Abstract

An analytical method to calculate the time dependent stresses and strains in RC columns is presented. Linear viscoelastic models are used to simulate the time dependent behavior of both plain and reinforced concrete. Both concentrically and eccentrically loaded columns are considered. The experimental results are used to obtain the parameters of the model, namely the spring constants and viscosity coefficients, For the concentrically loaded column, the proposed method is compared with the available experimental results. The model predictions are reasonably accurate, A flow chart presents the sequence of operations for the time dependent analysis of concentrically loaded columns. Numerical examples are also presented to further clarify the calculation procedures.
