A seismic and fire-resistant vertical shaft wall structure is formed by employing a uniquely configured connector above wallboard panels forming the shaft wall at each vertical section of the shaft wall structure. The connectors are formed of strips of sheet metal configured in a manner to seat wallboard panels positioned atop them and receive wallboard panels projecting up from beneath them. The connectors also receive strips of resiliently compressible fire insulation material that fill the gaps between the wallboard panels and the connector at each level of the vertical shaft wall. Interior vertical shafts within buildings, such as elevator shafts, stairwells, and other shafts can be made not only fire resistant but resistant to seismic stresses as well. The system also provides a new method of constructing a superior vertical shaft wall totally from within the structure of the building, without requiring any steps to be performed from within the shaft.
