Key word: Assessment of damage from earthquake, 3D street scanner, TELES
Outline
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.
