Wind-Resisitant Research Of Single-layer Cable Net Glass Curtain Wall

In recent years, single-layer cable net glass curtain is adopted widely due to its simplicity and limpidity. It is sensitive to wind loads, but research of the dynamic characteristic of this kind of structure is only a few. So it is very exigent to wind-resistant research of single-layer plane cable net glass curtain.Take Sichuan Investment Corporation Dispatching Center as an example, this paper studies and solves the following problems:(1) Drape of horizontal cable:It uses form-finding, to find the reasonable and initial shape of cable net,and ensure the transverse cable is horizontal after installing glass.(2) Pretension optimization of vertical cable: According to the features of wind load distribution and cable net deformation, it optimizes the pretension distribution of cable net. It also optimizes the tension distribution of vertical lable, make uniformly forced and minimizing warpage.(3) Glass warpage: It weakens the stiffness of single-layer cable net, obtains the warping deformation distribution of glass. Through precision finite element analysis of glass stress, it ensures every piece of glass stress are required to the specification, after taking certain measures.(4) Wind-induced incentives of single-layer cable net: the analysis shows that the the results of dynamic analysis is smaller than static analysis.The paper brings out the controlling requirement of label's pretension tensioning, referencing the similar engineering design and acounting the finite element analysis of glass stress. In order to smooth implementation and guaranting quality, it suggests that making mechanical properties experiment of cable, ensuring the consistency of calculation model and practical mechanical properties of cable before implementation...
