【摘要】：进入二十一世纪以来,我国经济飞速发展,城市化进程不断推进,汽车拥有量急剧增加,停车难问题日益严重,这已成为影响我国社会以及经济发展的一个重要因素。立体车库作为一种新型的停车方式,能够较好地解决我国城市停车难问题。目前,世界各国的立体车库以钢结构和现浇混凝土结构为主,钢结构建筑的特点是重量比较轻,强度较高,施工安装方便。然而,钢材的耐火耐腐蚀性能差,导热系数大,特别在火灾高温下,构件的强度下降得很快,很容易倒塌破坏,可能造成周围建筑倒塌,甚至于人员伤亡。现浇混凝土结构具有造价较低,防火性能与抗腐蚀性能较好等特点,但是施工过程中存在需要提供较大的施工场地、较多的施工人员与施工机械、施工工期长和对周围的影响较大等缺点。为了满足立体车库施工方便快捷,同时弥补钢结构防火性能与抗腐蚀性能较差的要求。在这种严峻形势下,装配式混凝土立体车库的优势也就逐渐显现出来。本文以钢筋混凝土立体车库为研究对象,在进行结构整体分析基础上,对钢筋混凝土立体车库进行了结构整体分析对比,并对构件节点进行了分类设计,初步形成结构设计施工图纸,为装配式混凝土立体车库的进一步研究应用提供参考。具体完成的工作如下：(1)介绍了立体车库的各种类型、特点以及设计时需要注意的事项,最后选择了电梯升降式立体车库作为研究对象,并对这种立体车库的各项参数进行了确定：如立体车库结构的组成,平面参数,层高以及荷载的确定。(2)按照混凝土剪力墙结构的设计原理,对五栋不同层数的单筒立体车库以及六栋不同层高立体组合型车库进行了整体分析对比,并选择出典型的立体车库结构进行了完整的计算,从侧移和配筋量两个角度分析了其结构的合理性及经济性,提出了适合剪力墙结构立体车库的高宽比。(3)在结构计算分析过程基础上,对单筒与双筒装配式立体车库结构进行竖向与横向的构件分解,并根据现行设计标准和规范,进行了节点设计,以确保节点和整体结构的可靠性。
[Abstract]:Since the 21 century, China's economy has developed rapidly, the urbanization process has been advancing, the number of cars has increased sharply, and the problem of parking is becoming more and more serious, which has become an important factor affecting the social and economic development of our country. As a new type of parking mode, the stereoscopic garage can solve the difficult problem of parking in our country. At present, steel structure and cast-in-place concrete structure are the main types of solid garages in the world. The characteristics of steel structure buildings are light weight, high strength and convenient installation. However, the refractory corrosion resistance of steel is poor, and the thermal conductivity is large. Especially under the high temperature, the strength of the components decreases rapidly, and it is easy to collapse and destroy, which may lead to the collapse of the surrounding buildings and even casualties. The cast-in-place concrete structure has the characteristics of low cost, good fire resistance and corrosion resistance, but in the process of construction, it is necessary to provide a large construction site, more construction personnel and construction machinery, The disadvantages of long construction period and great influence on the surrounding area. In order to meet the convenience of three-dimensional garage construction and make up for the poor fire resistance and corrosion resistance of steel structure. In this grim situation, the advantages of the prefabricated concrete stereoscopic garage will gradually appear. This paper takes the reinforced concrete stereoscopic garage as the research object, on the basis of the whole structure analysis, carries on the structural whole analysis contrast to the reinforced concrete stereoscopic garage, and carries on the classification design to the member node. The structural design and construction drawings are formed preliminarily, which provides a reference for the further research and application of the prefabricated concrete stereoscopic garage. The work accomplished is as follows: (1) the various types, characteristics and matters needing attention in the design of the three-dimensional garage are introduced. Finally, the elevator lift type three-dimensional garage is selected as the research object. The parameters of the three-dimensional garage are determined, such as the composition of the structure, the plane parameters, the height of the floor and the load. (2) according to the design principle of the concrete shear wall structure, The whole analysis and comparison of five single cylinder garages with different layers and six different storeys high stereoscopic combined garages are carried out, and the typical stereoscopic garage structures are selected for complete calculation. This paper analyzes the rationality and economy of the structure from two angles of lateral displacement and reinforcement quantity, and puts forward the ratio of height to width suitable for the three-dimensional garage of shear wall structure. (3) on the basis of the calculation and analysis of the structure, The structure of single-cylinder and double-cylinder assembled stereoscopic garage is decomposed vertically and horizontally, and according to the current design standards and codes, the joint design is carried out to ensure the reliability of the joint and the whole structure.
