答案：【计分规则】: Answer: In prestressed concrete structures, the existence of non-prestressed reinforcement is beneficial to the loss of prestress and anti-crack parts. The shrinkage and creep of concrete can be reduced due to the presence of non-prestressed reinforcement, that is, the loss of prestress can be reduced. At the same time, the presence of non-prestressed reinforcement can keep the concrete in compression zone away from being pulled apart due to excessive tensile stress during construction.
