     张拉膜结构工程是建筑结构中最新发展起来的一种形式,自从1970年代以来, 膜结构在国外已逐渐应用于体育建筑、商场、展览中心、交通服务设
施等大跨度建筑中。
    Tension membrane structure engineering is the latest development of the building structure of a form, since the 1970s, the membrane 
structure in foreign countries has been gradually applied to sports buildings, shopping malls, exhibition centers, transportation 
services and other large-span buildings.

      张拉膜结构单元的标志明确。因而近来年,这类建筑越来越多采用膜结构。建筑膜材料的使用寿命为25年以上。在使用期间,在雪或风荷载作用下
均能保持材料的力学形态稳定不变。建成於1973年的美国加州La Verne大学的学生活动中心是已有23年历史的张拉膜结构建筑.跟踪测试与材料的加载与
加速气候变化的试验,证明它的膜材料的力学性能与化学稳定性指标下降了20%至30%,但仍可正常使用。膜的表层光滑,具有弹性,大气中的灰尘、化学
物质的微粒极难附著与渗透,经雨水的冲刷建筑膜可恢复其原有的清洁面层与透光性。
      The tensile membrane structural unit is clearly marked. Thus in recent years, more and more of these buildings using membrane 
structure. The life of the building film material is more than 25 years. During the use, under the action of snow or wind load, the 
mechanical form of the material can be kept stable. Built in 1973, the University of California La Verne student activity center is a 
23-year history of tensioned membrane structure. Tracking test and material loading and accelerated climate change test, proved that 
its mechanical properties of the membrane material and chemical stability index decreased by 20% to 30%, but can still be used 
normally. The surface of the film is smooth and elastic, the dust in the atmosphere, the particles of the chemical substance are 
extremely difficult to attach and penetrate, and the washed film of the rain can restore its original cleaning surface and light 
transmission.
      张拉整体结构工程 (Tensegrity)是由一组连续的拉杆和连续的或不连续的压杆组合而成的自应力、自支撑的网状杆系结构,其中「不连续的压杆
」的含义是压杆的端部互不接触,即一个节点上只连接一个压杆。 Tensegrity是美国建筑师 R.B.Fuller首先提出的一种结构思想,他认为宇宙的运行就
是按照张拉整体的原理进行的,即万有引力是一个平衡的张力网,各个星球是这个网中的一个个独立的孤立点。这种结构体系中的索网就相当於宇宙中的
万有引力,独立的受压杆件相当於宇宙中的星球。
      Tensegrity is a self-sustaining, self-supporting, mesh-like structure consisting of a continuous set of rods and continuous or 
discontinuous compression bars, with the meaning of "discontinuous compression bars" Is the end of the bar does not touch each other, 
that is, a node is only connected to a pressure bar. Tensegrity is the American architect RBFuller first proposed a structural idea, he 
believes that the operation of the universe is carried out in accordance with the principle of tension as a whole, that gravitation is 
a balanced tension network, the planet is the network of a separate Isolated point. The cable system in this structure is equivalent to 
the gravitational force in the universe, and the independent compression bar is equivalent to the planet in the universe.

简述/Brief
    只有正确表达结构逻辑的建筑才有强大的说服力与表现力”这句话揭示了张拉膜结构的精髓。对于张拉膜结构,任何附加的支撑和修饰都是多余的,
其结构本身就是造型;换句话说,不符合结构的造型是不可能的,因为那样的薄膜不是飘动的就是缺乏稳定性的。张拉膜结构的美就在于其“力”与“形
”的完美结合。 张拉膜结构的基本组成单元通常有:膜材、索与支承结构(桅杆、拱或其他刚性构件)。
    The tensile membrane structural unit is clearly marked. Thus in recent years, more and more of these buildings using membrane 
structure. The life of the building film material is more than 25 years. During the use, under the action of snow or wind load, the 
mechanical form of the material can be kept stable. Built in 1973, the University of California La Verne student activity center is a 
23-year history of tensioned membrane structure. Tracking test and material loading and accelerated climate change test, proved that 
its mechanical properties of the membrane material and chemical stability index decreased by 20% to 30%, but can still be used 
normally. The surface of the film is smooth and elastic, the dust in the atmosphere, the particles of the chemical substance are 
extremely difficult to attach and penetrate, and the washed film of the rain can restore its original cleaning surface and light 
transmission.
     张拉膜材材料一种新兴的建筑材料,已被公认为是继砖、石、混凝土、钢和木材之后的“第六种建筑材料”。膜材本身受压不大,抗弯也不是很好,
所以要使膜结构正常工作就必须引入适当的预张力。此外,要保证膜结构正常工作的另一个重要条件就是要形成互反曲面。传统结构为了减小结构的变形
就必须增加结构的抗力;而膜结构是通过改变形状来分散荷载,从而获得最小内力增长的。当膜结构在平衡位置附近出现变形时,可产生两种回复力:一
个是由几何变形引起的;另一个是由材料应变引起的。
  A new building material that has been recognized as a "sixth building material" after brick, stone, concrete, steel and wood. The 
membrane itself is not subject to pressure, bending is not very good, so the membrane structure to work properly to introduce the 
appropriate pre-tension.
In addition, to ensure that the membrane structure of the normal work of another important condition is to form a reciprocal surface. 
The traditional structure in order to reduce the deformation of the structure must increase the resistance of the structure; and 
membrane structure is to change the shape to disperse the load, resulting in the minimum internal force growth. When the membrane 
structure in the vicinity of the equilibrium position deformation, can produce two kinds of recovery force: one is caused by geometric 
deformation; the other is caused by the material strain.
    通常几何刚度要比弹性刚度大得多,所以要使每一个膜片具有良好的刚度,就应尽量形成负高斯曲面,即沿对角方向分别形成“高点”和“低点”。
“高点”通常是由桅杆来提供的,也许是由于这个原因,有些文献上也把张拉膜结构叫做悬挂膜结构(suspension membrane)。 
    Usually the geometric stiffness is much larger than the elastic stiffness, so to make each diaphragm has a good stiffness, it 
should try to form negative Gaussian surface, that is, along the diagonal direction were formed "high" and "low". "High point" is 
usually provided by the mast, perhaps for this reason, some of the literature also pull the membrane structure called suspension 
membrane structure (suspension membrane).
   索作为膜材的弹性边界,将膜材划分为一系列膜片,从而减小了膜材的自由支承长度,使薄膜表面更易形成较大的曲率。有文献指出,膜材的自由支承
长度不宜超过15米,且单片膜的覆盖面积不宜大于500平米。此外,索的另一个重要作用就是对桅杆等支承结构提供附加支撑,从而保证不会因膜材的破损
而造成支承结构的倒塌。
   As the elastic boundary of the membrane, the membrane is divided into a series of diaphragms, thus reducing the free length of the 
membrane, so that the film surface is more likely to form a larger curvature. It is pointed out that the length of the free support of 
the membrane should not exceed 15 meters, and the coverage area of ??the single film should not be greater than 500 square meters. In 
addition, the cable another important role is to support the structure of the mast and other support to ensure that the film will not 
be damaged due to damage caused by the collapse of the structure.
