Finite element modeling of reinforced concrete shear wall subjected to static loading

Tóm tắt

This paper presents a numerical modeling of RC shear walls using SSI3D finite element program. The objective of this research is to develop the full-scale model lab test of reinforced concrete (RC) shear wall. The wall is subjected to axially and laterally monotonic loading up to failure. The concrete performance is represented by 20-node solid elements that have ability of modeling the cracking in tension and failure in compression. The main steel reinforcing bars and stirrup are modeled by nonlinear bar elements that only axial stress-strain behavior is considered. The analysis results show that the concrete reaches to failure states in both tension and compression while the rebars only yield in tension.
