[摘要]山東省文化藝術中心群眾藝術館西南角的空間鋼桁架體系是由水平平面桁架與豎向平面桁架組成,該空間桁架可作為大跨度屋面梁的有效支撐,其傳遞豎向荷載,保證了大跨度屋面的正常使用;又可作為抗風柱,該轉(zhuǎn)角水平桁架受水平風荷載時,兩方向的水平桁架可以互相作為支撐將水平荷載傳遞給主體結構抗側力構件,同時又保證了豎向桁架的穩(wěn)定性。通過對群眾藝術館整體結構進行受力計算,分析了該空間桁架體系的受力性能。分析表明,相互支承的水平及豎向平面桁架具有良好的空間受力性能,同時具有良好的穩(wěn)定性;該空間桁架在各荷載作用下,構件均處于彈性階段,滿足設計要求。

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.
