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。
The space steel truss system in the southwest corner of the mass art center of Shandong Cultural and Art Center consists of a horizontal plane truss and a vertical plane truss, which can be used as an effective support for long-span roof beams. The space truss transmits vertical loads to ensure long-span Roof normal use; but also as a wind column, the horizontal angle of the horizontal truss by horizontal wind load, the horizontal direction of the two horizontal truss can be used as a support for the horizontal load transfer to the main structure of the anti-lateral force components, while ensuring the vertical truss Stability. By calculating the overall structure of the mass museum, the force performance of the space truss system is analyzed. The analysis shows that the horizontal and vertical plane trusses supporting each other have good space force performance and good stability. The members of the space truss are in elastic stage under each load and meet the design requirements.
