2004, 34(12): 6-11. doi: 10.13204/j.gyjz200412002
Abstract:
Because of the merits of the integral hoisting in structural construct ion, i.e., simple construction instrument applied, assembling on the ground, hig h efficiency and safety, it has become the main special approaches for long-spa n steel structure construction recent years. It should be noted that during the p rocess of integral hoisting of steel structure, its displacement and stress dist ribution in the structures differ from their design condition, and the checking of stability and strength of members or structure become necessary. Some strengt h or stability-reinforce approaches to some members or structures must be emplo ye d for their construction safety. This paper presents the design of integral hois ting project of China southern airlines aircraft hangar and the structural techn ology problems involved in integral hoisting process. The integral hoisting proc ess and their details for this hangar are also described and discussed.

Abstract:
Shenzhen Convention and Exhibition Centre is one of the most important municipal projects of Shenzhen. The steel arch structure with double box-girde r s is used in the roof-structures. To decrease the horizontal acting forces on t he main-structure produced by arch self weight and to meet architecture requir ements, pre-arch and special construction technology are employed. The arch str u cture is hinged in one end and sliding in another during the assembling, and fin a lly it is totally fixed in both ends after the horizontal sliding is finished. F urthermore, lateral instability checking of the steel arch structure due to wind is done for the double box-girders in the first stage of construction. Finally ,an initial analysis of steel-bar used as tensile rod in the roof-struc tures is also conducted.

Yan Fuyou, Jia Xin, Yuan Yong
2004, 34(12): 59-60,97. doi: 10.13204/j.gyjz200412016
Abstract:
The anchorage performance of GFRP rock b olt is studied by the material test of GFRP threaded rod with a diameter of 25mm and its pull-out test of grouting anchorage. The study shows that the tensile capacity of GFRP threaded rod is higher than that of a steel bar with same diame ter, yet its potential can not be in full play. It is indicated by the pull-out test that the load-slip curve of GFRP material is also similar to that of a th readed steel, but its maximum pull-out force is about 30% less than the latter, which shows that the superiority of GFRP material can not be in full play by or dinary mortar anchorage.
