Also, in the test for compressive strength with drilled cores of cylindrical specimens, the concrete is lateral spreading, leading to Cracks in Concrete Structures rather than actual crushing. Hence, the purpose of this study is to evaluate the framework of the strength of concrete on the basis of failure modes of concrete’s lateral transformation. The study includes two sections, which are the analysis and the experiment. The section of analysis focus on the inquiry of cylindrical specimens of different size meet the maximum to ultimate stress with the finite element software ANSYS and 2D solid elements to simulate cylindrical specimens. The experiment has five specimens for monotonical compression test so that the measurement of lateral transformation can be achieved due to LVDT in the lateral middle of each specimen. With the comparison of experiment statistics and analysis data, the similarity between CNS1238’s length to diameter ration and the tendency of corrected intensity factor can be attained. To make experimental data correspond to the analysis, the parameter of analysis can be used with the experimental data. In this case, the result of this study can be proceed the statistical analysis and evaluate the application of fracture of concrete specimens of different materials. 林至聰 2010 學位論文 ; thesis 90 zh-TW |

碩士 === 國立臺北科技大學 === 土木與防災研究所 === 98 === The method of test for compressive strength of cylindrical specimens has been widely used on evaluating the strength of concrete.

Hence, the purpose of this study is to evaluate the framework of the strength of concrete on the basis of failure modes of concrete’s lateral transformation.
