摘要
结合某国际会展中心超长多跨连续预应力混凝土框架梁的设计,着重就预应力损失以及竖向构件侧向刚度对混凝土梁预应力效应的影响,对各种张拉方案进行了分析比较,以确定设计和施工方案。
This article combines the design of long-distance multi-span prestressed concrete frame beams of a certain International Conference & Exhibition Center,emphasizing the loss of prestress and the influence of concrete beam prestressing force effect by lateral rigidity of vertical member,analyses and compares various kinds of stretching plans, decides design and construction method.
