the top cover plate has a first hole, and
the bottom cover has a second hole configured to threadingly receive the fastener passing through the first hole.
4. The node of claim 1 , further including a gap between the top cover and the bottom cover.
5. The node of claim 1 , wherein the top recess is coaxial with the projection extending from the core.
6. A node, comprising: a top cover including a top recess configured to receive a structural member; and a bottom cover including a bottom recess configured to receive the structural member, wherein the top cover includes: a top cover plate having a top cover edge, the top cover plate being flat and planar with an upper surface having a flat portion that is flat from a central portion to the top cover edge, and a side section attached to the top cover plate at the top cover edge, wherein the side section includes: a recess portion including the top recess extending from a recess leading edge to a recess trailing edge, and a transition portion extending from the recess portion to the top cover edge, wherein the transition portion includes a transition edge disposed adjacent the top cover edge, and the transition edge is welded to the top cover edge, a weld interface between the top cover edge and the transition edge being linear and parallel to the flat portion of the upper surface of the top cover plate, wherein the side section is a first side section, the recess leading edge is a first recess leading edge, the recess trailing edge is a first recess trailing edge, and the top cover further includes: a second side section having a second recess portion extending from a second recess leading edge to a second recess trailing edge, and a web section having a web leading edge, a web trailing edge, and a web outer edge, wherein the web leading edge is attached to the first recess trailing edge, and the web trailing edge is attached to the second recess leading edge, and wherein the first recess portion of the first side section and the second recess portion of the second side section extend outward from the first and second transition portions, respectively, parallel to the flat portion of the upper surface of the top cover plate that is flat from the central portion to the top cover edge.
7. The node of claim 6 , wherein the web section has a generally triangular shape.
8. The node of claim 6 , wherein
the top cover plate has a first hole, and
the bottom cover has a second hole configured to threadingly receive a fastener passing through the first hole.
9. The node of claim 6 , further including a gap between the top cover and the bottom cover.
10. The node of claim 6 , further comprising a core, the core being configured to be enclosed inside of the top cover and the bottom cover when the top cover and the bottom cover are connected together.
11. The node of claim 10 , wherein the top recess is coaxial with a projection extending from the core.
12. A top cover for a node, comprising: a top recess configured to receive a structural member; a top cover plate having a top cover edge, the top cover plate being flat and planar with an upper surface having a flat portion that is flat from a central portion to the top cover edge; and a side section attached to the top cover plate at the top cover edge, wherein the side section includes: a recess portion including the top recess extending from a recess leading edge to a recess trailing edge, and a transition portion extending from the recess portion to the top cover edge, wherein the transition portion includes a transition edge disposed adjacent the top cover edge, and the transition edge is welded to the top cover edge, a weld interface between the top cover edge and the transition edge being linear and parallel to the flat portion of the upper surface of the top cover plate, wherein the side section is a first side section, the recess leading edge is a first recess leading edge, the recess trailing edge is a first recess trailing edge, and the top cover further includes: a second side section having a second recess portion extending from a second recess leading edge to a second recess trailing edge, and a web section having a web leading edge, a web trailing edge, and a web outer edge, wherein the web leading edge is attached to the first recess trailing edge, and the web trailing edge is attached to the second recess leading edge, and wherein the first recess portion of the first side section and the second recess portion of the second side section extend outward from the first and second transition portions, respectively, parallel to the flat portion of the upper surface of the top cover plate that is flat from the central portion to the top cover edge.
