The applied structural dynamics lab (ASDL) analyzes the dynamic response of civil infrastructure such as bridges, power plant structures, and buildings through the rigorous dynamic analysis and advanced real-time testing. The major research interests of ASDL include, but not limited to, structural vibration control, seismic performance evaluation of structures, nonlinear dynamic analysis, and real-time hybrid simulation (RTHS). In particular, RTHS is a very efficient testing method for analyzing the response of large-scale structures under earthquake loads. Since only the structural component of interest, which is difficult to be analytically analyzed, is physically tested and the rest of the structure is numerically modeled, RTHS enables a large-scale dynamic testing with a relatively low cost. The substructuring concept of RTHS can be extended to the areas of wind engineering and coastal engineering so that the aeroelastic behavior of bridges or the coastal structure subjected to both wind and wave loads can be also effectively analyzed using RTHS. Furthermore, ASDL will expedite the development of robots that can be used in a high-risk construction site or disaster area by using its unique real-time displacement/force control algorithms which are the core elements for high-speed motion control of humanoid robots.
