Modeling of tension stiffening in reinforced cement composites: Part II. Simulations versus experimental results

This is the second part of a two-part paper involving a numerical model for simulations of tensile behaviour of reinforced cement-based composites. The model simulates the tensile stress strain response of a brittle matrix composite, tension stiffening effect of cracked matrix, and crack spacing evolution in tension members. The paper presents the simulations of four independent experimental results obtained from literature: steel reinforced concrete, concrete reinforced with steel and glass fiber reinforced plastic (GFRP), alkali resistant (AR) glass textile reinforced concrete and AR glass fabric reinforced cement pastes. The first and third experiments had complete input information for the simulations, and the predicted responses compare quite well to the experimental results. The second and last experiments did not have complete input data but, the properties can be estimated from other sources or by means of back calculations. The predicted responses reasonably agreed with the experimental results.
