Dear teachers, good morning!

I am XXX of civil engineering XXX class. My graduation project topic is liucheng prestressed concrete box girder bridge design. This graduation design is in zhang wenkai completed under the guidance of the teacher, first of all, I am here to seriously strict teacher zhang said sincere respect and appreciation, also to sit xin-zhong wang, wang teacher, Zhou Shuming teacher, etc. All the teacher tireless teachings in four years, and today to take part in my thesis to express our heartfelt thanks to you for. Next, I will report the main contents of this thesis to your teachers, and I would like to ask your teachers for their criticism and guidance.

According to the research of box beam section of prestressed concrete continuous girder bridge, especially suitable for continuous box girder bridge in its structure, construction and use less seams, beam is high, stiffness big, strong integrity, good appearance, easy to maintenance etc, and prestressed continuous composite box girder bridge is widely used in recent years, so I feel my thesis topic is meaningful. In this design, more bridge design specifications are used. In addition to the general specifications for the design of some Bridges borrowed from the library, I have also checked the data through Internet resources such as civil engineering network and baidu wenku.

This design for me is a brand-new design, first contact with the design of the prestressed prestressed continuous box girder bridge, and is a computer model, bridge upper structure are all made of Dr Bridge calculation, using cad drawings, not only make us more skilled use of some bridge design software and the use of drawing software, also learned how to analysis and calculation results and data output.

Good morning, ladies and gentlemen. My name is XXX, and I am a student of the class xx night major civil engineering class. My thesis topic is the structure design drawing of a school building. Thesis is completed under the teacher of meticulous guidance, here I am deepest thanks to my teacher, also to all the teacher painstakingly to express my heartfelt gratitude for my dissertation, and on this for more than two years I have a chance to listen to the teachings, teachers expressed sincere respect. Next, I will report the purpose and main content of the design of this thesis, and I would like to ask your teachers for criticism and guidance. 　　First I want to talk about the structure and main content of this paper. 　　
This paper is divided into two parts:

The second part is the design of the structure drawing. This part analyzes the specific data and algorithm of reinforcement.

Finally, I want to talk about this paper and its shortcomings. Because of oneself learn xx professional background, and work at work, so in theory and practice in civil engineering appears grossly inadequate, although I collect materials as much as possible, doing everything they can to use their learned knowledge for thesis writing, there are still many shortcomings, but the paper needs to be improved. Please give me more criticism, let me learn more in the future.

That's all for my presentation, thank you! Please ask your teachers questions.
