Theoretical And Experimental Study On Construction Method Of Construct And Stretching Layer By Layer And The Internal Force During The Construction Process

The Prestressed Cable Supported Lattice Shell(PCSLS) is a new type ofhybridized space structure with half-rigid joints. It consists of a single layer latticeshell as upper chord,some prestressed cables as the bottom chord and oblique barsand some steel tubes as vertical bars. It Combined the strongpoint of single layerreticulated shells and the tensigrity structures,reasonable stress distribution will beobtained in the PCSLS. A new type of construction method is bring forward in this paper. In this methodthe structure is constructed layer by layer and the prestress is apllied correspond to it. Construction processs run-after compution is conducted by Ansys programe. Therules of the internal force and the displaycement of the joints correspondd to the newconstruction method is obtained. In the end,the feasibility of the new constructionmethod is proved by the theoretics and the experimentation. Non-linear increment method is adopted during the computation processs.Element live and dead technic of the Ansys programe is adopted during theconstruction processs run-after computation. Design and complete the model experiment. The correctnesss of the theoretics isproved by the experiment. A few new node and rod forms are brought forward in thedesign processs. A new tensile form of cable is put forword. And the realibility ofthem is affirmed by the experiment. and it can provide reference for engineering。Sawabout the statics characteristic of PCSLS by statics experiment.
