Abstract: There is disclosed a non-progressive modular wall system for wall heights greater than eight feet that does not require excessive demolition of adjacent wall panels and framing posts above and below the moment connection, typically at the eight foot level. The wall system assembly includes framing at the moment connection comprising connector or junction blocks fastened to the ends of the framing posts. The connector blocks abut each other and are fastened together at the moment connection and allow for selective removal of the framing posts. The disclosed wall system meets the lateral load and deflection requirements for non-progressive wall systems having wall heights greater than eight feet.
