校舍補強工程經費之影響因素分析

我國中小學校舍補強計畫從民國九十八年累積至今，已經普查了三萬多棟校舍建物，其中累積的補強案例資料具有相當大的分析價值。三萬多棟校舍所累積的評估資料及工程報告複雜且龐大，透過耐震補強資料庫得以妥善記錄補強各階段之資料。本研究依據校舍耐震補強資料庫，分析單價與地區、補強工法及耐震容量提升程度之關係，期能作為未來估算耐震補強工程經費之參考依據。本研究針對校舍補強資料庫資料，在分析上分別藉由地區、工法以及耐震容量提升程度進行補強工程經費影響因素分析。影響補強工程經費的因素眾多，本文僅透過資料庫的資料探討單價與上述三種因素之間的關係。在校舍補強工法使用次數統計中，翼牆、擴柱及剪力牆為最常使用的補強方式，相較之下其它補強方式則為少數。本研究主要以翼牆、擴柱及剪力牆三種補強方式進行初步分析。

The cases in the school building seismic retrofit have significant values for data analysis. The school building seismic retrofit data has been accumulated since 2009. More than 30,000 school building structures have been generally surveyed. More than 17,000 of them were preliminarily evaluated, and more than 10,000 of them which had significant risk of damage from earthquakes were evaluated. More than 6,000 of them have been retrofitted. As long as the analysis results are properly utilized, we will have more comprehensive understanding of construction cost, as well as potential for improving the administrative processes. Based on the aforementioned database, this research analyzed the factors affecting the construction cost based on school locations, retrofit methods, and seismic capacity increment. In the statistics of the use of school building retrofit methods, it is found that wing walls, RC jacketing, and shear walls are the most commonly used retrofit methods. There are many factors that affect the project cost. This article studied the relationship between the retrofit cost and the above three factors through the data analysis.
