Abstract

This paper presents the results of a shear test on a reinforced concrete beam retrofitted with modularized steel plates. A total of five retrofitted concrete beams with various span-depth ratios as a variable were fabricated and tested. A companion beam without retrofitting was used as the control specimen. The results of this experiment confirmed that the method proposed in this study improved the shear performance by approximately 1.8 times compared with the non-retrofitted reinforced concrete beam. The test results indicate that the shear retrofitting method using modularized steel plates can be effective in retrofitting the concrete beams, resulting in improvement in the strength, stiffness and deformations.

摘要

本文介绍了对采用模块化钢板加固的钢筋混凝土梁进行抗剪试验的结果。共制作并测试了五根以不同跨高比为变量的加固混凝土梁。一根未加固的对比梁用作控制试件。本试验结果证实，与未加固的钢筋混凝土梁相比，本研究提出的方法将抗剪性能提高了约1.8倍。试验结果表明，采用模块化钢板的抗剪加固方法对混凝土梁进行加固是有效的，可提高梁的强度、刚度和变形性能。
