THE DESIGN OF COMPLEX SINGLE LAYER CABLE NETS AND ANALYSIS OF PRESTRESS CONTROL TECHNOLOGY FOR POINT SUPPORTING GLASS BUILDING

With the introduction of prestress technology, the curtain structure is used widely for its large scale, light weight and fine transparence etc. Now the flexible support system including the cable nets has became the main structure of glass curtain. Referring to the design Scheme of single-layer cable nets of Beijing New Baoli Mansion by King Special Glass Engineering Co.Ltd, this article gives the analysis of the test model of complex single-layer cable nets with main and secondary cables by finite element analysis software. The authors also simulate the process of applied prestress of this test model and give some important references to the design and the construction of the real project.
