项目摘要

The objective of the study is to develop practical methods of evaluation the ultimate strength and deformability of reinforced columns with wing walls. A series of tests on half-scale specimens representing the column members with wing walls have been conducted from 2007 to 2010 to verify the evaluation methods. Shear tests were conducted in the first three years, by which the ultimate shear strengths of the members were identified. The measured shear strengths were compared with the calculated strengths based on the conventional design formula as well as the new formula proposed by the authors, by which a better correlation was observed with the test results of the first series. Flexural tests were conducted for six specimens in 2010 to investigate the design details on the ultimate flexural deformability. The ultimate deformations are compared with the calculation using the proposed design form practice, by which fair correlations are obtained. Axial shear flexure interaction model was also applied to the specimens, by which the load deformation relations including the strength decay were correlated with more accuracy to the test results.

该研究的目的是开发评估带翼墙的钢筋柱的极限强度和变形能力的实用方法。 2007年至2010年，对带有翼墙的柱杆半比例试件进行了一系列试验，以验证评估方法。前三年进行了剪切试验，确定了构件的极限剪切强度。将实测抗剪强度与基于常规设计公式以及作者提出的新公式计算的强度进行了比较，发现与第一系列的试验结果有更好的相关性。 2010年对六个样本进行了弯曲试验，以研究极限弯曲变形能力的设计细节。将最终变形与使用所提出的设计形式实践的计算进行比较，从而获得公平的相关性。轴向剪切弯曲相互作用模型也应用于样本，通过该模型，包括强度衰减的载荷变形关系与测试结果更准确地相关。
