K8型网壳结构模型稳定矢跨比试验与应用探讨

Experiment and Application of Stable Sagittal Span Ratio of K8 Reticulated Shell Structure Model

伴随着建筑审美的不断发展,具有造型丰富、空间跨度大等诸多优势的网壳结构成为了应用最为广泛的空间结构之一。提升网壳结构的稳定性是当前研究的热点,且针对网壳结构杆件缺陷研究较为少见的情况,基于此,通过探索不同矢跨比对杆件屈曲K8型单层球面网壳结构稳定性所产生的影响从而优选最佳矢跨比。研究结果显示,在地震荷载作用下不同的矢跨比对网壳结构稳定性造成的影响是有明显差异的,矢跨比为0.4时K8型单层球面网壳结构的稳定性最好。

With development of architectural aesthetics,reticulated shell structure with many advantages such as rich modeling and large space span has become one of the most widely used spatial structures.Improving the stability of reticulated shell structure is a hot research topic at present,and it is rare to study the defects of reticulated shell structure.Based on this,the optimal sagittal span ratio is optimized by exploring the influence of different sagittal span ratios on the structural stability of the single layer spherical reticulated shell of buckling K8 type.The results show that the influence of different sagittal span ratio on the stability of reticulated shells under seismic load is obviously different,and the stability of K8 single-layer spherical reticulated shells is the best when the sagittal span ratio is 0.4.
