摘要
建造于渤海的平台结构应具有较大的刚度,以利于抗冰,但这也招致了更大的地震荷载。后者往往超出前者成为结构设计的控制条件。为此,研制了一种具有双重刚度的新型平台结构,它能同时满足抗冰和抗震对结构刚度的不同要求,就是说,海冰作用时它的刚度是大的,地震力作用时它的刚度又是小的,详情请见本文介绍。
Platforms built for use in the Bohai Gulf are required to have great rigidity to resist ice loads, as a result of which this leads to greater earthquake loads. In these cases earthquake loads exceeds ice loads and become dominant loads of structural design. For this reason, a new kind of dual-rigidity structure has been developed, which will meet the requirements of resisting both ice loads and earthquake loads,and under ice loads it provides great rigidity and under earthquake loads there is less rigidity. The details are described in this paper.
