SHM benchmark problem was issued

E-mail Print PDF

SHMC is sharing a benchmark problem based on a real bridge with the SHM community. This benchmark problem has completed recently. The data used in this problem were collected by an in-situ structural health monitoring system implemented into a full-scale cable-stayed bridge before and after the bridge was damaged, which is very rare in structural health monitoring field.

E-mail Print PDF

A new research article, co-authored by Hui Li, Shujin Laima, Qiangqiang Zhang, Na Li, Zhiqiang Liu is published in the Journal of Wind Engineering and Industrial Aerodynamics. In the article, a large number of monitoring results of a long-span suspension bridge, including wind field, wind pressure field and wind-induced vibrations, were displayed and analyzed. Moreover, the validations for wind tunnel tests were also performed.

New research article of SMC: Conduction of water molecules through graphene bilayer.

E-mail Print PDF

A new research article, co-authored by Yu Qiao, Xiang Xu and Hui Li is published in the Applied Physics Letters (IF=3.8). In this article, based on the previous experimental research, water conduction across a two-dimensional (2D) graphene bilayer was investigated through molecular dynamic (MD) simulations. Different from one-dimensional (1D) nanofluidics in carbon nanotubes (CNTs) where CNT chirality has only a secondary effect, when the bilayer structure is changed from the turbostratic state to the commensurate state, the water infiltration pressure decreases considerably, as energy valleys are formed. Compared with the 1D nanofludics in a CNT, the infiltration pressure of 2D nanofluidics in a graphene bilayer tends to be much lower, primarily because of the additional degree of freedom of water molecular motion. This research may provide a foundation to develop the next generation 2D nanobumper and nanomotor. Figure 1 shows the 2D nanofluidic system MD model and the infiltration isotherm curves of the 2D nanofluidic systems as a function of the rotation angle. Figure 2 shows the interactive potential energy distributions in graphene bilayers.
