The Stress Performance Analysis Of Large Steel Reinforced Concrete Inclined Column’s Construction Process

Steel reinforced concrete columns have large bearing capacity, good seismicperformance, etc. And steel reinforced concrete columns have been widely used inlarge-span buildings and high-rise buildings. However, the construction process ofsteel reinforced concrete columns’ mechanical properties and safety performance hasnot been universal attention.The super oblique column which be studied in this paper is a59meters highcolumn which has a tilt angle of67.43degrees and a big section(1.8m×3.6m).Thecolumn construction is so difficult and so long to complete. Therefore,the mechanicalproperties and safety performance of column’s construction process is particularlyimportant.In order to analyze the relevant characteristics of SRC oblique column’sconstruction process effectively, this paper analyzes the pros and cons and the researchof SRC,then this paper analyzes the constitutive relation of steel and concrete. On thisbasis, this paper has established seven models in different conditions of SRC obliquecolumn according to Guiyang Huaguoyuan “NO.1” office building’s constructionprocess. And this paper analyzes the stress, strain and displacement of SRC obliquecolumn. This article concludes: stress, strain and displacement of SRC obliquecolumn’s construction phase are within specification and design requirements. It showsthat during the construction phase oblique column stress is safe, and the obliquecolumn has a large margin of safety. Because of difficulty and complexity, this papermakes a whole process real-time monitoring. The result shows that (1)SRC obliquecolumn’s stress is safe;(2)Concrete, steel, and longitudinal reinforcements of the SRCoblique are stress concentration;(3) In the complex loading conditions, steel reinforcedconcrete column has the trend of torsion, and steel flange oblique column cansufficiently improve internal force distribution by virtue of steel’s shape and strengthadvantage;(4) The horizontal displacement of the vertical component parts of buildinghas the rapid growth in height.According to the results of finite element analysis and of real-time monitoring, weshould check each section stress and calculate displacement of oblique column in theconstruction process of oblique SRC column. Then we control the constructionprocess, optimize oblique column’s internal stress and linearity based on the results, and ensure the safety of construction process.
