures, there is high degree of uncertainty with regard to geotechnical problems that are site-specific (Chandrasekaran, 2013a,c; Chakrabarti, 1987, 1990). This shall transfer the complexities to a different level that uses a set of expressions to obtain the desired design quantities such as ultimate load strength, capacity of joints under different load combinations, additional stresses induced due to corrosion, etc.
