Stress-strain curves of concrete confined by spiral reinforcement: Ahmad, S H and Shah, S PAm. Concrete Inst. J. Proceeding Volume 79 No 6 (November- December 1982) pp 484–490ELSEVIER《Computer-Aided Design》doi:10.1016/0010-4485(83)90166-5None...
concrete peak stress and strain under different strain rates and different specimen sizes are analyzed.Based on mathematical statistics theory,dynamic constitutive model of concrete is established by considering the size effect.The relationship between related parameters in constitutive model and strain rate...
• The equation proposed by Attard and Setunge for prediction of strain of concrete at peak compressive stress (ε c , %o) is compared with Arıoğlu's equation 33,34 (Eq. [A-6]) and it is found that the two are in close agreement with each other (Fig.B[a]). The equation...
Park, 3 Fellow, ASCE ABSTRACT: A stress‑strain model is developed for concrete subjected to uniaxial compressive loading and confined by transverse reinforcement. The concrete section may contain any general type of confining steel: either spiral or circular hoops; or rectangular hoops with or ...
