Analysis of Massive Platform Concerte 3-Dimensional Hydration Heat of Corrugated Steel Webs Bridge

Abstract:

with the continuous development of bridge engineering，the massive concrete has been widely used in large-scale bridge foundation engineering. But it often has the problems of crack and deformation, which infuenced the entirety and durability of the whole structure seriously. In this paper, a hydration heat analysis of the platform of a corrugated steel webs bridge is carried out by using MIDAS/Civil structure finite element method analysis program, the analysis summarizes the temperature distribution regulation of platform concrete influenced by hydration heat and the temperature changing regulation affected by time. Meanwhile, some countermeasures of preventing the crack of concrete are put forward.
