Smart City and Civil Engineering Applications
The concept of Smart Cities has been introduced to categorize a vast area of activities to enhance the quality of life of citizens. A central feature of these activities is the pervasive use of Information and Communication Technologies, helping cities to make better use of limited resources. Indeed, the ASCE Vision for Civil Engineering in 2025 portends a future in which engineers will rely on and leverage real-time access to a living database, sensors, diagnostic tools, and other advanced technologies to ensure that informed decisions are made. Smart Structure Laboratory seeks to develop innovative ways to enhance the quality of life of citizens. Beyond providing convenient life such as smart home, our goal is to develop safe, secure, and sustainable society by using cutting-edge technology.

Vision based pedestrian suspension bridge health monitoring
영상 기반 모션 센싱 기법을 이용하여 보도현수교의 안전성을 평가하는 솔루션을 개발 중입니다. 별도의 센서 부착 없이 영상 촬영만으로 보도현수교에 가해지는 하중과 그에 따른 변위를 측정하여 보다 효율적이고 적은 비용으로 보도현수교의 상태를 예측하고자 합니다.

Vision-based Structural Health Monitoring
Vibration-based Structural Health Monitoring (SHM) is one of the most popular solutions to assess the safety of civil infrastructure. SHM applications all begins with measuring the dynamic response of structures, but displacement measurement has been limited by the difficulty in requiring a fixed reference point, high cost, and/or low accuracy. In Smart Structure Lab, a vision-based approach is being explored, especially with commercial off-the-shelf technology including Unmanned Aerial System (UAS), cameras, and Microsoft Kinect sensor.

Post-Disaster Response
In the minor to moderate natural and man-made disasters, such as earthquakes and fires, people may be trapped inside the building and hurt by the disaster. Considering the trapped victims may be unconscious, there is a big demand of emergency responders to get information on the locations and physical statuses of trapped victims inside a building under disaster. Smart Structure Lab explores methods to help the first responders and the victims using devices such as smartphones, cameras, and wearable devices.
Student-centric Cyber-Physical-Systems
Due to the nature of real-world problems in civil engineering, students have had limited hands-on experiences in classrooms. To address this challenge, the Smart Structure Lab works on developing a new interactive learning tool to bring real-world problems in civil engineering into classrooms that promotes physical interaction among students and enhances their engagement in classrooms.
