【期刊论文】On the buckling failure of a pressure vessel with a conical end
赵阳

-1年11月30日
In this paper, the most up-to-date research on the buckling of internally-pressurized cone±cylinder intersections and state-of-the-art ®nite element analyses are deployed to provide another anatomy of a pressure vessel failure due to mis-operation overpressure recently reported and analyzed by Jones [Jones, DRH. Buckling failures of pressurized vessels: two case studies. Engineering Failure Analysis 1994;1:155±67]. Existing research on these intersections is ®rst outlined, followed by a description of the buckling strength formulae recently developed to approximate ®nite element buckling loads of the perfect geometry. The validity of these formulae for real vessels with geometric imperfections is next examined through a comparison of theoretical predictions with experimental results, which establishes the limited sensitivity of the buckling load to initial imperfections. The buckling pressure of the cone±cylinder intersection in the failed vessel is then determined using these formulae, while the buckling pressure of the spherical partition in the vessel is evaluated using the ECCS rule. These calculations demonstrate that the cone±cylinder intersection buckled ®rst, followed by the buckling of the spherical partition, which also released the vessel from overpressure. The buckling pressure of the spherical partition is therefore also the maximum pressure exerted on the vessel. This proposition is con®rmed by postbuckling analyses of the vessel.

【期刊论文】Buckling experiments on steel silo transition junctions I: Experimental results
赵阳, Y. Zhaoa, J.G. Tengb, *

Large elevated steel silos for the storage of bulk solids generally consist of a cylindrical vessel above a conical discharge hopper supported on a cylindrical skirt. The cone-cylinder-skirt transition junction is subject to a large circumferential compressive force which is derived from the horizontal component of the meridional tension in the conical hopper, so either a ring is provided or the shell walls are locally thickened to strengthen the junction. Extensive theoretical studies have examined the buckling and collapse strengths of these junctions, leading to theoretically based design proposals. However, no previous experimental study on steel silo transition junctions has been reported due to the considerable difficulties associated with testing these thin-shell junctions at model scale. This paper presents the results of a series of tests on cone-cylinder-skirt-ring junctions in steel silos under simulated bulk solid loading. In addition to the presentation of test results including geometric imperfections and failure behavior, the determination of buckling modes and loads based on displacement measurements is examined in detail.

简仓结构广泛应用于农业、矿业、化工、电力等诸多领域中的散料储存。混凝上筒仓在国内已有许多应用,但钢筒仓的应用还很有限。过去二十年里国际上对钢简仓结构的性能致强度进行了大量的研究,香港理工大学在近几年也进行了许多研究。本文总结了大型圆形钢筒仓结构行为及设计方面的近期研究进展。首先对钢筒仓的结构形式及散料荷载进行简单讨论,并介绍钢筒仓的主要破坏形式发相应的研究,给出了可供钢筒仓结构设计直接应用的部分主要设计公式。还介绍了钢筒仓结构设计中的计算机分析方法,最后指出钢筒仓结构尚需进一步研究的课题。

【期刊论文】Techniques for buckling experiments on steel silo transition junctions
赵阳, J.G. Teng*, Y. Zhao, L. Lam
Thin-Walled Structures 39(2001)685-707,-0001,():
-1年11月30日
Large elevated steel silos generally consist of a cylindrical vessel, a conical discharge hopper and a skirt which may either be supported on the ground or by a number of columns. The cone-cylinder-skirt junction is subject to a large circumferential compressive force due to the radial component of the meridional tension in the hopper, so either a ring is provided or the shell walls are locally thickened to strengthen the junction. Many theoretical studies have examined the buckling and collapse strengths of these junctions, but no previous experimental study has been reported. This has been due to the great difficulties associated with testing these thin-shell junctions at model scale. This paper first describes the development of an experimental facility for testing model steel silo transition junctions. Issues covered include the fabrication of quality model junctions using thin steel sheets, the loading method and the precise three-dimensional measurement of geometric imperfections and deformed shapes using a laser-displacement meter. Typical experimental results of a cone-cylinder-skirt-ring junction are next presented to demonstrate the capability of the developed facility. Procedures for processing the test results to determine both the buckling load and the number of buckling waves are also presented.

建造在软土地基上的大型储罐会产生各种沉降变形,其中罐周不均匀沉降对结构的影响最为不利本文首先对软土地基上大型储罐沉降的主要类型和特点做简要总结,然后分析罐周不均匀沉降对不同类型钢储罐结构(浮顶罐和固定顶罐)的影响,并回顾了不均匀沉降下钢储罐结构应力分析的有关研究文中还指出,目前由岩土工程师凭借经验提出的储罐地基变形允许值从结构工程的角度看不尽合理,合理的取值应充分考虑储罐结构对地基变形的响应

【期刊论文】A stability design proposal for cone–cylinder intersections under internal pressure
赵阳, Y. Zhaoa, J.G. Tengb, *
International Journal of Pressure Vessels and Piping 80(2003)297-309,-0001,():
-1年11月30日
Cone-cylinder intersections are used commonly in pressure vessels and piping, and internal pressurization is often an important loading condition. For the intersection of the large end of a cone and a cylinder, internal pressurization causes large circumferential compressive stresses in the intersection. These stresses can lead to failure of the intersection by either axisymmetric collapse or non-symmetric buckling. This paper first presents a brief summary of recent experiments on cone-cylinder intersections under internal pressure.Arational finite element model based on the experimental and the corresponding numerical results is next described. Finite element results from a major parametric study on the postbuckling behaviour and strength of cone-cylinder intersections employing this finite element model are then presented. Finally, a design proposal in the Eurocode format for internally pressurized cone-cylinder intersections is established for practical use.

【期刊论文】Distortional buckling of channel beam-columns
赵阳, J.G. Tenga, ∗, J. Yaoa, Y. Zhaob

Cold-formed lipped channel sections have been widely used in light gauge steel construction. Among the several possible buckling modes, the distortional buckling mode involving rotational deformation of the flange–lip combination about the flange–web junction is often the strength-governing mode. While many studies have been carried out on this buckling mode, the method of Lau and Hancock (J. Struct. Eng. ASCE 113 (1987) 1063), which models the phenomenon as the flexural–torsional buckling of the flange–lip combination with elastic restraints from the web appears to be the most effective in producing a relatively simple closedform solution for design use. This article extends the Lau and Hancock method, which was developed for axially loaded columns to beam-columns subjected to combined axial compression and biaxial bending. Particular attention is paid to the case of axial compression in combination with uniaxial bending in the plane of symmetry. Numerical results from the present closed-form solution are compared with those from the finite strip method, showing a close agreement between the two. The numerical results also lead to a number of useful observations on the distortional buckling behavior of these beam-columns, which should be useful in the future development of a simplified solution for direct design use.

当前空间结构的发展方兴未艾、极具活力,新的空间结构形式不断涌现,传统的空间结构分类方法有时难以适应新的发展要求。本文提出一种以空间结构组成的基本单元进行分类的新的空间结构分类方法。组成空间结构的基本单元可归纳为板壳单元、梁单元、杆单元、索单元和膜单元等五种。根据国内外已建的空间结构工程,总结了33种具体的空间结构形式,它们均可由某一种单元或某两种、三种单元构成。文中还结合近年来空间结构发展中出现的一些新结构,对新的分类方法作了说明与讨论。

对一组圆柱面网壳交叉组合形成的新型网壳结构——叉筒网壳中的单层脊线式叉筒网壳的结构性能进行了系统研究。运用有限元方法分析了该结构在对称与非对称荷载作用下的静力性能,并着重讨论了矢跨比、荷载工况、边界条件和几何初始缺陷对结构非线性稳定性能的影响。研究了不同矢跨比和不同屋面荷载作用下的结构自振特性,并比较了不同矢跨比结构在地震作用下的水平地震内力和竖向地震内力。研究结果表明,单层脊线式叉筒网壳受力性能良好,非对称荷载对结构性能的影响不大;矢跨比对结构的稳定极限荷载和动力性能影响较大;随几何初始缺陷的增大,结构稳定极限荷载平缓降低。
