摘要
为了解充气膜结构研究现状,本文结合近年充气膜结构研究概况,从充气膜结构受力、膜材、找形、载荷、裁剪、结构消防等方面整理相关文献。归纳充气膜结构现有研究特点,如对膜结构进行有限元模拟的数值计算方法逐渐取代物理模型法;对膜材阻燃抑烟性能研究较多,对膜材阻燃稳定性能研究较少;找形常结合启发式算法或摄影测量手段;流固耦合分析柔性膜结构相对复杂;裁剪过程难以确保膜结构形状最佳;建筑膜材防火等级划分较简易,对膜材燃烧特性方面研究较单一。并在分析已有文献的基础上,进一步提出关于充气膜结构的主要应用与研究方向。充气膜应用主要包括储煤棚、体育建筑及沼气贮气装置等;研究方向主要包括非线性与流固耦合效应、储煤棚抗火性能、防火标准规范及气压控制等。
In order to understand the current research status of air-supported membrane structure,this paper combined with the recent research situation of air-supported membrane structure,from the air-supported membrane structure force,membrane material,shape finding,load,cutting,structural fire protection and other aspects of related literature.The existing research characteristics of air-supported membrane structure are summarized.For example,the numerical calculation method of finite element simulation of membrane structure is gradually replacing the physical model method.There are more researches on flame retardant and smoke suppression properties of membrane materials,but less on flame retardant and stability properties of membrane materials.Form finding is often combined with heuristic algorithm or photogrammetry;Fluid structure coupling analysis flexible membrane structure is relatively complex;The cutting process is difficult to ensure the best shape of membrane structure;The fire classification of building membrane is simple,and the study on the combustion characteristics of membrane is simple.On the basis of analyzing the existing literature,the main application and research direction of air-supported membrane structure are further proposed.Air-supported membrane applications mainly include coal storage shed,sports buildings and biogas gas storage devices;Research interests mainly include nonlinear and fluid-structure coupling effect,fire resistance of coal storage shed,fire standard and pressure control,etc.
