Fea on interaction of super structure , raft foundation and ground base 筏板基础和地基共同作用的有限元分析
Due to the vibration feedback from super structure , the motion of foundation is different from that of free field 上部结构柱顶加速度反应主要由基础转动引起的摆动分量组成,平动分量次之,而弹性变形分量很小。
Firstly , several main enterprises are selected as units of the network . then some new candidates are inducted into the super structure network 选取园区的数家重点企业,并适当引入一些新企业单元,构成氯集成的研究对象。
The steel - structure girder has been widely adopted as the super structure of extra - long span bridges , because of its hypertension , gigantic - stiffness , light - weight and convenience of construction as well 钢结构梁因为强度高、刚度大、自重轻、施工便捷等特点,作为特大跨径桥梁优选上部结构,被广泛采用。
Then the unit models are combined into a super structure network model for mass integration . the network model includes matrices of data , environmental or economic constraints and objective functions 本文提出了物质集成模型的变量表达方法,分析了物质集成模型的约束条件和目标函数,最终构建了物质集成的一般性方法。
( 2 ) also , we discuss how to set up a hydrogen network super structure and a optimization model of oil refineries . the advantage of the super structure is considering suppliers , consumers , purifier , compressors , pipes and pressure constraints , and connecting all possible links from sources to sinks ( 2 )本文讨论了炼油厂氢网络子系统超结构的构建和优化方法,综合考虑了氢系统的供氢装置、耗氢装置、提纯装置、压缩机、管网,以及系统压力的约束条件,建立了所有可能的氢源与氢阱之间的连接。
