A deck framing system includes a perimeter support member that has a joist support wall and a web wall extending perpendicularly from the joist support wall. Each of a plurality of joist support brackets comprising an attachment portion configured to be attached to the web wall of the perimeter support member and a joist support portion. The joist support portion includes a pair of opposed lateral walls with each lateral wall configured to be attached to a corresponding lateral wall of a joist supported by the joist support wall.

A bollard panel having adjacent bollards and a gap between the adjacent bollards, a brace having a panel connector, a first longitudinal section, and a second longitudinal section, and the brace supporting the bollard panel in a vertical position relative to a ground with the brace disposed in the gap with the first longitudinal section located on a first side of the bollard panel, the second longitudinal section located on a second side of the bollard panel, and the panel connector attached to the bollard panel.

A structural member section is provided that may be comprised of horizontal top and bottom flange elements interconnected by one or more vertical web member. The top flange of the member is serrated such that a series of serrations protrude horizontally in at least one direction from a top of the one or more vertical web member or are cut-out from the flange of a rolled shape. In one embodiment, the serrated top flange and at least a portion of the web member are intended to be encased by a horizontal concrete slab or slab-on-deck assembly. The slab material is capable of encasing all exposed surfaces of and curing around each serration to transfer horizontal shear forces between the serrated top flange and the slab material such that the member and slab behave compositely without needing additional reinforcing located within the voids between serrations.

A structural member comprising a first round flange, a second round flange substantially parallel to the first round flange, an elongate web disposed between the first and second round flange, the web having an upper edge, and a lower edge, wherein the first round flange, the second round flange and the elongate web are secured together to form a structurally integral unit. The structural member may further comprise a third round flange and a fourth round flange substantially parallel to the third round flange, wherein the round flanges and the elongate web are secured together to form a structurally integral unit in which the first face of the web is in contact with the first round flange and the third round flange, and the second face of the web is in contact with the second round flange and the fourth round flange.

In an H-section steel, which has a predetermined chemical composition, a thickness of the flange is from 25 to 140 mm; an average crystal grain diameter is 38 μm or less and the area fraction of a martensite-austenite constituent is 1.2% or less, in a plane orthogonal to the width direction of the flange, centering on a measurement position 7 that is a position separated, in the width direction of the flange, from the end face in the width direction of the flange by (⅙)F, and separated, in the thickness direction of the flange, from the outer face in the thickness direction of the flange by (¼)t.sub.2, when the width direction length of the flange is F and the thickness of the flange is t.sub.2; a yield strength or 0.2% proof stress is 385 MPa or more and a tensile strength is 490 MPa or more, in the rolling direction of the flange, when measured with respect to the entire thickness in the thickness direction of the flange at a position separated in the width direction of the flange from the end face in the width direction of the flange by (⅙)F; and the absorbed energy in a Charpy test at the measurement position 7 at −20° C. is 200 J or more.

To provide a building frame for constructing a building, the frame being stronger than reinforced concrete, and being able to be relatively easily assembled at a construction site, without skills, and within a short time. Provided are a building frame and the like, the building frame being characterized by comprising: U-shaped parts that are arranged left and right so as to sandwich a center space in a cross-sectional view; and a connection part that connects top portions, on the center side, of the left and right U-shaped parts so as to form a reverse U-shaped part, wherein the longitudinal edges, on the far side from the center, of the U-shaped parts arranged left and right in the cross-sectional view are shorter than the longitudinal edges, on the center side, connected by the connection part.
