The suspended glass system with pre-stressed cable truss (SGSPCT) is widely started to apply after the 1980’s with Serres building. The advantages of these systems are to provide the transparency on the fa?ades and speedy construction process with minimum materials. The disadvantages are: more expensive than other systems and so many details for the joints and load distribution calculations. There are three different architectural design typologies of the SGSPCT system. These are distance bridging systems, between floor system and independent body. These three different typologies can be seen on the same building at the same time. This system has been known as complex structure systems. The twenty five glass buildings which are designed in different systems have been analyzed during this study. After these analyses the five glass buildings which are designed with cable-truss system have been selected for scope of the study. These selected buildings have been included of three different cable-truss system typologies and degree. The methodology of this study is literature survey and building analyses method. The written and visual documents involve books, theses, reports, articles, magazines, drawings, internet sources and applied connection details of the glass buildings. The selected five glass buildings have been detailed analyzed with their architectural drawings, photographs and details. The study consists of five chapters including the introduction chapter. The general information of the glass building and cable-glass system has been mentioned in the first chapter. The structural features, details and analytical information on systems have been explained of the selected buildings in the second chapter. The detailed analyses of these selected buildings have been done according to their schematic drawings with the plans, sections and load distribution in the third chapter. The fourth chapter is discussion section. In this section, cable-truss systems have been compared with their advantages and disadvantages to the other systems. The fifth chapter is the last chapter, many advantages of cable-truss systems have been concluded that the use of glass substrates.展开更多

Because of its large deflection and high nonlinearity under wind load, the dynamic performance of the cable net is greatly different from that of the conventional linear structures. The continuous membrane theory is used to construct the nonlinear vibration differential equation of the cable net, and the harmonic balance method is used to solve the analytic formula of the nonlinear frequency. In order to verify the accuracy of the above analytic formula, the results of the formula and the nonlinear FEM time-history method are compared and found to be in good agreement. Furthermore, the nonlinear vibration differential equation and the nonlinear frequency obtained in this paper are the basis for the wind-induced response analysis of a cable net under fluctuating wind load.展开更多
