Abstract: Inclined independent column is a key position to Guangzhou New Library. The seismic performance objective of this column is in elastic state under rare earthquake. Construction and finite element analysis of independent column joints, embeded scheme and calculation method of effective length coefficient of independent column were presented. The method of calculating the effective length coefficient based on the integrated model was adopted, through which the boundary constraint conditions and the bearing capacity of components can be reflected more accurately.

Keywords: inclined independent column; finite element analysis; stability analysis; effective length
