薄膜结构是一种柔韧的薄面结构,它主要是通过表面张力来承受荷载。肥皂泡是用来说明什么是薄膜结构及其具有何种特征的恰当的例子。跟肥皂泡的柔性极其相似,薄膜结构的表面形状会因荷载而异。薄膜结构对风荷载的空气动力影响十分敏感,风载能引起薄膜结构发生振颤。因此,用子建筑上的薄膜结构大多需要用某些稳定方法使它们在各种荷载作用下能够保持其基本的形状。稳定薄膜结构有几种基本方法。例如,在薄膜内部用刚性的框架支撑就是其中的一种。如何通过对薄膜面预加应力来使其达到稳定状态,是本文所特别要加以研究的。施加外力绷紧薄膜或者对具有封闭容积 The thin-film structure is a flexible, thin-walled structure that is primarily loaded with surface tension. Soap bubbles are a good example of what a thin film structure and what features it has. Very similar to the flexibility of soap bubbles, the surface shape of the film structure will vary depending on the load. The membrane structure is very sensitive to the aerodynamic effects of wind loads, and the wind load can cause vibrations in the thin film structure. Therefore, the thin-film structures on substructures mostly need to be stabilized by a certain method so that they can maintain their basic shape under various loads. There are several basic methods for stabilizing the film structure. For example, supporting a rigid frame inside the film is one of them. How to achieve a steady state by pre-stressing the film surface is the subject of this article. Apply external force to tighten the film or have a closed volume
