Study on Strength and Stiffness of Special-Shaped SRC Columns
SRC (Steel Reinforced Concrete) columns have a very broad application in the construction industry, and their cross-section combined forms are becoming more and more diverse. To solve the strength and stiffness problem of special-shaped SRC columns fast and accurately, the formulas of bending stress and bending deflection of special-shaped SRC columns were derived based on plane assumption from the bending experiments of SRC columns. For the problem with a eccentric force, the formula of normal stress from axial force was derived and added to the bending stress. Based on the formulas, the program is implemented to calculate the bending stress and bending deflection of special-shaped SRC columns. The example results showed the formulas are simple and reliable, and have certain engineering meanings and theoretical value.
