The Performance Research And Optimizes Of A New Tensile Spatial Structure

With the living standard improve, culture, sports, industrial production enter unceasingly improve, The people strengthened to the spatial structure,In particular great span high performance spatial structure demand, thus promoted the great span spatial structure in our country's swift and violent development. then with actual project quantity increase, the spatial structure situation tends to the diversification, its corresponding fundamental research and the design technology also gradually tend to the consummation.In recent years, develops out many new space steel structure system on the basis that steel structure developing in the prestressing force technology and space, Beam String Structure(BSS) construction is one of which. Beam String Structure(BSS)construction is that only a kind of representative prestressing force developing demands pole structure , it has many merit over the past few years. Countries such as Japan has developed a kind of new space strain structure , it has been that a kind of s space strain structure being composed of structure such as space prestressing force rope net , Beam String Structure(BSS)(Pro. M.Saitoh intitule SKELSION structure system), that structure is on the basis bringing strain the string girder construction merit into play sufficiently then on strain the string girder construction basis,the structure merit having brought the space prestressing force rope net into play , feasible structure structure is stabilized especially rationally, especially by the force. Be structure's turn to belong to starting phase still in our country, the function studying the person accepts a force has important significance to guiding project practice.The paper take FEM as basis, pulling structure geometry nonlinearity sum state combining with space the nonlinearity characteristic, makes use of the finite element method software ANSYS nonlinearity module being applied or used universally to carry out simulated analysis on this space structure. Main job as follows: first, applying the software ANSYS life and death element methed and APDL, the structure being in progress to whose space rope net and strain the string beam looks for a shape. Then analysis the mechanism and characteristic of thestructure on whose accepting under snow load , the wind load effect, with Time History analyzes,research the effect of space rope net tension ,the arrangement space rope net and BSS sag ratio to the responding to the earthquake,find a conclusion. finally,uesing APDL of the software ANSYS, according tobe a target most with material, carry out structural optimization on considering the standard basis of relevance , discuss that the space rope covers the design that tension , space rope net arrange to wait for an impact of parameter over optimization result in advance.According to the paper research , get structure's to new model Tensile Space to accept the cognition that force characteristic property has had to go a step further, for engineering design with the future provide certain theory reference basis.
