环形预应力混凝土叉梁的设计与研究

Design And Research For The Circular Prestressed Concrete Cross-Bracing

本文介绍新研制的环形预应力混凝土叉梁的设计与试验情况,并进行了结果分析,这种叉梁受力不受方向性限制,外形美观,运输方便,刚度大,抗裂性好,节省钢材,造价低,可在工程中推广使用.

The paper introduces the recent progresses of newly developed prstressed concrete bracing. With the advantages of good shape, better resistance to crack, easy to transport, better rigid deforma-bility, lower price and steel consumption fhe analysis of the results show that the bracing is not restrained on directions and can be widely used in transmission projects.
