The galloping of iced conductors is a serious threat to the safety of transmission lines. A two-nodebar element having three translational and one torsional degree-of-freedom at each node was employed to model the conductor. Combining with the method of the bundle conductor equivalence to a single conductor, the finite element model of multi-span transmission line for galloping analysis was established. In addition, the aerodynamic coefficient of iced conductor under different wind attack angle was obtained by using computational fluid dynamics method. On the basis of the finite element model and aerodynamic coefficient curve, the Runge-Kutta method was applied to carried out nonlinear numerical simulation of iced conductor galloping and the FORTRAN program was compiled. The galloping of the long-span transmission line crossing Hanjiang River was analyzed. The results indicate that the presented method and program are reliable and efficient. Meanwhile, the impact of the wind velocity and initial attack angle on galloping were investigated with the program. They canprovide references for the further study of galloping.

In this work, the photochemical degradation process of 17β-estradiol (E2) in a suspension of natural montmorillonite (NM) has been studied. The addition of the iron complexing agent ethylenediamine-N,N′-disuccinic acid (EDDS) to the suspension was investigated and compared with the system without EDDS. The effects of the main physicochemical parameters (pH, EDDS, oxygen and NM concentrations) on E2 degradation in NM suspensions were also investigated. In order to better understand the photochemical process, experiments were carried out in the presence of 2-propanol. In general, the photochemical efficiency of the E2 degradation is better in EDDS-NM suspensions than in NM suspensions, especially at higher pH. This work demonstrated that the NM-EDDS system is an interesting and valuable research area and could be considered as a promising photochemical system for wastewater treatment.

As urban development extends to underground space gradually, more and more deep foundation pits with complex surroundings, more nearby buildings and deep excavation occur. The reinforced concrete circular bracing system has the advantages of reasonable load transfer, small deformation and convenient earth excavation, and it is widely used in urban deep foundation pits. Based on the experience of design and construction of foundation pits, some important problems needed to be considered during design and construction of foundation pits are analyzed, such as bracing stiffness, layout of corner bracing, calculation of bracing columns, crack control and static detonation of bracing system. The reasons of the difference of deformation between design and monitoring values are discussed. The results have direct reference value for the design and construction of reinforced concrete circular bracing system in urban deep foundation pits.

To provide a reference for the design and application of concrete beams reinforced with hybrid (FRP and steel) bars, comparative analyses among different existing calculation formulas for flexural strength were performed. The comparison between the theoretical results and experimental results verified the accuracies and validities of these formulas. The influences of allowable ultimate tensile strain of longitudinal reinforcement on the theoretical calculation results were discussed based on theoretical analysis by changing parameters including concrete strength, strength of steel bar, FRP type, ultimate compressive strain of concrete and effective reinforcement ratio. The results show that existing formulas in calculating flexural strength of concrete beams reinforced with hybrid bars are based on the plane section assumption and the strength can be obtained according to strain compatibility and force equilibrium inside the cross sections. The theoretical formulas can well predict the flexural strengths with small errors. However, the theoretical values are safer when the allowable ultimate tensile strain of longitudinal reinforcement is confined. Therefore, the theoretical formula in which the allowable ultimate tensile strain of longitudinal reinforcement is confined is recommended in the design. © 2016, Editorial Department of China Journal of Highway and Transport.

According to the shake table test results of a high-rising building with large local space, the dynamic characteristics of such structure are complex and the torsional mode becomes the first mode, while the torsional responses under earthquake excitation, especially of the floor just above the large local space, are very remarkable. Special measures are required for such structural system for maintaining its seismic safety. In this research, the bidirectional Tuned Mass Damper (TMD) is employed for reducing the torsional vibration of the high-rising building with large local space. The optimization of the TMD parameters, such as natural frequency, damping ratios and mass ratio, is performed. The time history analysis results indicate that the proposed bidirectional TMD is very effective in torsional vibration control. © (2012) Trans Tech Publications, Switzerland.

Based on the computational fluid dynamics (CFD) software, the method of a two-dimensional cylinder surrounded by unsteady wind flow was used to simulate aeolian vibration of bundle conductors. Firstly, the analysis of unsteady flow around fixed double circular cylinders was performed. The model and the analysis method were verified comparing with classical literatures. Then, based on the moving mesh technology and the programming, the vibration behavior of double conductors under conditions of different supports, spacings and tilting angles was studied. The vertical amplitudes of the sub-conductors versus the reduced velocity were obtained. This study was important for investigation on aeolian vibration of bundle conductors.
