The wrinkling on the membrane surface of the membrane structure car shed refers to the deformation of the membrane material outside the surface or outside the surface under uniaxial tensile stress. Generally speaking, it can be divided into two types: one is the relaxation of the membrane material caused by the disappearance of surface tension in one direction, which is called structural wrinkling; the other is caused by defects in the membrane production process, improper thermal bonding, or improper packaging folding, which is called material folding.

褶皱对膜结构车棚的结构和性能的影响不可忽视，这不仅体现在视觉效果上，褶皱的出现会导致膜表面预张力的重新分布，使得膜表面某些区域的应力低于设计值，而其他区域的应力高于设计值。

The impact of wrinkles on the structure and performance of membrane structure car sheds cannot be ignored, which is not only reflected in the visual effect. The appearance of wrinkles can lead to the redistribution of pre tension on the membrane surface, causing stress in some areas of the membrane surface to be lower than the design value, while stress in other areas is higher than the design value.

当膜应力高于设计值时，将导致更大的应变和突变，甚膜的局部撕裂，皱纹也会影响膜结构的美观和排水性能，在膜结构的施工中，在正常的长期荷载组合下，应尽量避免褶皱。

When the membrane stress is higher than the design value, it will lead to greater strain and sudden changes, and even local tearing and wrinkles of the membrane can affect the aesthetics and drainage performance of the membrane structure. In the construction of membrane structures, wrinkles should be avoided as much as possible under normal long-term load combinations.

材料褶皱的情况很少出现，一般是由于膜布生产厂家所出现的问题，后天很难解决。在实际生产中，膜结构的加工和安装是影响膜结构褶皱的主要原因，施工人员应重视这个方面，加强具体措施，减少膜结构的膜褶皱，使膜结构美观。

The occurrence of material wrinkles is rare, usually due to problems encountered by membrane fabric manufacturers, which are difficult to solve the day after tomorrow. In actual production, the processing and installation of membrane structures are the main reasons that affect membrane structure wrinkles. Construction personnel should pay attention to this aspect, strengthen specific measures, reduce membrane wrinkles in membrane structures, and make them beautiful.
