Innovative structural fastening system for building envelope

建筑结构通常由混凝土、钢、砖石或木材或它们的组合制成。在这些结构中，许多部件使用紧固系统相互连接在一起。建筑行业对更灵活和可靠的连接方法的需求，以及提高建筑结构性能的努力，特别关注了紧固系统的设计、安装和性能。紧固件的设计要求是通过张力、剪切或张力和剪切的组合将结构荷载传递给支撑结构元件；或与安全相关的附件和结构元件。建筑规范中规定的安全等级适用于使用条件，而不是短期处理和施工条件。考虑到目前建筑围护结构包层紧固系统的有限和通用指南，有必要进行一项

Building structures are normally made of concrete, steel, masonry or wood or combination thereof. In these structures, many parts are interconnected together using fastening systems. The demands of the building industry for more flexible and dependable connection methods and efforts to improve the performance of building structures have focused particular attention on the design, installation and performance of fastening systems. The design requirements for fasteners are to transmit structural loads by means of tension, shear, or a combination of tension and shear to the supporting structural elements; or safety-related attachments and structural elements. Safety levels that are specified in building codes are intended for in-service conditions, rather than for short-term handling and construction conditions. Considering limited and general guidelines currently available for the fastening system of building envelope cladding, there is a need to carry out a
