In this research, a cable-type wall system that could replace the conventional aluminum curtain wall system for reinforced concrete high-rise buildings is proposed. The cable-type wall system is a newly developed system, which could be used as an existing exterior skin system, and can effectively support the wind load acting on the exterior of the high-rise buildings by the pre-induced initial tension force to the cable supporting the glass. The main advantages of the cable-type wall system are that the expense of construction could be reduced due to the simplicity of the construction. The experiment of structural analysis and air/water tightness was performed to evaluate its feasibility of industrialization. The structural performance of the cable-type wall system was evaluated through the structural analysis and the full-scale experiment to predict the initial pre-tension force and the design load displacement of the vertical one-way cable-type wall system that can be used for a typical floor of the high-rise building. The initial pre-tension force and structural behavior of the cable were analyzed by using the structural design program MIDAS-Gen. The maximum deformation value in the structural test was found to satisfy the AAMA condition, which is equal to the size of the facade skin system. The air/water tightness test was conducted to verify the performance. Test results show that the cable-type wall system satisfies the air/water tightness performance standards ASTM E283, E331 and AAMA 501.1-05 which are the most basic standards that the facade system must provide. As a result of this study, it is expected that the proposed cable-type wall system could be used for facade system, not only the structural performance but also air/water tightness performance are secured.

钢筋混凝土高层建筑索式幕墙系统抗风性能评价

在这项研究中,提出了一种可以替代钢筋混凝土高层建筑传统铝幕墙系统的索式墙系统。索式墙体系统是一种新开发的系统,可作为现有的外墙系统,通过对高层建筑的预诱导初拉力,有效支撑作用在高层建筑外部的风荷载。支撑玻璃的电缆。索式墙体系统的主要优点是由于施工简单,可以减少施工费用。进行结构分析和气密性/水密性实验,评价其产业化可行性。索式墙系统的结构性能通过结构分析和全尺寸试验进行评估,以预测可使用的垂直单向索式墙系统的初始预拉力和设计荷载位移对于高层建筑的典型楼层。使用结构设计程序 MIDAS-Gen 分析了电缆的初始预紧力和结构行为。发现结构试验中的最大变形值满足 AAMA 条件,即等于立面蒙皮系统的尺寸。进行气密性/水密性测试以验证性能。测试结果表明,索式墙体系统满足气密/水密性能标准ASTM E283、E331和AAMA 501。1-05 这是幕墙系统必须提供的最基本的标准。作为这项研究的结果,预计所提出的索式墙系统可用于外墙系统,不仅保证结构性能,而且保证气密/水密性能。
