WebEuler–Euler (EE) models describe both the fluid and the particulate phase with transport equations on a globally fixed coordinate system—particles are not tracked in space and … WebPin-Pin Column with Eccentric Axial Load : Generally, columns are designed so that the axial load is inline with the column. These types of columns were analyzed in the previous sections (Basic Columns and Fixed Columns). However, there are situations that the load will be off center and cause a bending in the column in addition to the compression.
