上部结构

• The results show that the energy response has an important effect on the slipping isolator efficiency of the vibration characteristics of the structure
  结果表明，滑移隔震对于上部结构振动响应的隔震效果受能量方面的机理控制。
• The common work of pile - soil - structure is regarded to an entirety , and should meet the coordination condition on contact side each other
  桩-土-上部结构的共同作用是把三者看成一个整体，并要满足相互之间在接触部位的变形协调条件。
• Also the concrete structure ' s service life may be threatened by the negative pressure occurred when waves se parate from the subface of the structures
  另外当波浪离开上部结构底面时产生的负压力作用对混凝土结构的耐久性也是一个很大的威胁。
• But structure and foundation is an organic system , and if separate them artificially , it will lead to considerable torsion to the result of earthquake response
  然而上部结构和地基基础是一个有机整体，人为地将其分开有时会给地震反应计算结果带来较大失真。
• In china , especially since the 1990s , steel - structures have been introduced into a lot of grand bridges which spanned over roaring rivers and surging seas
  特别是上世纪九十年代以后，在我国修建的一系列跨江跨海特大型桥梁中，很多桥梁上部结构采用了钢结构。
• Furthermore , geometrical sizes of superstructures are easier to perform . 2 . the prefabrication of superstructure segments can be processed while the substructure is under construction
  ( 2 )施工速度快，工期短；上部结构节段预制可与下部结构施工同时进行。
• The non - linearity of the foundation can be analysed by the factor of the raft - pile interaction . moreover , a factor behaviors of over consolidated soil is used
  该法将基础承担上部结构的过程划分为3个阶段，用桩筏相互作用系数对沉降控制复合桩基作非线性分析。
• The cancellation of web bending reinforcement and continuous bar in upper structure of continuous rigid frame bridge is discussed with mechanics method . 4
  并对连续刚构桥上部结构设计中取消腹板弯起索、下弯索和连续束问题进行了探讨，从力学角度进行了分析研究。
• The design works of top - part structure of qing liang jiang bridge was according to the requirements of proposal and regulated issues / regulations after the comparison of various designs
  本设计是根据设计任务书的要求和相应规范的规定,对清凉江桥上部结构进行方案比选和设计的。
