201 4中華民國營建工程學會第十 二屆營 建 產業永續發展研討會 鋼構造廠房坍塌事故原因案例探討 李景亮 李文修 中國科技大學講師 中國科技大學建築研究所研究生 摘要 鋼結構具有高強度、高韌性及耐震性的優點，在考慮省能與減少產生營建廢棄 物等因素下，一般廠房建築物結構多採用鋼構造興建施工 。近年來由於營建業景 氣的低迷與市場惡性之競爭， 以及鋼構廠商削價競爭與工程成本面臨嚴重虧損等 壓力下，於是鋼構施工品質難以有效管理及監督，特別是銲接施工品質的不良， 往往容易造成工程災害進而危害建築物安全 。 本文以案例探討方式，針對鋼構柱樑接頭銲接品質缺失因子關係，藉由設計 及施工詳細檢討進行有效評估，進而作為後續工程人員對鋼構廠評估銲接施工品 質及改善計畫的依據，以協助鋼構柱樑接頭銲接品管人員，執行鋼構工程品質管 制時，能克服鋼構銲接施工品質所面臨的問題，希望藉此鋼構接施工管理模式， 能大幅降低銲接施工缺陷現象的發生，以確保整體鋼構工程銲接施工品質。 關鍵詞 ：鋼構柱樑接頭、銲接缺陷、銲接施工管理 Case study on the reasons of the steel structure factory collapse Abstract Steel structure has high strength 、high toughness and earthquake- resistance advantage and can be more energy-saving and reduce the waste in construction.Nowadays we adopt steel structure to build the plants. Recently du to the depression in the construction industry and “cost down” competition, the supplier of steel structure confront the “cost down” competition and deficit of construction cost. In this situation the construction quality is hardly be controlled under effect management especially so as to the unqualified of steel welded that conduct construction damage and the building safety threatened In this paper, discuss with case example, the relation between the lack of steel columns and beams joint welding quality. Thru design and intensive construction make effective estimations. In accordance with these make improving plan for later member to assist the QC member then to execution steel construction quality control and the overcome the welding quality problem. Thru this steel welded construction management modal reduce the welding deficit to ensure overall steel weld
