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.

Soft Story Risk Reduction: Lessons from the Berkeley Data
A Special Projects and Initiatives report to Earthquake Engineering Research Institute
Executive Summary:
In 2005, the city of Berkeley, California began a mitigation program to address earthquake risks posed by certain residential buildings. The program required seismic evaluationsof several hundred multi-unit woodframe buildings using specific engineering criteria.
The targeted buildings had been pre-selected as “soft story” buildings based largely on their appearance. This report describes a study of the program’s technical findings, asking this question: How well do visible indicators of soft story deficiencies predict the
results of detailed evaluations of those same suspect buildings?
In particular, the study hoped to derive a screening tool based on readily observable conditions. Such a tool would facilitate mitigation programs for so called SWOF (soft, weak, or open front) buildings in other jurisdictions.
But we found that no such tool exists, in part because the reported Berkeley data was too inconsistent to support statistical correlations, and in part because the traditional engineering metric, the weak story ratio (WSR), is inherently flawed as a performance predictor. So while the initial goal could not be achieved, the study did make a number of useful findings that offer lessons to engineers and mitigation planners.
