中文摘要 | 街屋之數量龐大,很難全面進行專業之耐震評估。若能經由民眾的自主檢查,先篩選出耐震能力有疑慮的街屋,再交由專業者進行詳細評估,此較具可行性。故而一個簡單的街屋快速評估工具,確實有其必要。由於校舍與街屋具有相似的結構特性,且校舍已有大量之詳細評估結果,故可使用統計的方法,將校舍的耐震詳評結果應用在街屋上面。國家實驗研究院地震工程研究中心利用1,187棟校舍耐震詳細評估資料庫,對每棟校舍的總樓地板面積、柱量以及經詳細評估後得到的耐震性能地表加速度進行統計分析,獲得每棟校舍之柱量比與耐震性能的關係。再以等值柱量的轉換概念,將磚牆及RC牆對耐震性能的貢獻予以適度考量,因而發展出低矮型鋼筋混凝土建築物的耐震能力快速評估方法。本研究利用過去地震勘災紀錄,建立59棟低矮型鋼筋混凝土建築震損資料庫,並以此震損資料庫驗證本快速評估法,驗證結果顯示震損程度為中害以上者,評估結果皆為耐震能力有疑慮。然而快速評估結果為耐震容量不足者,仍有一部分屬於小害以下,顯示本方法確實具有篩選性及保守性。以本方法對145棟台灣典型街屋進行快速評估,約有四成的街屋須後送進行專業詳細評估。因此本方法可做為民眾住家自主檢查之工具,協助其篩選出耐震能力可能有疑慮之街屋,再尋求專業之詳細評估與補強設計,而為一個經濟可行的做法。 |
英文摘要 | It is extremely difficult to carry out the seismic evaluation by professionals for allthe street houses due to huge volume in Taiwan. Therefore, rapid evaluation carried out by ownersas a preliminary screening can be a feasible scheme. Those buildings labeled with safety concernby rapid evaluation can be further evaluated by professionals. Sincethe school buildings and the street houses in Taiwansharethe samestructuralcharacteristics, the empirical formula of seismic capacity for school buildings obtained throughdetailed evaluation can be applied to street houses. Based on the seismic evaluation data of 1,187 school buildings of the database collected bythe National Center for Research on Earthquake Engineering, anempirical formula of the performance ground acceleration and the column-to-floor area ratio was established. The cross sectional areas of brick infill and RC wallcan be transformedinto theequivalentarea of column according to their seismic capacities. Consequently, the performance ground acceleration of a low-rise street house can be rapidly evaluated by the ratio of column sectional area to floor area of building. The seismic rapid evaluation method has been verified by the data bank of damaged buildings collected through earthquake reconnaissance. The seismic capacities obtained from the rapid evaluation method correlate well with the damaged status of low-rise buildings. In general, the rapid evaluation method is conservative but still possesses a screening capacity. This paper presents a method for building owners to roughly evaluate the seismic capacity of their buildings by themselves. |
