【摘要】：近年来,随着我国经济建设的蓬勃发展、人民生活水平的不断提高,大跨工业厂房、侯机大厅、会展中心、剧院、体育场馆等大型工业、公共建筑不断涌现,大跨空间结构得到了前所未有的飞速发展,并且获得了广泛地应用。 索膜结构体系是一种新型的建筑结构形式,由于其大部分构件均是承受拉力,因此具有受力合理性、高效性以及造型新颖独特等优点。近年来,这种结构形式越来越受到工程界的关注,无论是在建筑小品还是大跨结构中都会展现出巨大的应用前景。 本文结合宝安体育场屋盖的施工监测工作,对其进行深入研究,具体工作内容如下: (1)在广泛查阅相关文献的基础上,回顾膜结构建筑的发展历程,介绍索膜结构的概念、分类及特点,对国内外膜结构研究状况和进展进行了介绍。 (2)应用Strand 7软件对屋盖索结构的安装过程进行计算机仿真分析,分析不同施工工况对结构的影响,根据仿真结果指导施工工序。 (3)详细介绍了该屋盖索结构的整个施工过程及施工监测过程,并将实测应力、位移监测数据与模拟数据进行列表分析,保证施工的安全进行。 (4)介绍了一种基于悬链线索形理论的求解拉索高精度静力状态的无迭代方法,并将其应用于宝安体育场径向索索力的求解,对分析结果进行列表比对,验证了该方法求得的索力值与理论值偏差较小,对施工具有一定指导意义。 最后,总结证明了张拉径向索的施工方法、计算机仿真技术的应用以及现场应力、位移的监测有效地指导整个施工过程,保证该工程安全、顺利完成。
[Abstract]:In recent years, with the vigorous development of our country's economic construction and the continuous improvement of the people's living standards, large industrial buildings, such as large industrial buildings, concierge halls, convention and exhibition centers, theatres, stadiums and stadiums, have sprung up, and public buildings have continued to emerge. Long-span space structure has been developed at an unprecedented speed and widely used. Cable-membrane structure system is a new type of building structure, because most of its members are subjected to tensile force, so it has the advantages of force rationality, high efficiency and novel and unique shape. In recent years, more and more attention has been paid to this form of structure, both in architectural sketches and long-span structures will show a huge application prospects. Combined with the construction monitoring work of Baoan Stadium, this paper makes a deep study on it. The specific contents are as follows: (1) based on the extensive reference to relevant literature, the development of membrane structure building is reviewed. This paper introduces the concept, classification and characteristics of cable-membrane structure, and introduces the research status and progress of membrane structure at home and abroad. (2) the installation process of roof cable structure is simulated and analyzed by Strand 7 software, and the influence of different construction conditions on the structure is analyzed. According to the simulation results, the construction procedure is guided. (3) the whole construction process and construction monitoring process of the roof cable structure are introduced in detail, and the measured stress, displacement monitoring data and simulation data are analyzed in order to ensure the safety of construction. (4) an iterative method based on catenary cue-shape theory is introduced to solve the static state of cable with high precision, and it is applied to the solution of radial cable force in Baoan Stadium. It is verified that the deviation between the cable force obtained by the method and the theoretical value is small, which is of certain guiding significance to the construction. Finally, it is proved that the construction method of tension radial cable, the application of computer simulation technology and the monitoring of field stress and displacement can effectively guide the whole construction process and ensure the safety and smooth completion of the project.
