高层幕墙防火性能优化与结构改造协同设计研究

Research on Collaborative Design of Fire Performance Optimization and Structural Retrofit for High-Rise Building Curtain Walls

摘要: 随着城市化进程加速，高层建筑幕墙因兼具功能性与美观性被广泛应用，但其空腔结构易引起“烟囱效应”，导致火灾快速蔓延，其火灾安全隐患日益凸显。本文结合国内外规范差异，通过材料性能与层间防火设计对比，提出防火材料选型标准与分隔方式优化方案，为高层幕墙安全设计与改造提供科学依据。

Abstract: With the acceleration of urbanization, high-rise building curtain walls have been widely adopted for their functional and aesthetic advantages. However, their cavity structures are prone to the “chimney effect”, leading to rapid fire spread and increasingly prominent fire safety risks. This study compares material performance and inter-floor fire compartmentation designs based on discrepancies between domestic and international codes. It proposes fire-resistant material selection criteria and optimization schemes for fire compartmentation methods, providing scientific guidance for the safety-oriented design and retrofitting of high-rise curtain walls.
