國內低樓層鋼結構建築設計與施工問題探討

Abstract

本文旨在探討921集集大地震之後國內低樓層鋼骨建築在設計與施工等方面的問題。一般民眾在看到921大地震中嚴重倒塌的鋼筋混凝土建築之後，由於心生恐懼而有轉而求向鋼骨建築的趨勢，以祈求一個較為安全的庇護場所。然而，根據本研究的調查發現，由於國內五樓以下的建築物在設計時並不需要經由專業技師簽證，再加上民間小型施工廠商與工人對鋼結構的專業知識普遍不足，以及監造未能落實等嚴重缺失，已經使得國內低樓層鋼骨建築的耐震能力大打折扣，甚至可能成為下一次大地震中倒塌的建築物，這種現象實在令人憂心。因此，政府相關單位如何能夠速謀因應對策，實是當務之急。

Presented herein are some discovered problems related to the design, construction and inspection of the low rise steel buildings constructed in Taiwan after the 921 JiJI earthquake in 1999. The massive collapse of reinforced concrete buildings during the 921 earthquake has turned people’s focus on steel structural buildings. However, the results of this investigation reveal that many of the low rise steel buildings constructed during the past two years contain serious defects due to improper design, construction and inspection. It is the writer’s concern that these poor quality steel buildings may become the next target of a future major earthquake.
