摘　　要：为研究新型再生柔性连接的力学性能,探究新型再生柔性连接材料应用于现浇填充墙框架结构的平面外性能影响,通过调整配方中DOA、TAR和DMA的比例,配制了三种不同性能的再生橡胶材料,设计制备了混凝土新型再生柔性连接组合试件并进行剪切性能试验研究。试验表明,再生橡胶材料具有较好的力学性能,将其应用于现浇填充墙框架结构中能很好地限制墙体平面外变形。根据等效侧力法及填充墙平面外损伤指标评估得出,将新型再生柔性连接应用于现浇填充墙框架结构中,在等效罕遇地震作用力的情况下,墙体仍处于完好状态。新型再生柔性连接与混凝土之间具有较强的咬合力,能最大限度地发挥新型再生柔性连接材料的力学性能。To study the mechanical properties of the new recycled flexible joint materials and investigate the impact of out-of-plane performance of the new recycled flexible joint materials applied to cast-in-place infill wall frame structures,three recycled materials with different properties were prepared by adjusting the ratio of DOA,TAR and DMA in the formula,and the new recycled flexible joint combination specimens of concrete were designed and tested for shear performance research.The results showed that the regenerated rubber material has good mechanical properties,and its application to the cast-in-place infill wall frame structure can well limit the out-of-plane deformation of the wall.According to the equivalent side force method and the infill wall out-of-plane damage index assessment,the new regenerated flexible connection was applied to the cast-in-place infill wall frame structure,and the wall was still in an intact state in the case of an equivalent rare-earthquake force.The new recycled flexible connection has a strong occlusal force between the concrete,which can maximize the mechanical properties of the new recycled flexible connection material.
