Study on Bearing Capacity of Reinforced Concrete Columns Strengthened by Adding Wing Walls

Article Preview

Abstract:

Wenchuan Earthquake has caused substantial damage to reinforced concrete columns, in order to improve their lateral stiffness, wing walls are added to repair and strengthen the columns. Based on engineering practice, the mechanical calculations of normal section bearing capacity on damaged reinforced concrete columns strengthened by wing walls have been conducted, and based on the N-M curves of various special-shaped columns, the influence laws of different azimuths and different axial compression ratios on bearing capacity of normal section have been analyzed, therefore mechanical properties of special-shaped sections have been obtained, which provides reference information for engineering technology.
