A parametric numerical study is conducted to quantify the reduction in column buckling strength due to these flexural demands that are not considered in design. An empirical column buckling strength reduction factor that accounts for the reduction in the column buckling strength due to flexural demands is proposed. This reduction factor can be easily implemented with traditional design approaches without considering the flexural demands in the leaner columns explicitly.enginfo:eu-repo/semantics/restrictedAccessConference paper26856952-s2.0-85079096099
