A universal hub adapter for a portable display frame assembly, the hub adapter being configured to mount to an outer surface of a display hub of the frame assembly. The universal hub adapter is configured to adapt the display hub of the frame assembly between the mounting of a first graphics system including a plurality of stretched fabric panels and a second graphics system including a channeled sub-frame for mounting a larger fabric panel. The universal hub adapter can include a faceplate having a substantially planar outer surface and a concave inner surface configured to mate with the convex outer surface of the display hub and a threaded post having a threaded portion, a securement plate, a button shaft, and a button head, the threaded portion configured to pass through an aperture of the faceplate and couple to the display hub, such that the securement plate abuts up against the faceplate thereby securing the faceplate to the display hub, the button shaft and button head configured to operably couple to one of a stretched fabric panel or a sub-frame assembly.

A clip (2) for fitting between a first component (6) and a second component (4) in a building structure, the clip including a first member (8), a second member (10) and a connecting portion (12) connecting the first member (8) to the second member (10); the first member (8), the second member (10) and the connecting portion (12) forming a space (38) in which a portion of a leg (18) of the second component (4) is adapted to reside; the first member (8) and the second member (10) adapted for engagement with the portion of the leg (18) of the second component (4).

A shape-morphing space frame (SMSF) utilizing the linear bistable compliant crank-slider mechanism (LBCCSM). The frame's initial shape is constructed from a single-layer grid of flexures, rigid links and LBCCSMs. The grid is bent into the space frame's initial cylindrical shape, which can morph because of the inclusion of LBCCSMs in its structure. The design parameters include the frame's initial height, its tessellation pattern (including the unit cell bistable elements' placement), its initial diameter, and the resulting desired shape. The method used in placing the unit cell bistable elements considers the principle stress trajectories. Two different examples of shape-morphing space frames are presented herein, each starting from a cylindrical-shell space frame and morphing, one to a hyperbolic-shell space frame and the other to a spherical-shell space frame, both morphing by applying moments, which shear the cylindrical shell, and forces, which change the cylinder's radius using Poisson's effect.

A pergola comprising a base module having a quadrangular support structure provided with vertical uprights connected to each other by at least one pair of rails and at least one transverse crossbeam connecting the pair of rails. The base module delimits a first roof surface. The pergola includes an extension module having a framework provided with at least one pair of struts. Each strut is at least partially vertically superposed on a corresponding rail, and is provided with at least one support leg that supports the overhanging framework on the side opposite the base module in the longitudinal direction. The extension module delimits a second roof surface at least partially superposed on the first. A guide structure is interposed between the struts and the rails for guiding a reciprocal longitudinal translation between the base module and the extension module, to modify the overall roof surface of the pergola.

A structural frame for a building includes a plurality of columns, beams, and beam-to-column connections. A plurality of braces are positioned in frame bays formed by respective pairs of columns and beams, each brace comprising a multi-piece brace having a plurality of brace portions. A plurality of discontinuous elastic zone connections couple the plurality of beams to the plurality of columns via the plurality of beam-to-column connections and/or couple pieces of the multi-piece brace together. Each of the discontinuous elastic zone connections comprises connection mechanisms and a compression element positioned on each connection mechanism, with each compression element comprising a single component or a plurality of deformable components in a parallel stack, a series stack, or a combination of parallel stacks and series stacks. The compression element is configured to provide elasticity in the structural frame and dampen the effects of transient loads on the structural frame.

A node is disclosed. The node may have a core. The node may also have a projection extending from the core. Further the node may have a structural member attached to the projection. The node may also have a top cover having a top recess. The top recess may be configured to receive the structural member. Additionally, the node may have a bottom cover having a bottom recess. The bottom recess may be configured to receive the structural member. In addition the node may have a fastener to connect the top cover and the bottom cover.

A gusset plate assembly for use in connecting at least two beams to a hollow tubular column in a building. The gusset plate assembly can receive said at least two beams in a biaxial orientation of said beams. The gusset plate assembly comprises gusset plates sized for transferring the weights of said at least two beams and their reaction forces and bending moments from the application of severe load conditions acting on the building to the hollow tubular column. At least one of the gusset plates receives a portion of a second of the gusset plates. A joint penetration groove weld joining the first and second gusset plates together allows the gusset plate assembly to be free of welds on its internal corners. A method of assembling a gusset plate assembly is also disclosed.

A building system comprising a plurality of tubes, a plurality of connection nodes comprising tubular sections for connection to the tubes, wherein the tubes are arranged to connect between the connection nodes to form a frame for a building, wherein at least one continuous cavity is formed through at least a portion of the nodes and tubes when the nodes and tubes are connected, the building system further comprising fluid tight seals between the tubes and connection nodes to enable fluid to flow through the at least one continuous cavity.

An inter-element joint structure including: a first member provided with a hole or a trench; a second member provided with a through-hole; a bushing member fitted to the through-hole formed in the second member and fixed to the second member while the bushing member comes into contact with a surface of the first member; a fastening member including a bolt provided with a shank penetrating at least the bushing member and the hole or the trench of the first member to fasten the bushing member and the first member; and a washer that is interposed between a head of the bolt and the bushing member and has a diameter larger than that of the bushing member. The bushing member has a thickness larger than that of the second member, and the through-hole of the second member has a circumferential edge loosely fitted between the washer and the first member.

A structural assembly including a first structural member defining a first partial bore and including a first protrusion extending from a periphery of the first partial bore on a first side and a second protrusion extending from the periphery of the first partial bore on a second side, a second structural member defining a second partial bore and including a first protrusion extending from a periphery of the second partial bore on a first side and a second protrusion extending from the periphery of the second partial bore on a second side, wherein the second partial bore is aligned with the first partial bore to define a through-bore, a first engagement member engaged with the first protrusions and a second engagement member engaged with the second protrusions, wherein the first and second structural members are clamped between the first and second engagement members.
