本文打算强调指出直接影响到桥梁施工的若干设计问题。虽然讨论主要是针对北美的施工人员,但许多概念可以有效地用于世界各地。着重讨论五个主要方面: 1.非预应力钢筋——讨论使用非预应力钢筋对控制结构的性能和对节段式混凝土桥梁在不同施工阶段加强构件强度的必要性及适应性。 2.挠度的控制——叙述在节段式桥梁中铰的位置和附加补充力筋对控制挠度所起的作用。
This article intends to highlight a number of design issues that directly affect bridge construction. Although the discussion is primarily aimed at North American builders, many of the concepts can be effectively used around the world. Five main aspects are highlighted: 1. Non-prestressed bars - The necessity and suitability of non-prestressed bars to control structures and to reinforce component strength at different stages of construction are discussed. 2. DEFLECTION CONTROL - Describe the effect of the position of the hinges in the segmented bridge and the additional supplemental tendons on the control of deflection.
