钢结构建筑的防火摘要: 随着钢结构建筑的快速发展,作为建筑的一个分支,现如今与砌体结构、钢筋混凝土结构一样是建筑的重要组成部分。钢结构具有强度高、自重轻、抗震性好、施工污染少、可循环再生、使用率高等一系列优点。可工业化生产,在工厂中预制后到现场整体装配,具备其他结构无法比拟的优点。然而在这些优点的背后, 也伴随着钢结构建筑致命弱点—耐火性能差, 高温下虽不燃烧, 但极易发生变形和破坏。本文从钢材特点出发探讨了钢结构防火的研究与房展, 以及钢结构防火设计的一些措施与注意事项。关键词: 钢结构、钢材、耐火、防火设计、 Abstract : With the rapid development of steel structure buildings, a branch ofa building, nowadays and masonry structure of reinforced concrete structure, as is the ponent of the building. Steel structure has high strength, light weight, good, construction pollution extent, circulating regeneration, less a series of advantages of higher utilization rate. But industrialized production, prefabricated in factories to the whole assembly after the other structures, have the parable virtues. However, in these advantages, is panied by steel structure behind fatal weakness - architectural fireproof performance is poor, though not burning under high temperature, but easily happened deformation and failure. This paper discussed from steel characteristics of the steel structure fire-proofing research and exhibitions, and steel structure fire-protection design and precautions of some of the measures. Key words: steel structure rolled steel fire-resistant fire protection design 正文引言:2010 年11月15日14时,上海余姚路胶州路一栋高层公寓起火。据附近居民介绍,公寓内住着不少退休教师,起火点位于 10-12 层之间,整栋楼都被大火包围着,楼内还有不少居民没有撤离。大火导致 58人遇难,另有 70余人正在接受治疗。事故原因已初步查明,是由无证电焊工违章操作引起的,施工作业现场管理混乱,
