缓粘结预应力研究现状

Research status of retarded bond prestress

缓粘结预应力技术是在克服有粘结和无粘结预应力的缺点,并继承其优点的基础上发展起来的一项预应力技术。缓粘结预应力技术是在有粘结和无粘结之后发展起来的一种新的预应力技术[1],具有无粘结预应力技术施工方便、造价低和有粘结预应力技术结构延性好、抗震性能优等特点。介绍了缓粘结预应力的技术特点及我国目前研究现状。

Slow-bonded prestressing technology is a prestressing technology developed on the basis of overcoming the shortcomings of bonded and unbonded prestressing and inheriting its advantages.Delayed bonding prestressing technology is a new prestressing technology developed after bonding and non-bonding[1].It has the advantages of convenient construction,low cost and bonding prestressing technical structureGood ductility and excellent seismic performance.The technical characteristics of retarded bond prestress and the current research status in our country are introduced.
