Several damage mitigation studies have concluded that wind-induced fatigue may be responsible
for the extensive damage to roof cladding. This paper presents the application of the
recently proposed novel simulation methodology, capable of generating both Gaussian and
non-Gaussian wind pressure ßuctuations, in the fatigue analysis of roof cladding. After establishing
the simulated fatigue characteristics of roof pressures, the total fatigue loading has been
estimated by integrating the long-term wind climate with the simulated fatigue characteristics of
roof pressures. Simulated results are compared with predictions made by Rayleigh, Gaussian
and Weibull models as well as German and British recommendations. The study indicates that
non-normality can signiÞcantly increase the rate of fatigue damage accumulation, and, if
neglected, it can result in non-conservative fatigue life estimates

Literature on turbulence modeling is rich in empirical, semi-empirical and theoretical spectral equations whose parameters assume deterministic values. Starting from a critical review of the state of the art, a unitary model of the 3-D atmospheric turbulence was proposed where all parameters are defined by first- and second-order statistical moments derived from a wide selection of experimental measurements. Analyses based on Monte Carlo simulation of the model parameters show that the propagation of turbulence uncertainties over the windexcited response of structures gives rise to a relevant scatter. The passage from Monte Carlo simulations to Taylor series expansions addressed to apply the first-order second-moment technique provides systematic rules to deal with the structural response in a full probabilistic environment. It also allows appreciation of the role of each uncertain parameter. The joint application of this procedure and a closed form solution of the response drastically reduces the computational burden and makes these analyses operatively possible. The proposed approach is a step forward towards the formulation of a unitary probabilistic model of the wind-excited response of structures, comprehensive of model errors, parameter uncertainties and parameter randomness

Comparison of the Strength Design and Prevention Method of Elephant Foot Buckling Among Countries’ Standards of Oil Tanks
Author: Zhiping Chen, Bo Sun, Chulin Yu, Zhou Fang and Ming Zeng | Size: 1 MB | Format:PDF | Quality:Original preprint | Publisher: ASME | Year: 2009 | pages: 6
In China a large number of tanks whose volumes are greater than 100000 m3 are necessary to be built for establishing the oil reserves system with four levels, which include national strategic oil reserve, commercial oil reserves in the three major oil companies, oil reserves in local governments and general enterprises. Oil tanks built in China were mostly welded tanks and on the ground. The difference among the methods of the strength design of the tank side plate designed by countries’ standards such as API 650, JIS B 8501, BS EN 14015 and GB 50341 is discussed. And the reason why API 650 is used by China engineering company is given. Then kinds of prevention methods about the tank wall elephant foot buckling by earthquake which were designed according to different national standards are compared. It is pointed out that the calculation methods of the tank wall’s allowable compressive stresses and longititude compressive stresses designed by national standards are different. At last the existing problems and the appropriate solutions are analyzed briefly.

On April 14th, 2012, “The 7th International Conference on Advances in Steel Structures in conjunction with IJSSD Symposium on Progress in Structural Stability and Dynamics”, jointly hosted by Hong Kong Polytechnic University and Structural Division of Hong Kong Institution of Engineers， and organized by Southeast University, was held in Nanjing International Conference Hotel. The opening ceremony was presided over by Professor Shu Ganping, deputy dean of School of Civil Engineering, Southeast University. Vice President of Southeast University, Professor Liu Jingnan attended the conference and gave the welcome speech. Many directors from relevant schools and departments, including Wu Gang, dean of School of Civil Engineering, also attended the conference.
This conference aims to promote international exchange and negotiation, strengthen the cooperation between scholars around the world in the field of steel structures, and facilitate the development of steel structures, steel—concrete structures and aluminum structures, etc.. More than 200 experts and scholars in the field of steel structures world-wide attended this conference, 75 of whom are from countries and regions such as the US, UK, Japan and Hong Kong. The successful holding of this conference would further elevate Southeast University’s international influence on civil engineering, steel structures and other relevant fields.
