| Abstract: | With the exhibition project of the Yangling Tombs of the Han Dynasty in the background,this paper brings forward the design and calculaton of prestressed concrete T beams with high load and low high-span ratio,combined with a great deal of domestic research datum and production. At the same time,the paper compares and analyzes the result of prestressed concrete beams with different high-span ratios and draws the correlative conclusion. It indicates that this improved calculated way has much predominance with high accuracy, conveniet uses. So it can be used to design engineering that requires high-calculated accuracy, and be referenced by for similar engineering. |
