Performance evaluation of steel structure
Structure Design and Analysis
Application of high performance materials
From the observations of the past earthquakes, seismic damage not only cost life and property loss but also affects the functionality of buildings. The HPSL proposes new alternatives to enhance the seismic performance and seismic resilience for the existing and new constructed buildings. The recent researches are as below:
Seismic performance of steel moment resisting frame relays on the strength and ductility of connections. To prevent the damages including fractures or plastic behaviors of connections and the residual deformation of structure that caused by the serious damages of connections, connections with self-centering capability were proposed and evaluated experimentally. In the design, structural members such as column and beam could remain elastic and no residual deformation was observed even after a very large deformation.
In the past earthquakes, over 90% of the damaged structures are below 6-story and most of them are residential buildings and houses. Base isolation has been proved to be an high performance approach to enhance the seismic performance of the buildings. Due to the cost and maintenance demand, the base-isolated systems are mostly applied to critical facilities such as hospitals and public infrastructures. For the low-cost apartments or houses, a movable base system could be more cost-efficient. In the study, common construction materials have been adopted on the base supporting interface to develop a simple sliding mechanism. Performance under various levels of shaking intensities has been confirmed experimentally.
Dieh-Dou type and Chuan-Dou type timber frames are the major types of the traditional timber frames in Taiwan. In the 1999 Chi-Chi earthquake, these traditional timber frames sustained severe damages. Experimental studies have been conducted to evaluate the seismic behaviours and to verify the proposed mechanical model. The research objectives are to develop the seismic performance evaluation method and the enhancement technologies for the timber frames.
