［摘要］山东省文化艺术中心群众艺术馆西南角的空间钢桁架体系是由水平平面桁架与竖向平面桁架组成,该空间桁架可作为大跨度屋面梁的有效支撑，其传递竖向荷载,保证了大跨度屋面的正常使用；又可作为抗风柱，该转角水平桁架受水平风荷载时，两方向的水平桁架可以互相作为支撑将水平荷载传递给主体结构抗侧力构件，同时又保证了竖向桁架的稳定性。通过对群众艺术馆整体结构进行受力计算，分析了该空间桁架体系的受力性能。分析表明，相互支承的水平及竖向平面桁架具有良好的空间受力性能，同时具有良好的稳定性；该空间桁架在各荷载作用下，构件均处于弹性阶段，满足设计要求。

Abstract:The spatial steel truss system at the southwest corner of Mass Art Center in Shandong Culture and Arts Center is composed of horizontal plane trusses with vertical plane trusses. The spatial trusses can be used as the effective support of large-span roof beams to transfer the vertical loads, to ensure the normal use of large-span roof. And the spatial trusses can also be used as the wind-resistant columns. When corner horizontal trusses were under the horizontal wind load, the horizontal trusses in two directions can support each other to transfer the horizontal loads to the lateral components of the main structure, and guarantee the stability of vertical trusses. Through the calculation of the overall structure of  Mass Art Center, the mechanical properties of the spatial truss system were analyzed. The analysis shows that the horizontal and vertical plane trusses that support each other have good spatial mechanical performance and good stability; under various loads, components of the spatial truss are in the elastic stage, which meets the design requirements.
