【Abstract】 Combining with the supporting system of the glass curtain of Shanghai Grand Theatre, the working principle of such a new form of supporting system—Prestressed Cable Truss is discussed. Static analysis about a typical segment of the cable truss is processed and some assumptions are presented. Based on it,one design method is put forward.In the end,some construction methods are briefly introduced.更多还原
