Abstract

Abstract

A large number of frames damaged due to the poor lateral stiffness in Wenchuan Earthquake. Additonal flange wall could effectively improve the lateral stiffness. This paper analyzed the bearing capacity of special-shaped column of the practical engineering structures; meanwhile，it was obtained N － M curve and Mx － My curve of biaxial eccentricity compression based on numerical integration method. In addition，the Mx － My envelope diagram of an actual project was also calculated，which could provide a reference for section design and check.
- additional flange wall,
- biaxial eccentricity,
- bearing capacity of normal section,
- numerical integration
