The following conclusions were obtained from the analysis results:(1)the rationality and effectiveness of the presented nonlinear multi-node sliding cable element was verified for both sliding and non-sliding situations; (2) with the sliding of the latitudinal cables, uniform axial force distribution can be achieved for the tensegric system of the Suspen-Dome, which is helpful for improving the material efficiency of the cables and preventing the cables from sagging under asymmetric loads;(3) whether the latitudinal cables can slide or not has little effect on static behaviour and nonlinear stability of the single-layer lattice dome even under asymmetric loads.

Introduction Steel reinforced concrete structure is a new structure, which is better than steel structure and reinforced concrete structure .Due to the large stiffness, high carrying capacity, good seismic performance, etc. it is widely used in engineering [1]~[3] .And FRP (fiber reinforce polymer) with a corrosion-resistant, high strength, light weight, good durability are being increasingly applied to civil engineering structures.Steel reinforced concrete structure strengthened with FRP can further make full use of the material properties, reduce the section size, increase the usable floor area of the structure ,are able to meet the needs of modern structure which is large-span, heavy-duty and high-rise.At present, the application and research about FRP focused on reinforced concrete structure strengthened with FRP in civil engineering, to be less for steel reinforced steel concrete structure strengthened with FRP.Therefore, according to several kind of destruction
