Hey, I am a PhD student of structural engineering at Drexel University. My filed of research study is numerical modeling of complex bridges subjected to spatial ground motions, but I am also interested in the following areas: Wave soil structure interaction; Structural control and health monitoring; Structural risk, reliability and safety; Concrete and steel structures; Performance based design; Nonlinear analysis of structures, and Structural dynamics and random vibration. I have created two pages in Wikipedia named "Earthquake rotational loading" and "Rotational components of strong ground motions" based on my master's thesis, and I am going to create more pages here along my research studies.
