摘要

介绍了一种改进的ETFE缓冲膜结构载荷效应分析方法。与现有方法相比，改进的方法同时考虑了空气膜相互作用和索膜摩擦接触，并开发了一种高效的自适应载荷迭代算法（ALIA）。通常，该算法只需3-5次迭代即可准确计算ETFE缓冲垫的负载效应。为了验证ALIA的合理性，设计并进行了一系列索增强ETFE模型试验，考察了不同荷载条件下的结构响应。数值模拟与实验数据的对比分析证实了自适应载荷迭代算法的准确性和适用性，为缓冲膜结构的设计与分析提供了一种有效的计算方法。

Improvement of analysis method for cable-reinforced ETFE cushion structure

This study introduces an improved load effect analysis method for ETFE cushion membrane structures. Compared to existing methods, this improved approach incorporates both air-membrane interaction and cable-membrane frictional contact, and it has developed an efficient Adaptive Load Iteration Algorithm (ALIA). Typically, the algorithm requires only 3–5 iterations to accurately calculate the load effects on ETFE cushions. To validate the rationality of the ALIA, a series of tests with cable-reinforced ETFE models were designed and conducted to examine the structural responses under various load conditions. Comparative analysis between the numerical simulations and experimental data confirms the accuracy and applicability of the Adaptive Load Iteration Algorithm, providing an effective computational method for the design and analysis of cushion membrane structures.

期刊介绍： Engineering Structures provides a forum for a broad blend of scientific and technical papers to reflect the evolving needs of the structural engineering and structural mechanics communities. Particularly welcome are contributions dealing with applications of structural engineering and mechanics principles in all areas of technology. The journal aspires to a broad and integrated coverage of the effects of dynamic loadings and of the modelling techniques whereby the structural response to these loadings may be computed. The scope of Engineering Structures encompasses, but is not restricted to, the following areas: infrastructure engineering; earthquake engineering; structure-fluid-soil interaction; wind engineering; fire engineering; blast engineering; structural reliability/stability; life assessment/integrity; structural health monitoring; multi-hazard engineering; structural dynamics; optimization; expert systems; experimental modelling; performance-based design; multiscale analysis; value engineering. Topics of interest include: tall buildings; innovative structures; environmentally responsive structures; bridges; stadiums; commercial and public buildings; transmission towers; television and telecommunication masts; foldable structures; cooling towers; plates and shells; suspension structures; protective structures; smart structures; nuclear reactors; dams; pressure vessels; pipelines; tunnels. Engineering Structures also publishes review articles, short communications and discussions, book reviews, and a diary on international events related to any aspect of structural engineering.
