The mechanical properties of FRP fabric steel-reinforced concrete columns

摘要

The mechanical properties of FRP steel-reinforced concrete columns are discussed. We study the constitutive relation of the concrete, based on the model and the experimental dates for the control the size of affecting parameters. When using the used model, the experimental dates can be reanalyzed and corrected for the intensity correct formula of FRP column. The ultimate bearing capacities of FRP constraint rectangular column use superposition principle to calculate the strength calculation. The ultimate bearing capacity of FRP column is divided into two parts: we conclude the big eccentric bearing capacity calculators' formula by the column's bend. Through the study of the column, we concluded that the eccentric loading little eccentric calculation formula of bearing capacity. A case though using the example of this formula is similar with experiments results of the data.
