A Z-shaped attachment element for use in building construction is disclosed. The Z-shaped attachment element is made from a single piece of sheet metal that is first cut and then bent to form the Z-shaped cross-sectional profile. The Z-shaped attachment element comprises: an elongated upper flange; an elongated lower flange, wherein the upper and lower flanges are spaced apart and substantially parallel to each other; an elongated middle web section between, and connected to, the upper and lower flanges along respective upper and lower lengthwise bends (wherein the middle web section is diagonal in relation to the position of the upper and lower flanges, thereby defining a generally Z-shaped cross-sectional profile); and a plurality of notches formed along the lower lengthwise bend and into the lower flange and the adjoining middle web section, but not into the upper bend or the upper flange, of the Z-shaped sheet metal attachment element.

A steel wall stud has a rear wall, two parallel side walls, each side wall having a front end wall that projects away from interior cavity formed by the rear and side walls.

A radiation shielding structure or vault includes an outer wall and an inner wall. The outer wall includes at least one outer wall panel formed into a cylinder shape having an outer wall opening. The inner wall includes at least one inner wall panel formed into a cylinder shape having an inner wall opening aligned with the outer wall opening. Tie rods secure the inner wall to the outer wall to support and hold the spacing between the walls. A tunnel structure is inside the inner wall opening and the outer wall opening. A radiation shielding door is coupled to the tunnel structure. A radiation shielding filler material is disposed in between the outer wall and the inner wall.

The disclosed technology provides a seismic yielding connector. The seismic yielding connector includes a U-shaped plate configured to connect a side stud of a panel to another component of a panel and a yielding plate located between the U-shaped plate and the side stud of the panel. A high-strength bolt connects the U-shaped plate, the yielding plate, and the side stud of the panel to a structural column. A bushing is located between the U-shaped plate and the structural column.

The present invention is a method for accessing a model of a building; selecting a set of wall panels; isolating a plurality of the wall panels, wherein the wall panels interface with another wall panels in a horizontal type interface; selecting members of the wall panels involved in the interface, wherein the interface is identified as a connection between the wall panels; detecting the member type and the interface type; calculating a set of actual values associated with the interface type; comparing the set of actual values with a set of required values and determining the delta of the actual values and the required values; and identifying each interface where the delta is outside a predetermined range.
