| Abstract: | The constructing procedure of the monolithic layer and the wet joints of the girders and the orders of straining the pre-stress force are the key orders of the simply supported-continuous system.This paper studied the orders of the monolithic layer and the wet joints of the girders with practical project.And also it established limited element model to analysis the order of the wet joints of the girders and straining pre-stress force to the structure.Through the contrasting analysis,we can achieve an elemen... |
