MOMENT CURVATURE ANALYSIS • Reinforced concrete design calculations normally assume a simple material model for the concrete and reinforcement to determine the moment capacity of a section. The Whitney stress block for concrete along with an elasto-plastic reinforcing steel behavior is the most widely used material model in American codes.
Non Linear Finite Element Analysis of Steel Fibre Reinforced Concrete Beams Jigna Jagadish . M.Tech student, department of Civil Engineering. Vimal Jyothi Engineering College. Kannur, Kerala, India. Abstract-The plain concrete normally contains numerous micro and macro cracks and it will begin to propagate in the matrix when load is applied.
Initially, linear stress and deformation analysis is carried out with three posts different in constitution. However, considering the role of periodontal ligaments, which ensures uniform stress distribution in tooth structure, due to its elastic and non-linear properties, it is felt necessary to simulate the model for non linear analysis.
