The Research Of Monitoring And Application On Beam Structure From The Large-span Steel Reinforced Concrete

With the improvement of the spiritual civilization and the construction technology in China, people’s all requirements for the architecture are not the using function, they will pay more attention to the distinctive modeling and special function. So, this will lead to very complex building structure and stress, and also will bring the more difficulties and other uncertain factors to the construction process. In order to ensure the safety in the construction process, the monitoring for structure during the construction in time is very effective and necessary.This paper relies on the Chang Jiang Crossing Campaign memorial project, and analyzes the large span steel reinforced concrete beam in the main structure’s inclined roof. First, this paper introduces the development and the research achievements about the steel reinforced concrete structure in the world. Then it summarizes the calculation theories about the steel reinforced concrete structure in our country, and calculates the35m steel reinforced concrete beam in Chang Jiang Crossing Campaign memorial main structure’s inclined roof. Second, the monitoring data during construction of Chang Jiang Crossing Campaign memorial are analyzed, the nonlinear method is used to get the fitting curve of stress-strain relation during construction, and the concrete constitutive relation of this project is acquired. Last, the steel reinforced concrete beam is analyzed by ANS YS, and stress-strain laws in construction process are obtained. The rich experience for the future similar projects are accumulated by comparing the simulation value to monitoring data.
