中小學校舍耐震評估與補強工作之芻議

A PROPOSAL FOR SEISMIC ASSESSMENT AND RETROFIT OF ELEMENTARY SCHOOL BUILDINGS

歷年來之地震災損報告均指出台灣之中小學校舍為破壞最嚴重的一群建築物，因此儘速透過補強的手段來提昇校舍的耐震能力，實為當務之急。然而台灣的中小學約有3,360 所，而校舍建築高達三萬多棟。若無經濟有效之法，如此龐大之數量極易耗盡財源，而難以成功。本文即針對此一問題，提出解決之芻議。首先對現有之校舍耐震能力評估方法作探討，再據以提出將校舍耐震評估與補強工作分為三級之建議。再整合學者專家之意見，製訂中小學耐震補強作業之參考流程。最後並提出校舍結構耐震資訊網之輔助機制芻議。期以經濟有效之手段，按照輕重緩急之順序，全面地逐年提昇校舍結構之耐震能力，以保障台灣師生之安全。

The recent reconnaissance reports revealed that the elementary school buildings are particularly vulnerable structures in Taiwan. So there is an urgent need to enhance the seismic capacities of school buildings through retrofitting. However, there are 3,360 elementary schools in Taiwan, and the building number can reach as high as thirty thousands. Without a careful planning, this huge volume of building can easily consume the budgets. This paper provides a proposal to solve the problems related to school buildings. Firstly, the available methods to assess the seismic capacities of school buildings were surveyed and introduced. Based on those findings, the procedure for seismic assessment and retrofit of school buildings was suggested to be divided into three steps. Furthermore, a reference procedure for assessment and retrofit was recommended with inputs from invited specialists. Finally, a network on the seismic capacity of school buildings was proposed as an auxiliary mechanism. The objective of this paper is to propose an economical procedure which can enhance the seismic capacities of school buildings. Hopefully, the safety of the school buildings in Taiwan is ensured.
