桥梁的大部分毛病是由于有缺点的细节设计所造成的。钢筋混凝土结构之细节设计有不少缺点是在钢筋变换方向及其终止处。例如图1所示对接节点可以看成如图示之力的三角形,因而绝对必要的要点是钢筋骨架的斜向钢筋要通过与外力的交点并要有足够的锚固。这种方式的细节结构从1963年起作者就已经应用。斜向钢筋是由细直径箍筋组成并锚固主筋 Most of the problems with bridges are due to flawed detail design. The details of the design of reinforced concrete structures have many disadvantages in the direction of the rebar and its termination. For example, the docking node shown in Figure 1 can be seen as a triangle of the force shown in the figure, so the absolutely necessary point is that the inclined steel bar should pass through the intersection with the external force and should have enough anchorage. The details of this approach have been applied by authors since 1963. Oblique rebar is composed of thin diameter stirrups and anchor the main reinforcement
