Experimental Study On Shearing Resistance Of Srshc Short Columns

Reinforced super-high-strength concrete and steel reinforced super-high-strength concrete will being widely used with the development of the high-rise building. The research is carried out for the shear of mechanics performance of reinforced super-high-strength concrete and steel reinforced super-high-strength concrete short columns by the test of 24 short columns.Particularly introduce the performance of steel reinforced concrete columns. Set forth the appliance and development of steel reinforced concrete columns. Expatiate the shear force of steel reinforced concrete columns. Introduce the main work in the test of the reinforced super-high-strength concrete short columns and steel reinforced super-high-strength concrete short columns.Make the design of steel reinforced super-high-strength concrete short columns and super-high-strength concrete short columns. The main research focuses on the impact of nt, pv etc. to the shear strength of steel reinforced super-high-strength concrete columns. Introduce the load settings. In addition, analyze several guideline strength relationships of super-high-strength concrete.The test research of shear strength of reinforced super-high-strength concrete frame short columns is carried put in the paper. The main factors that affect the shear strength of reinforced super-high-strength concrete short columns are analyzed. The shear resistance formula of reinforced super-high-strength concrete short columns is put forward by the test. The calculated results are corresponding with the test results well.The shear resistance of reinforced super-high-strength concrete short columns is incresing with the accretion of nt, but the degree of accretion becomes smaller when nt reach a certain value. The shear strength of reinforced super-high-strength concrete short columns is higher along with the accretion of pv, but the degree of accretion is smaller when pv is bigger to a certain value.The test research of shear strength of steel reinforced super-high-strength concrete short columns is carried out. This thesis analyses the influnce of nt and pv on the shear strength. The main factors that affect the shearing resistance formular of steel reinforced super-high-strength concrete short columns is put forward, which based on the superposed strength method. The calculated results are corresponding with the test results very well.The shear strength of steel reinforced super-high-strength concrete short columns is increasing with the accretion of nt, but the degree of accretion is thinner when nt is bigger to a certainty value. The shear strength of steel reinforced super-high-strength concrete short columns is increscent along with the accretion of pv, but the degree of accretion is smaller when pv is bigger to a certainty value.
