Would this require a complete upgrade of the lateral system in the offending direction? If so, would you not then be obligated to consider improvements for seismic loads? I have seen these wind screens in several places, yet I am sure no one ever upgraded the building due to the wind screen. Jeff SmithAs far as my concern, anyway an engineering report is required to show if such upgrade is necessary or not! So I prefer to upgrade the lateral loads in these cases. Although usually the calculations have enough safety margin to not be affected by small load increasing. That 6 feet height wall in top of a three story building shouldn't be a big deal and as you noticed usually nobody even think about that.
