Twenty-seven large-scale beams with dapped-end have been prepared, cast and tested to failure in the three points loading arrangement. One control beam has been designed in accordance with requirement of standard code while the dapped-end reinforcement scheme of other beams has been derived from the control beam. In selected beams, engineered cementitious composites (ECC) has been utilized in the dapped-end region. The test results exhibited that DR is more appropriate and higher capacity than HR in resisting the shear force. In addition, the reinforced engineered cementitious composites dapped-end beams (R-ECC-DEB) showed higher structural performance compared to the normal reinforced concrete dapped-end beams (RC-DEBs). The strength of ECC also has direct effect on the failure capacity of the R-ECC-DEB, in which higher strength of ECC leads to higher failure capacity of R-ECC-DEB.

基于ECC结合的吊架或对角钢筋作用的RC和R-ECC Dapped-end梁的结构性能

在三点加载布置中，已准备、铸造和测试了 27 根大型端部钝化梁。一根控制梁按照标准规范的要求进行设计，其他梁的端部配筋方案来源于控制梁。在选定的梁中，工程水泥基复合材料 (ECC) 已用于短端区域。试验结果表明，在抗剪力方面，DR 比 HR 更合适，具有更高的能力。此外，与普通钢筋混凝土短端梁（RC-DEB）相比，增强工程水泥基复合材料短端梁（R-ECC-DEB）显示出更高的结构性能。ECC 的强度也对 R-ECC-DEB 的失效能力有直接影响，
