Center of Structural Monitoring and Control

2012 is coming! On behalf of the director of SMC, Prof. Jinping Ou, I would like to express my warm congratulation on the achievement and progress in our research made in 2011. I greatly appreciate your efforts and contributions in 2011.

Structural health monitoring group, Yuequan and Xiaocheng have developed automobile wireless sensors and data loss recovery approach by using compressive sensing technique. Wensong, Wentao and Biao have investigated wave propagation–based sensing technology including scour monitoring by ultrasonic technique, piezo-electric active and passive monitoring technique, piezo-eletric fiber composites, and time-frequency features of the signal. Guofu continuously focused on corrosion sensors-based on electro-chemical process. Huigang continuously investigated cement and epoxy-based composites containing nanomaterials aiming at the distributed sensing networks. Chuan designed a new FBG-based monitoring system for localization and speed measurement of vehicles. Optical fiber sensing technology was re-starting in our center. More importantly, Shunlong, Yuequan, Yang, Yong, Fujian and Yiming have forwarded to mathematics-based approaches in data processing and data mining (e.g. Bayesian compressive sensing and self-healing of the recovery data, extreme value estimation models, etc). Dongwang proposed fractal-based seismic localization approach for building structures. Shujin continuously focus on monitoring wind and wind effects of long-span bridges.

Structural control and hybrid simulation group, Huaibing focused on a key technology of implementation of active mass damper on Guangzhou New TV tower (Collaborating with Prof. Fulin Zhou’s group), and hybrid simulation approach has been proposed and validated, which is a useful tool for performance investigation of large control devices. Jian has proposed de-centralization control algorithm-based on intelligent artificial techniques for nonlinear hysterestic structures, its stability and robust have been proven. The control considering soil-structure interaction has been performed on shaking table by Jian. Buckling restrained braces and shear steel plates are on-going research topic investigated by Bin, Jilong, Ning and Junxian. Bin also made a great progress on real-time hybrid test technology.

Materials group, Xinchun and Yonghu made a good start on self-energy harvesting materials, which is a hot point in material science. Hopefully, a great progress will be made in 2012. A smart MR damper with the self-energy harvesting technology will provide an example on potential solution of passive adaptive smart devices. Xiaoyan continuously focuses her research on magnetoelectric coupling in multiferroic heterostructures and has obtained good results. Xiang has made great progresses in nano-fluids, aiming at more efficient energy dissipation devices. Suchao and Chenxi have developed shape memory alloys-based rubber, performance and modeling have been investigated. Guijun focused on fiber reinforced polymer (FRP) composites, and later will provide a potential green solution on civil engineering materials with plant fibers. Zhenyu has made good works on FRP reinforced structures. Huigang starts on the multi-factor coupled effects of durability on nano-concrete.

Wind and fluid engineering group, Shujin has comprehensively investigated the vortex-induced vibration of bridge deck and control, and interesting findings have attracted more and more attention. Wenli performed good research on multi-mode vortex induced vibration of cables. Bio-inspired boundary layer fluid control and aerodynamics-based active control of bridges are ongoing research topics by Wenli and Dabo. Peng has made a first step on simulation of rain-wind induced vibration of cables. Anxin starts his new research topics, including bridge damage subjected to earthquake and tsunami, and bridge behavior subjected to wind and wave coupled actions. Wensong proposed damage identification of wind-turbine blade, which is a challenge topic because the modal parameters are influenced by the rotation speed of the blades. Shujin, Wenli and Wensong have found a similar phenomenon on the aerodynamic properties of bridge decks, cables and wind turbine blades.

Earthquake Engineering group, Anxin continuously focuses on the pounding and unseating of bridges subjected to earthquake ground motion. Lizhe has made a good work on loss estimation of infrastructures under strong earthquake attacks. Seismic damage evaluation and retrofit of seismic-damaged structures post-earthquake events are conducted by Gao.

Application and industrialization group, Liangquan, Qingli, Chuan, Xinchun, Anxin and Jian have contributed a lot to the application and industrialization of our new technologies and products. Bin, Junxian, Xinchun, Anxin, Chunwei, Huaibing, Dongyu and Jian contribute a lot to preparation of the Design Guidelines of Structural Vibration Control.

Yue makes a great contribution to the daily affairs of our center. Wensong takes his efforts and time on the management of our website and Lab instruments. Xinchun, Anxin, Guijun and Wenli contribute a lot to the management of our Labs.

Once again, I greatly appreciate your efforts in 2011 and wish we will make more progress in 2012.

Here, I am looking forward to a bright and prosperous 2012 of SMC, our brothers- and sisters-in-academy in Dalian University of Technology, and Shenzhen Graduate School of Harbin Institute of Technology.
