... ABSTRACT The design of topsides for offshore structures must consider the accidental release of the hydrocarbons and the possibility of resulting explosion. The estimation of the explosion loads on the topside structural systems is a complex task as it involves several sources of uncertainty...

... ABSTRACT After the Mega-Float project was completed on March 2001, its utilization of the concept of the Mega-Float considered to be foundation of building has been attracting authors. Assuming that the base was constructed by plate structural system and building was made by framed structural...

... of the main structure is a newly developed device that could effectively reduce the vibrations for many kinds of structure. Therefore, an intuitive concept to apply the TLCD to the offshore structural system was carried out for this study. In the results of feasibility studies it is found that the accurately...

... Abstract Structural systems that can sense and adapt to the environment automatically offer new vistas for designers and lead to novel efficient developments. An offshore structure is defined as smart when sensor, actuator and even controller become integral part of the structure or structural...

... ABSTRACT This paper addresses the practical application of a multiple-input-single-output nonlinear system identification technique on ocean structural systems. An ocean structure exhibiting nonlinear behavior due to geometric nonlinearity of mooring line angles and the complexity...

... for the larger structural system. Traditionally, the assessment of structural integrity has been carried out via the application of simplified analytical models that are defined for various modes of failure for the stiffened panel configurations. Later on, sophisticated analytical techniques such as the finite...

... ABSTRACT A procedure is presented for the ultimate strength system reliability analysis of offshore structures. The structural system reliability model is generated through a so-called Critical Path Incremental Loading Procedure in which incrementation is performed along a failure path...

... to be directed toward the development of general, application-oriented optimization systems. Challenged by the complexities involved in shape and lay-out optimization of structural systems, this direction drives the emergence of concepts which integrate mathematical programming, finite element and sensitivity...
