Some engineering problems are caused by ground unequal settlements. In order to investigate the influence of the ground unequal settlements on the superstructure, a finite element method simulating ground(or pile ground) is developed by three-dimensional elastic support, which could integrally analyze the interaction among structure, foundation and ground. The comparative analysis among three-dimensianal elastic support,the elastic support model and immobility model for the example of the Crystal Stone Lobby of Juvenile Palace in Shenzhen is done by the ANSYS software of FEM. The method has been proved rationality. Some important conclusions will give advice to structural design.

地基不均匀沉降是导致建筑工程事故的主要原因之一。为了研究地基不均匀沉降对上部结构内力、变形、周期等影响,提出了将地基(或基础)模拟为三维弹性支座的有限元分析方法,将上部结构和地基基础进行整体分析。以深圳市少年宫“水晶石”大厅结构为例,运用有限元软件ANSYS,将三维弹性支承分析法与常用的固定支座法和竖向弹性支承分析法进行了对比分析,验证了三维弹性支承分析法的合理性,从而得出了一些有益的结论,可供设计人员参考。

For generalized model updating problems of jacket-type offshore platforms,a method that updates modal shapes first and updates modal frequencies subsequently for their finite element(FE) model is presented.The updating process is achieved as follows: firstly,the elements that have stiffness discrepancies between the experimental model and the initial FE model are identified by using a damage detection method,then updating the modal shapes for the FE(model) is performed by iterative operations;secondly,regarding...

For generalized model updating problems of jacket-type offshore platforms,a method that updates modal shapes first and updates modal frequencies subsequently for their finite element(FE) model is presented.The updating process is achieved as follows: firstly,the elements that have stiffness discrepancies between the experimental model and the initial FE model are identified by using a damage detection method,then updating the modal shapes for the FE(model) is performed by iterative operations;secondly,regarding the foundation as three-dimensional elastic supports and designing them by an optimization method,updating the modal frequencies for the FE model is implemented.The model updating method is proved to be feasible by employing a model test of an offshore platform based on hammer excitation.And it provides a basis for damage detection and safety evaluation of offshore platforms in long-term service and without measurement of the baseline structure.

针对导管架式海洋平台结构的广义模型修正问题,提出了先修正模态振型后修正模态频率的试验方法。首先利用损伤检测方法识别出试验模型中与初始有限元模型有刚度偏差的杆件单元并采用反复迭代修正的方法进行了有限元模型模态振型的修正;然后将地基模拟为三维弹性支承并对其进行优化设计来实现有限元模型模态频率的修正;通过力锤激励下海洋平台的模型试验验证了此方法的可行性,为长期服役且原型结构未测的海洋平台的损伤检测、安全评估研究提供了基础。
