Note On Effect Of Elastic Deformation At The Root Of A Cantilever Beam, M.T. Liang, D.B. Chan
Note On Effect Of Elastic Deformation At The Root Of A Cantilever Beam, M.T. Liang, D.B. Chan
Journal of Marine Science and Technology
Parkes neglected elastic strains and examined a classical problem of rigid- plastic structural dynamics for finding the deformation of a cantilever beam carrying a mass at its tip which is subjected to a short pulse loading. Symonds and Fleming examined the Parkes problem by making comparison between exact numerical solutions obtained from an ABAQUS program for an elastic-plastic beam and the rigid-plastic solution slightly modified to allow for large deformation. Further observation is acquired by comparision also with a simplified elastic-plastic approach based on treatment of elastic and plastic action in artificially separated stages. and Yu examined the Parkes problem …
Engineering Properties And Application Of Cement-Based Fly Ash Blocks, R. Huang, J.J. Chang, W. Yeih
Engineering Properties And Application Of Cement-Based Fly Ash Blocks, R. Huang, J.J. Chang, W. Yeih
Journal of Marine Science and Technology
Under the consideration of environmental protection, direct disposal of coal ash is not acceptable. It is required to solidify fly ash before ocean disposal or land disposal. The objective of this study is to investigate the properties and the possible applications of the solid blocks produced from fly ash. Thirty-six mixes have been proportioned using different cementing materials such as portland cement, lime, sludge treatment compound, and industrial silica slag. Extensive laboratory studies have been conducted to evaluate the block properties such as compressive strength, tensile strength, abrasion resistance, and soundness. In addition, the possible engineering application is also evaluated. …

Simplified Procedure For Evaluating Soil Liquefaction Characteristics, Shuh-Gi Chern, Tain-Shyang Chang
Journal of Marine Science and Technology
The purpose of this paper is to develop a mathematical model for the evaluation of liquefaction characters for soil subjected to earthquake induced cyclic loading. Cyclic triaxial test results are used to develop the basic model. It is then used to evaluate cyclic shear strength τR, number of cycles required to cause liquefaction Nι or failure condition Nf , and the generation of excess pore water pressure Ug. The development of this model is a great breakthrough for the evaluation of liquefaction characteristics for soils under earthquake loadings.
