Abstract: An energy-supply rotary inertia driver system for an offshore platform includes an annular fixed plate, an active control module, a wind power generation module and a solar power generation module. The system can monitor a motion state of the offshore platform in real time, and can generate a force through the active control module if necessary to apply a force torque of the offshore platform to further achieve the vibration suppression. Moreover, when the offshore platform is under normal operation, the system can act as an energy supply device via wind and solar power generation to feed electric energy to the active control module and other electrical equipment on the offshore platform when needed.

Abstract: A prefabricated steel-wood composite joint includes square pipe columns, steel-wood composite beams, and a beam-column connecting assembly for connecting the square pipe columns and the steel-wood composite beams. Each square pipe column includes connecting corner columns and connecting side plates. Each steel-wood composite beam includes a top flange, a bottom flange and wood webs for connecting the top flange and the bottom flange. The beam-column connecting assembly is a central column connecting assembly or a corner column connecting assembly. By a special structural design, the composite joint realizes effective beam-column connection without a welded connection and a bolted connection and has tenacity and good seismic performance. The components of the composite joint can be prefabricated in a factory, are high in precision and are assembled on site, so that construction is easy and convenient, procedures are simplified, and the construction period is effectively shortened.

Abstract: A method for assessing a performance-based seismic design by setting a seismic risk starts from the exceedance probability of the performance level. The method is configured to determine the structural performance level by setting an exceedance probability, determine the seismic demand when the performance level is constant, set the exceedance probability of the seismic demand in combination with the seismic risk of a set earthquake to finally determine the ground motion input and establish a novel probabilistic seismic risk assessment method that reaches the performance level. The main control and objective of the design are significantly enhanced by using this method.
