Step 3 write results table. Using excel software output results to sort and draw graphics, then make it into word document printed.
Through the above steps, and strictly obey the traffic law about this kind of bridge design specification requirements, design a qualified bridge. Key words: concrete-filled steel tube arch bridge cable line; Multi-span continuous ChanXiangBan; Rigid beam method; Dr Bridge computer
第二步要对进行计算和验算。计算部分包括手算和电算，手算部分主要确定构件的内 力并对其配筋，采用多跨连续单向板计算桥面板内力，并通过配筋验算；采用了刚性横梁 法计算横梁及纵梁的内力，并且通过配筋验算。电算部分主要是为构件的验算服务；验算 部分主要包括建模正确性验算及全桥安全性验算。本部最为关键的便是建模，最后的计算 是否正确，在很大程度上取决于模型建的是否正确。本设计利用桥梁博士软件计算，定义 好截面尺寸、节点及单元。并将计算好的模型参数赋给模型结构单元。添加约束，输入荷 载后模型就建立完成，进入计算阶段。利用软件就可计算出结构各控制截面的内力。
The second step of calculation and checking. Calculate calculate part includes hand and computer calculation, hand part of the main component of the internal force and the reinforcement is determined, the bridge are calculated by use of a multi span continuous ChanXiangBan panel internal force, and through the reinforcement calculation; Adopted a rigid beam method to calculate the internal force of the beam and the longitudinal beam, and through the reinforcement calculation. Computer parts mainly for calculating the component services; Checking part mainly includes the modeling accuracy checking and the safety of the whole bridge calculation. Based modeling, the most important thing is the final calculation is correct, to a large extent depends on the built model is correct. This design USES a bridge software calculation, Dr Defined section size, node, and the unit. And will calculate a good model parameter is assigned to model structure unit. Adding constraints, input load model is built after the completion, entered into the phase of computing. Using the software can calculate the structure internal force of the control section.

跨径 160m 中承式钢管混凝土悬索线拱桥
摘要
本设计根据任务书要求设计一跨径 160m 中承式钢管混凝土悬索线拱桥，矢跨比为 1/5， 拱轴截面采用等截面。
第一步进行初步设计。即拟定所选方案桥型的具体尺寸以及相关参数。根据含钢率、 套箍指标及设计经验等拟定拱肋截面；根据承载力及配筋要求确定桥面板、纵梁、横梁尺 寸；根据一般设计经验确定横撑、吊杆、立柱尺寸；根据已有资料确定拱轴线方程。
Abstract
This design according to the requirements specification design a span of 160 m half-through arch bridge concrete suspension cable line, rise-span ratio of 1/5, cross section in cross section of arch axis, etc. The first step for preliminary design.
