【摘要】 单层索网体系是点支式柔性支承玻璃幕墙结构中的一种新型体系 ,以其僵筑结构简捷、轻盈美观、通透性好等优点深受许多建筑师的青睐 ,应用前景广泛。由于采用了柔性索杆 ,它的设计方法不同于其他一般的幕墙结构 ,除满足结构强度、刚度、变形要求外 ,还要考虑预应力和几何非线性问题。结合单层索网柔性支承体系在国内外幕墙工程中的应用 ,阐述了该体系的受力特点、研究现状和存在的问题 ,并对其设计分析和施工技术中的主要问题进行了探讨。更多还原

【Abstract】 The supporting system for single-layer cable net is a new style of flexible supporting systems of point-supported glass curtain wall,which has been accepted and favored by architects in virtue of light-weight,elegant appearance and excellent transparency etc,and it has wide applications.However,its designing is different from other common structures due to the induction of cables and rods,and its pretension and geometric nonlinear properties must be considered,in addition to satisfying requirements of structural strength,stiffness and deformation.The characteristics of this kind of supporting systems under forces,research status and problems emerging at present are reviewed,combined with its engineering applications both at home and abroad.Meanwhile,some problems existing in its design and during construction are also discussed herein.更多还原
