摘要
杭州湾跨海大桥海中平台结构由浅海高桩平台、上部多层框架以及屋顶异形三层网架组成,结构形式复杂,整体分析难度大。本文着重介绍了采用合理的假定以及简化,用整体结构分析的方法完成对这种特殊结构的分析计算,并与水工专业的分析结果进行了比较,认为是合理可靠的,对同类结构的分析处理有一定参考作用。
Taking the Hangzhou Bay Sea-Crossing Bridge offshore platform as an example,the integral analysis of a kind of multi-storey steel building with triple-layer space trusses is introduced.Considering the characters of the platform,by assumption and reasonable predigestion,the platform structure is analyzed and results are compared.The analysis experience can be a reference for similar engineering.
