Research Progress on Bending Strength Calculation of Biaxial Compression-Bending Reinforced Concrete Column

Abstract:

Lots of bulidings had collapsed in Wenchuan big earthquake in 2008, one important reason is that the structure design has been launched only in X or Y axis of the building respectively, which means the oblique direction compression-bending characteristic has not been fully considered in the actual structure design process. In addition, the moment bearing strength in oblique direction is smaller than the moment strength about the principle axis of the column, so the research on bending strength calculation of biaxial/oblique compression-bending RC column is important to improve the aseismic safty of the buildings under actual earthquake effects. In this paper research achievements about bearing capacity calculation of column under oblique compression-bending action are summarized and analyzed. At last the advice for actual application has also been given.
