The suspended roof structure of Beijing volley-ball Gymnasium, which was built for 1990 Asian Games, consists of two cable nets, susported on central Cable-arch structure and parabolic-shaped boundary elements. The response of this new type of flexible structure to earthquake load is unknown and should be paid attention to. According to the derived standard devision formula of nodes displacements and internal forces of elements, the analysis computer program was made. The...

The suspended roof structure of Beijing volley-ball Gymnasium, which was built for 1990 Asian Games, consists of two cable nets, susported on central Cable-arch structure and parabolic-shaped boundary elements. The response of this new type of flexible structure to earthquake load is unknown and should be paid attention to. According to the derived standard devision formula of nodes displacements and internal forces of elements, the analysis computer program was made. The responces of displacements and internal forces of the structure to horizontal and vertical stationary random ground motion were analysed. It is concluded that this structure has good property of resisting seismic load.

北京亚运会排球馆采用了由中央索拱体系和两片索网组合而成的新型的屋盖结构体系.这种柔性屋盖结构在未来地震荷载作用下的反应如何,是为人们所不知但却非常关心的问题.作者根据所推导的节点位移及单元内力反应标准差的公式,编制了相应的分析计算程序,对此结构在水平和竖向平稳随机地面运动作用下的位移和内力反应进行了分析研究.

The effects of cables on the instability behavior of the structure hybridized by I section arch and tensile cables have been studied theoretically by using the large deflection(displacement) finite element approach with beam and cable elements, in conjunction with arc length method and Newton Raphson iteration. A full load displacement equilibrium path is obtained, including pre buckling and post buckling equilibrium path. It is found from the load displacement path that...

The effects of cables on the instability behavior of the structure hybridized by I section arch and tensile cables have been studied theoretically by using the large deflection(displacement) finite element approach with beam and cable elements, in conjunction with arc length method and Newton Raphson iteration. A full load displacement equilibrium path is obtained, including pre buckling and post buckling equilibrium path. It is found from the load displacement path that the cables have affect significantly to the structure's behavior, including its limit load carrying capacity and its load displacement paths, and especially they greatly increase the limit load carrying capacity of the hybridized structure by near 40% only in the case of the half span uniformly distributed load. Further more, the effects of rise span ratio on the limit load carrying capacity are also involved in the theoretical investigation. Some conclusions to the design of the cable arch structure are drawn from teh numerical results obtained in the study.

This paper presents an elastic nonlinear buckling analysis of a kind of steel structure hybridized by I section arch and tensile cables. The effects of cables on the instability behavior in the plane of the hybrid structure is investigated theoretically by using the large deflection (displacement) finite element approach in conjunction with the arc length method and Newton Raphson iteration. A full load displacement equilibrium path is obtained, including prebuckling and post buckling equilibrium path. It is found that the cables affect significantly the structural behavior, including its limit load carrying capacity and its load displacement paths. Furthermore, the effects of boundary condition and rise span ratio on the limit load carrying capacity are also involved in the theoretical investigation.
