A simple formulation for effective flexural stiffness of circular reinforced concrete columns.
Engineering Applications of Artificial Intelligence(2015)
摘要
Concrete cracking reduces flexural and shear stiffness of reinforced concrete (RC) members. Therefore analyzing RC structures without considering the cracking effect may not represent actual behavior. Effective flexural stiffness resulting from concrete cracking depends on some important parameters such as confinement, axial load level, section dimensions and material properties of concrete and reinforcing steel.
