The simplified analysis is based on assumptions: -neglecting side-way due to asymmetry in loading and stiffness, -uniform I values for each member, -elastic behavior of all members and joints, -member affected only by the member connected directly to it.The simplified analysis is based on assumptions: -neglecting side-way due to asymmetry in loading and stiffness, -uniform I values for each member, -elastic behavior of all members and joints, -member affected only by the member connected directly to it
