This design is the design on the structure of Ningbo City, Liyuan Garden of Hope Bridge.Engineering geological data and engineering practice, three different bridge solutions, compare and choose: reinforced concrete T-shaped simply supported beam bridge. 2. Reinforced concrete hollow slab bridge (single span) .3. Reinforced concretehollow Slab (double cross). To determine the bridge type for the recommended program in line with the the horoscopes principle of "security, economic, aesthetic, and practical", as well as T-shaped, reinforced concrete simply supported beam bridge advantages. The design of the bridge span 12m, T-shaped cross-section is 6m wide bridge, divided into two lanes.The design process, calculate the ultimate bearing capacity of the load combination of longitudinal reinforcement bent reinforced, and the arrangement of stirrups according to the specification, and finally bent reinforcing bars review, the width of crack, the main beam deformation checking, learned through access to specification checking to meet the specification. Using Midas software in order to improve design efficiency and accuracy of the design calculation, and take advantage of the CAD, Word and other office software to organize the design documents.

欧拉梁，直观来说即欧拉﹣伯努力栋梁方程，与简支梁的主要区别如下：
一、性质不同
1、欧拉﹣伯努力栋梁方程：欧拉-伯努利梁方程（英语：Euler–Bernoulli beam theory），是一个关于工程力学、经典梁力学的重要方程。
2、简支梁：指梁的两端搁置在支座上，支座仅约束梁的垂直位移，梁端可自由转动。
二、作用不同
1、欧拉﹣伯努力栋梁方程：是一个简化线性弹性理论用于用于计算梁受力和变形特征。
2、简支梁：两端支座仅提供竖向约束，而不提供转角约束的支撑结构。简支梁仅在两端受铰支座约束，主要承受正弯矩，一般为静定结构。
三、特点不同
1、欧拉﹣伯努力栋梁方程：欧拉-伯努利梁方程约形成于1750年，但这条方程却没有在后期建筑之中得到广泛的应用。直到十九世纪，这条方程才成为第二次工业革命的基石。
2、简支梁：简支梁只是梁的简化模型的一种，还有悬臂梁；悬臂梁为一端固定约束，另一端无约束；将简支梁体加长并越过支点就成为外伸梁；简支梁的支座的铰接可能是固定铰支座、滑动铰支座的。

This design is mainly about Ningbo City Lai Yuen Hing Bridge upper structure design. According to the engineering geological data and actual, put forward three kinds of different bridge type scheme comparison and selection:1T shaped reinforced concrete simply supported beam bridge of reinforced concrete hollow slab bridge,2( single ),3( double span reinforced concrete hollow slab bridge ). The spirit of "safe, economy, beautiful, practical" eight-character principle, as well as reinforced concrete T beam bridge the advantages, determined that the bridge for the recommended scheme.The design of the bridge span is 12M, with T shaped cross section, bridge deck width of 6m, divided into2 lanes.In the design process, through the ultimate bearing capacity load combination to calculate longitudinal steel bar, curved steel, and according to the standard layout of stirrups, the bending of reinforced position checking, checking the crack width, beam deformation checking, by referring to the standard that checking to meet the specification. In order to improve the design efficiency and accuracy, is adopted in the design of Midas software for calculation, and make full use of the CAD, WORD and other office software to organize the design document.
