I suggest you read up on the subject. the leaning column is added to account for the P_Delta effects on the lateral system from the gravity columns in the rest of the building. The way people model it is as you described and is as described by many others in the litarture. Now if this column is added and it OpenSees is an advanced performance simulation software framework for structural and geotechnical facilities. The software is designed to integrate the implementations of models for structural behavior, soil and foundation behavior, and damage measures. Unlike traditional codes, OpenSees is designed to be implemented in a modular, object PDelta Transformation. This command is used to construct the P-Delta Coordinate Transformation (PDeltaCrdTransf) object, which performs a linear geometric transformation of beam stiffness and resisting force from the basic system to the global coordinate system, considering second-order P-Delta effects. NOTE: P LARGE Delta effects do not The goal of the OpenSees development is to improve the modeling and computational simulation in earthquake engineering through open-source development. OpenSees is under continual development, so users and developers should expect changes and updates on a regular basis. In this sense, all users are developers so it is important to register . Also i can see that my Opensees Model has no way of getting P-delta effects activated because Neither two node link element nor the shell elements used to model the boxes have coordinate transformation feature.
