摘要
基于ABAQUS中的损伤塑性模型建立了带填充墙RC框架的有限元模型,并通过与试验结果对比验证了有限元模型的可靠性。基于此,建立了典型材料强度下的带填充墙RC框架模型,研究了填充墙平面内损伤对平面外承载力的影响,评价了不同损伤状态下ECC平面外加固效果。结果表明:平面内损伤会影响平面外承载力,平面外承载力与层间位移比呈负相关关系;相较于其他损伤状态,在墙体未损伤以及轻微损伤时,采用ECC单面加固效果更加明显,可为工程加固提供科学依据。
Based on the damage-plastic model of ABAQUS,the finite element model of RC frame with filled walls was established, and the reliability of the finite element model was verified by comparing with the experimental results.Based on this, the RC frame model with filled wall under typical material strength was established to study the influence of in-plane damage of filled wall on out-of-plane bearing capacity and evaluate the out-of-plane reinforcement effect of ECC under different damage states.The results show that the in-plane damage affects the out-of-plane bearing capacity, and the out-of-plane bearing capacity is negatively correlated with the interlayer displacement ratio.Compared with other damage states, the single-side reinforcement effect of ECC is better when the wall is not damaged or slightly damaged, which can provide a scientific basis for engineering reinforcement.
