Zhou Kesong,Deng Chunming,Liu Min

Strategic Study of CAE 2009, Volume 11, Issue 10,   Pages 48-54

Abstract: The results indicated that both WC-17Co and WC-10Co4Cr coated 300 M steel exhibited comparable fatiguelimit and cycles to fatigue failure with those of bare 300 M steel; while the fatigue limit and cyclesto fatigue failure of 300 M steel were decreased by 120 MPa and 70 %~90 % respectively when 300 M steelcrack in chrome plating propagated into 300 M steel, provided as a sub-crack initiator and hastenedfailure of 300 M steel.

Seismic performance of steel MRF building with nonlinear viscous dampers

Baiping DONG,James M. RICLES,Richard SAUSE

Frontiers of Structural and Civil Engineering 2016, Volume 10, Issue 3,   Pages 254-271 doi: 10.1007/s11709-016-0348-8

Abstract: This paper presents an experimental study of the seismic response of a 0.6-scale three-story seismic-resistant building structure consisting of a moment resisting frame (MRF) with reduced beam sections (RBS), and a frame with nonlinear viscous dampers and associated bracing (called the DBF). The emphasis is on assessing the seismic performance for the design basis earthquake (DBE) and maximum considered earthquake (MCE). Three MRF designs were studied, with the MRF designed for 100%, 75%, and 60%, respectively, of the required base shear design strength determined according to ASCE 7-10. The DBF with nonlinear viscous dampers was designed to control the lateral drift demands. Earthquake simulations using ensembles of DBE and MCE ground motions were conducted using the real-time hybrid simulation method. The results show the drift demand and damage that occurs in the MRF under seismic loading. Overall, the results show that a high level of seismic performance can be achieved under DBE and MCE ground motions, even for a building structure designed for as little as 60% of the base shear design strength required by ASCE 7-10 for a structure without dampers.

Numerical investigation on side heat transfer enhancement in 300 kA aluminum reduction cell

WANG Changhong, ZHU Dongsheng, LEI Junxi, ZHOU Jiemin

Frontiers in Energy 2008, Volume 2, Issue 3,   Pages 256-260 doi: 10.1007/s11708-008-0051-0

Abstract: Industrial test and numerical simulation were synchronously applied to analyze the side heat transfer process and enhance heat transfer in aluminum reduction cell. The 3D slice finite element model of aluminum reduction cell was developed, with which the sidewall temperature field of the cell was computed by using software ANSYS. The main influencing factors on heat dissipation were analyzed and some effective measures were proposed to enhance sidewall heat transfer. The results show that the shell temperature of the test cell and the common cell is respectively 312°C and 318°C and the ledge thickness is 16 cm and 15 cm when side coefficient of heat transfer between the shell and the surroundings is 70 W/(mK). With the increase of the side coefficient of heat transfer between the shell and the surroundings, the temperature of the shell decreases but the thickness of the side ledge increases when the electrolytic temperature, the ambient temperature, the coefficient of heat transfer between molten bath and ledge, the eutectic temperature and the thermo-resistance of the side lining are constant.
