街屋快速評估之驗證

Abstract

街屋建築是台灣常見的住宅型式，也是高震損風險的住宅型式之一。街屋耐震能力快速評估法可以快速評估街屋耐震性能，篩選出耐震能力有疑慮的建築再進行詳細評估，為經濟可行的評估方案。國家地震工程研究中心長期投入研究，開發出街屋快速評估法，供民眾對自宅耐震能力進行自主檢查。作為民眾使用的自主檢查工具，應具有相當的保守性卻又不失其篩選能力，因此本研究利用61棟低矮型鋼筋混凝土建築震損資料庫，以校舍初步評估法及街屋快速評估法進行評估，並由低矮型鋼筋混凝土建築震損資料庫找9棟街屋案例進行詳細評估，藉此比對快速評估的結果與初步評估及詳細評估的結果，可看出快速評估方法的篩選性及保守性。

Street house is the famous type of house in taiwan. It also has the high risk of earthquake damage. Street house fast evaluation can evaluate street house seismic performacne quickly. It can screen the buildings which have concern of seismic safety to execute seismic detailed evaluation. It is an economic and feasible assessment programme. NCREE conducted this research for a long time and developed Street house fast evaluation for people to examine their houses seismic performacne. Being a tool, it should have enough conservative property and screening ability. Therefore, this research used low-rise RC building earthquake-damaged data bank to execute school preliminary seismic evaluation and street house fast evaluation. Furthermore, finding nine street-front buildings from low-rise RC building earthquake-damaged data bank to execute seismic detailed evaluation. By the results of seismic detailed evaluation, the results of fast evaluation and the results of preliminary seismic evaluation were compared. Then, find out the screening ability and conservative property from fast evaluation method is confirmed.
