Longzheng Bridge Construction Drawing Design
ABSTRACT
The construction scale of bridge projects is gradually expanding, which plays a vital role in China#39;s transportation industry.This design will design a prestressed concrete simply-supported T-beam bridge according to the design mandate and the latest national code.The bridge is named Longzheng Bridge with a span of 25m and a deck width of 11.25m. This article will first introduce the development and characteristics of prestressed concrete simply supported T-beam bridges in China.After reviewing and collating relevant literature at home and abroad and my preliminary understanding of bridge design, I will briefly explain the reason why I chose simply supported beams and T-sections. I will also introduce the main design content and the main points of the steps.Finally, combining the engineering software used in this design and my own situation, I will briefly describe how the software works in this design, and introduce my basic knowledge of engineering software.
Key words：Prestressed concrete; simply supported beam bridge; design content; engineering software
