自调节机敏混凝土的研究进展
|
摘要
自调节机敏混凝土可以在环境变化以及遭受自然灾害时,通过对结构变形、承载能力以及振动特性的调节,有效地提高建筑的适用性、安全性和使用效率。阐述了形状记忆合金、电流变体和碳纤维与混凝土复合的机敏特性,介绍了自调节机敏混凝土的研究现状。分析了这三种机敏材料在机理和材性研究方面存在的问题及发展方向。提出实现自调节机敏混凝土的工程应用必须实现机敏材料本身的高性能和多功能化,解决复合材料间的适应性、协调性和同寿命问题。
When the circumstance of self-regulating concrete changed or the self-regulating concrete suffered nature disaster,it can improve the applicability,security and availability factor of building through adjusting structure deformed,carrying capacity and vibration characteristic.The smart characteristics of shape memory alloy,electrorheological fluid and carbon fiber compound with concrete was expounded in the paper,it also introduced the status of smart concrete.Problems and development direction of these smart materials' mechanism and characteristics were analysed.The paper proposed:The preconditions of self-regulating smart concrete can be used in civil engineering were high-performance and multifunction of smart materials must be achieved,problems such as adaptability,coordination and the same longevity of materials in composite material must be solved.
