钢筋混凝土空间网格结构包括平板型的空腹网架结构、空腹夹层板结构、空腹双重网格结构、现浇混凝土空心大板楼盖结构。这些新型结构体系从20世纪80年代至今在跨度18~32 m公共建筑的屋盖和楼盖应用达100多万平方米,取得很好的社会与经济效益。有的已编制了相应的技术规程。我们研制了将钢筋混凝土空腹夹层板单向弯曲形成的钢筋混凝土空腹夹层网壳和网拱结构,双向弯曲形成的钢筋混凝土空腹夹层双曲扁网壳结构。这些拥有我国自主知识产权的空间网格结构新体系,均具有自身的特点和对建筑物的适应性,文章将按研制时间先后逐一介绍。其结构的“安全、合理、经济、先进”性,则通过工程实例予以剖析。

在本研究中,我们设计、制备和测试了两种新型折叠夹层圆柱壳。格栅夹芯具有周期性的“之”字形波纹,其脊线与谷线沿着轴向或环向延伸。通过自由振动和轴向压缩试验,我们研究了圆柱壳的固有频率、自由振动模态、承载能力和失效模式。通过减小局部蒙皮周期单元的尺寸,折叠格栅夹芯能有效地抑制折叠夹层圆柱壳的局部屈曲;通过提高夹层的剪切刚度,折叠格栅夹芯能有效地提高折叠夹层圆柱壳整体的抗屈曲性能。圆柱壳在材料失效模式下失效,其具有良好的承载能力。轴向折叠夹层圆柱壳具有更高的承载能力,而环向折叠夹层圆柱壳具有更高的固有频率。这两种折叠格栅内芯为工程师设计有强度或振动要求的夹层圆柱壳提供了一种选择。本研究也为大尺寸折叠结构的制作和工程应用提供了一种可行的方法。

最大弯曲正应力是衡量夹层梁弯曲性能的重要参数之一,本文推导出了将软夹芯夹层梁等效成等 截面均质单层梁计算最大弯曲正应力的方法,并在此基础上进行三点弯曲试验的算例研究。结果表明:修正单层梁理论与层合梁理论计算的结果是一致的。当破坏载荷与夹层梁横截面的尺寸一定时,随着芯层与总厚度比的增加,修正单层梁理论计算的最大正应力值逐渐增加,而单层梁理论计算的结果为一恒定值。最大弯曲正应力修正公式的建立为夹层梁的工程应用提供理论基础。

Hierarchical fractal structure of perfect single-layer graphene

The atomic lattice structure of perfect single-layer graphene that can actually be regarded as a kind of hierarchical fractal structure from the perspective of fractal geometry was studied for the first time. Three novel and special discoveries on hierarchical fractal structure and sets were unveiled upon examination of the regular crystal lattices of the single-layer graphene. The interior fractal-type structure was discovered to be the fifth space-filling curve from physical realm. Two efficient methods for calculating the fractal dimension of this fresh member was also provided. The outer boundary curve had a fractal dimension equal to one, and a multi-fractal structure from a naturally existing material was found for the first time. A series of strict self-similar hexagons comprised a rotating fractal set. These hexagons slewed at a constant counterclockwise angle of 19.1° when observed from one level to the next higher level. From the perspective of fractal geometry, these pioneering discoveries added three new members to the existing regular fractal structures and sets. A fundamental example of a multi-fractal structure was also presented.
