16.1　Introduction

Loads are differentiated between static and dynamic. The static loads on the structure come from gravity loads， deck loads， hydrostatic loads and current loads. The dynamic loads originate from the variable wind and waves. The environmental forces on an offshore structure can be steady or oscillating. The steady loads arise from steady winds and currents. The oscillating loads on the structure originate from the fluctuating structure motions and the waves acting on it. The steady current can also generate a fluctuating load ......     （共7386字）    [阅读本文]>>
