Abstract
A shear parameter for a beam element is newly defined. Shear parameters of built-up members are computed under the definition and discussed for the estimation of shear deformation effect. And effective length factors of framed built-up column considered beam-column connection deformation are also discussed in comparison with the current design formula. Some results are : 1) The shear parameters for built-up members formulated herein are available for the estimation of shear deformation effect of members in frame analyses. 2) The differences between effective length factors of framed built-up columns considered beam-column connections and ones neglected beam-column connections are not remarkable in frames with adequately stiffened beam-column connections. 3) The extended alignment charts, which were suggested before, considered shear deformation of members are recommended for the practical design of built-up columns.
