| 摘要: | 台灣位於地震板塊交界處，長期受到地震之災害，老舊建築物街區更因建築物耐震強度資料久遠或遺失導致，建築物耐震評估難以快速建立，本研究旨在以3D掃描街景車快速建構TELES建築物震損評估系統所需建築物之構造種類、年代、用途、樓地板面積、棟數、樓層數等資料，進行迪化街歷史街區人員損傷與建築物震損結果。
本研究使用TOPCOM IPS2街景車掃描迪化街歷史街區建築物，以四種構造種類(土造、木造、磚造、石造、鋼筋混凝土造)、不同建造年代建築樣式如仿洋樓紅磚街屋、盛文藝復興牌樓厝街屋、現代主義國防色面磚街屋以及70年代以後以退縮建築、不同建築物用途與樓地板面積(住宅、 商業、工業、農業、非營利、政府機關、教育)、及不同棟數與樓層數為變項，匯入TELES建損評估系統評估不同構造種類不同建造年代不同建築物用途樓地板面積及不同棟數與樓層數之人員損傷與建築物震損。
研究結果顯示迪化街南京西路民生西路段耐震能力，比整個永樂里歷史街區更易於受震損；為避免強震作用人員損傷與建築物震損因提早補強。也發現出低樓層木造房屋，在6級與7級規模地震，耐震程度佳，甚至比低樓層鋼筋混凝土建築物耐震。
對於TOPCOM IPS2街景車掃描能以最快速最高效率的方式，達到資料全面性蒐集的好處。對於未來各種建設規畫TOPCOM IPS2街景車都能有突破性的運用。以往過去建築物、地區等探勘，都是查哪裡看哪裡，漏哪裡補哪裡往往浪費許多不必要的人力成本與時間，但藉由TOPCOM IPS2街景車就能已突破性的，將完整資訊內容全部儲存，不管需要任何新的資訊，都能夠以最快的速度搜尋出不足的資料。
Located at the junction of tectonic plates, Taiwan has sufferred from the earthquake over a long period of time. Information about resistance to earthquake of old communities were not easy to keep because of ancient data, therefore, assessment of aseismatic ability for those architectures located in old communities cannot be performed easily. This research is mainly focus on how to simulate structural damage from the earthquake in Dihua Street by TELES whereby architectures in different styles, ages, use, floor space, quantity and stories of buildings established with 3D street scanner.
We hereby scanned a part of Dihua Street, an old community, via TOPCOM IPS2 street scanner for TELES with variation through styles(Brick, Reinforced concrete, Reinforced brick and Wooden) , ages(Imitation of Western-style red brick street houses, Sheng Renaissance arches house, modernism defense colored brick street house,and 70 years after construction to flinch) , use(residence, business, industry, agriculture, NPO, government and education), floor space, quantity and stories of buildings.
The result shows that the aseismatic ability of Dihua Street from Nanjing West Road section through Minsheng West Road section is weaker than the whole Yongle Village. It is suggested that starting strengthen works of architectures earlier, especially before any damage occurred from the earthquake. Another fact to be notice is that lower-storied wooden building shows better aseismatic ability at an earthquake measuring 6 to 7 on the Richter scale, ever better than lower-storied Reinforced concrete building.
The advantage of TOPCOM IPS2 street scanner is fast, efficiency and complete in data collection and is well-suited for any kind of construction planning process. In old days, data collection during construction project is time-wasting and there was pretty much restraint, however, with TOPCOM IPS2 street scanner, data colletion is no more bother nowadays. All data of architectures are recorded in the database for further use in the future. |
