摘要

在經歷發生於民國八十八年的921集集大地震的慘痛經歷後，我國引進在國際上新一代耐震研究理念之性能設計法，並進行耐震性能相關研究；而此理念不僅運用於新建建築物之設計上，也影響耐震補強之評估與設計。中小學校舍為學生平時上課聚集之處所，同時當遭遇重大災難時經常作為該地區人民緊急避難之場所，故中小學校舍建築物之耐震能力極為重要；但因國內有頗多的中小學校舍係為早年興建，其使用之耐震設計規範不如現今完整，故許多的中小學校舍建築物有耐震能力之疑慮。而隨著耐震相關研究之發展，校舍建築物可以依據耐震能力評估判斷是否須進行補強，並透過耐震補強的方式以提升其耐震能力，而在進行耐震補強之過程，補強成本則為設計者必須考量之因素。
本研究係透過蒐集國家地震中心校舍耐震資訊網中校舍耐震補強之實際案例，並將彙整所得之實際案例內容，藉由相關性與價值分析，以探討補強工程成本與耐震效益之關係；經本研究統計得知國內中小學校舍約38%的補強採取增設翼牆工法，約22%採取擴柱工法，而約14%採取增設剪力牆工法；另根據本研究各種分析結果顯示，校舍耐震補強工程之成本與補強效益相關性並不強烈；若依本研究所定義之補強提升程度及補強效率與補強成本進行四種價值分析，研究結果顯示價值最高者為增設剪力牆工法，其數值介於3.07至6.53，其次為增設翼牆工法，其數值介於2.21至4.93，價值最低者則為擴柱工法，其數值介於1.81至4.12。

After the painful experience of the 921 Chi-Chi earthquake which occurred in 1999, Taiwan applies the performance-based seismic design which is a new generation of seismic research in the international, and conducts research of performance-based seismic design, this concept is not only used in the design of new buildings, but also affects the assessment and design of seismic retrofit. School buildings are the gathering place of students for class, and also are the place for emergency evacuation of people in the region when suffered a serious disaster. Therefore, the seismic capacity of the school buildings is extremely important, but because most school buildings are built in the early years, so the seismic design is inferior to today's specification, thus many school buildings have to concern their seismic capacity. With the development of related research in seismic, school buildings can be based on seismic capacity assessment to determine whether reinforcing or not, and use seismic retrofit to upgrade its seismic capacity. However, during the seismic retrofit process, the reinforcement cost is a consideration factor for designer.
This study will collect practice projects of school building seismic reinforcement and compile the contents of the actual case, then uses value analysis and canonical analysis to explore the relationship between the seismic retrofit costs and benefits. According to research statistics, there are 38% of the reinforcement case used additional wing wall construction method, 22% of the reinforcement case used expansion column construction method, and 14% of the reinforcement case used additional shear wall construction method. Based on variety analytical results of this study the correlation between seismic retrofit costs and benefits is not strong. Four kinds of value analysis in accordance with the degree of reinforcement enhanced comparing to the efficiency of reinforcement or the seismic retrofit costs, the studying results show the highest value is additional shear wall construction method, its value is between 3.07~6.53, the second is additional wing wall construction method, its value is between 2.21~4.93, the lowest is expansion column construction method, and its value is between 1.81~4.12.
