摘要
探讨超长预应力混凝土结构预应力后浇带常用设计方法,指出其不足之处。对允许出现限值裂缝的超长预应力混凝土结构提出非预应力后浇带设计方法,并通过理论分析和算例验证了此法的可行性。
Design methods currently dealing with prestressed post-poured strips of prestressed concrete structures with large longitudinal length are discussed and problems are put forward. A new method that designing post-poured strips by using only reinforcements is brought forward for prestressed concrete structures with large longitudinal length, for which finite crack width is permitted. The method is proved applicable through theoretical analysis and exemplificative verification, so it is worth consulting.
