Abstract
將結構性能的理念導入結構耐震設計與評估，儼然已成為當今趨
勢主流之一。然而，使用非線性靜力側推分析（pushover analysis）來
建立結構物之容量曲線，其設定過程繁複且耗時。本研究以ETABS 8
作為結構分析引擎，並針對ETABS 8 之輸入、輸出格式，建立非線
性靜力側推分析之前處理模組，與耐震能力評估模組，整合出一套建
築物耐震能力詳細評估輔助系統，命名為ACES。在前處理模組方
面，可自動完成定義塑鉸性質、指定塑鉸位置與定義側推分析例之步
驟，然後經ETABS 8 分析模組完成結構容量震譜後，再透過後處理
模組之解析，自動完成結構性能點之求取，並同時得到此性能點所對
應之地表加速度c A 值。ACES 應可適用於各類型鋼筋混凝土建築物，
也應可提升耐震能力詳細評估之效率，進一步降低人為操作的繁複與
可能造成的誤失。
This study develops a computer-aided system for structural capacity-based
aseismic estimation of buildings, named ACES. ACES uses ETABS 8 as its analysis
engine and provides pre-processing and post-processing tools. Its pushover
pre-processing module automates the tedious work on the definition of plastic hinges,
assignment of hinge properties, and setup of the analysis procedure. Once the capacity
spectrum of the structure is successfully established by ETABS 8 analysis module, the
post-processing module of ACES then finds the corresponding ground acceleration of
the structure’s performance point. ACES developed should be applicable to all kinds
of RC building structures and is expected to improve the efficiency of detailed
aseismic estimation on buildings.
