摘要
折板形斜拉空间网格结构是预应力技术应用到空间结构而形成的一种形式新颖的预应力大跨度空间结构体系,以其良好的受力性能和新颖的建筑造型适应现代建筑发展的要求,具有广阔的应用前景。本文以滨海国际会展中心二期工程展厅结构为工程背景,针对折板形斜拉空间网格结构设计施工关键技术,将主要开展以下研究。
简述斜拉空间网格结构的形成及应用发展,详细介绍本课题选题背景,提出本文主要研究工作内容。
结合斜拉空间网格结构选型要求,分析原结构体系的缺点,提出优化后的结构体系。并进一步对比分析优化前后两种结构单元的受力性能,确定优化后结构体系的合理性。
应用通用有限元软件,在给定的斜拉索预应力作用下,分析整体结构在各种荷载工况作用下的安全性能、空间网格结构杆件的应力分布、变形性能以及整体结构的自振特性。
对结构中的复杂节点开展理论分析和试验研究,对比分析理论结果和试验结果,验证有限元模型和试验方法的合理性,并对节点的受力性能进行评价,同时为复杂节点设计提供参考。
分析斜拉索预应力值对整体结构静力性能和自振频率的影响,分别以整体结构初始状态和工作状态的最大位移为优化目标进行拉索预应力值优化,提出拉索最优预应力建议值。
结合传统预应力张拉方法,提出本工程的预应力张拉方案。根据具体的施工工艺,分析结构在张拉过程中的受力状态,研究拉索张拉过程对结构性能的影响,确保张拉施工时结构的安全性。
结合工程特点,采用弧形轨道累积滑移施工方法。对施工方法、安装流程及滑道体系等施工要点及施工过程中的关键技术展开研究。

The initiation and application of prestressed cable-stayed space truss structure is described. Based on the introduction of selected topic background, the main research work of the task in this thesis is pointed out.
According to the requirement of selecting type, the disadvantages of the original structure system are pointed out. Further optimal design is put into effect. In the end the dissertation compares the performance of the optimized structure unite with the original one in order to reach the optimization effect.
Using the finite element analysis software ANSYS, analysis of whole structure performance is completed under the given cable-tension prestressing force. The following characteristics are analyzed: The safe capability of the whole structure under every load case, stress distribution on the member bar, deformation analysis of whole structure, as well as the structural system’s dynamic characteristic.
Theoretical analysis and experimental study on the complex node are carried out, combining with the experimental and finite element analysis result, the rationality of the finite element method and experimental method is validated. Endure performance and bearing capacity of the joint are apprised and complex nodes design is offered for reference.
Based on the influence analysis of different prestress on static performance and natural vibration frequency of whole structure, optimum design of prestress value is given to reduce the maximum displacement under initial state and work state, and optimum results are obtained.
Prestress tension technology and scheme are determined by suming up traditional cable tension methods. The general analysis software—ANSYS is used to analyze the tension process of cab according to specific construction process. The forced state in the course of tension process is analyzed, so the influence of prestress tension on structure performance and the structure safety can be arrived.
Combinating with engineering characteristics, accumulative sliding construction on an arc track is adopted. The construction methods, installation procedure, slide rail system and the key technology are discussed.
