A modular expansion joint (e.g., for a bridge) can include an upper expansion support exhibiting a hinge design arranged for pivoting about a vertically extending axis. The upper expansion support underneath may be accompanied by a moisture seal and/or a lower expansion support. The modular expansion joint may include two beams that may be spaced apart by a gap into which the upper expansion support etc. can be received. Each of the two beams can include a top flange defining a top surface and a web extending from the flange. The upper expansion support can be positioned between the top flanges, while the lower expansion support can be positioned between the webs, for example. The upper expansion support may provide a continuation of a travel surface across the beam tops and may accordingly reduce pressure spikes and/or noise from tires moving across the travel surface.

A strut-and-node truss design that is applicable to all space frame structure designs can be made with using robotic (semi-autonomous and/or fully autonomous) or telerobotic assembly/joining. Nodes can include a 2-dimensional weld path in an effort to reduce the complexity of having to weld in 3-dimensions. Furthermore, each strut to node connection can be concentrated in a small area where each weld can be performed robotically from a fixed position that only requires the robotic weld head to swivel in a small operating window to reach each joint.

A bridge structure comprises a first supporting structure, at least one first hollow tube and a first monitor. The first supporting structure comprises bases, first pillars, a first platform. The first pillars are coupled to the bases, wherein each of the first pillars comprises first pillar chords and first pillar girders formed as first pillar trusses with the first pillar chords. The first platform is coupled to the first pillars, wherein the first platform comprises a first supporting plane, first platform chords and first platform girders formed as first platform trusses with the first platform chords. The at least one first hollow tube is located between the first pillar trusses or the first platform trusses. The first monitor is located in the at least one first hollow tube, wherein the first monitor is capable of monitoring a bridge stability.

The assembly comprises a structural cable comprising tendons (12) and a saddle deflecting the structural cable between the two ends thereof. The saddle comprises a body (18), conduits (24) formed in the body and each receiving one of the tendons of the cable, and two anchoring devices (20) which anchor the tendons by defining a first portion of the structural cable received in the saddle, where the tendons are subject to a prestressed tension that is constant over time and at least one second portion of the structural cable where the tendons are subject to tensions that are variable over time. An anchoring device (20) comprises an anchoring plate (28) comprising anchoring openings (36) each receiving one of the tendons, and wedges (30) each received in a respective anchoring opening of the anchoring plate in order to lock one of the tendons of the structural cable. The anchoring plate (28) has a rear surface bearing against the body (18).

A hollow profile (1, 15), in particular crane girder for a crane (14), wherein the hollow profile (1, 15) has a cavity (2) and an outer wall (3) bounding the cavity (2), and at least one fastening element (4) protruding from the outer wall (3) for the, preferably re-releasable, fastening of at least one add-on part (5) to the hollow profile (1, 15), wherein the outer wall (3) has at least one passage opening (6), which opens into the cavity (2), for the fastening element (4), and an intermediate space between that portion (36) of the outer wall (3) which bounds the passage opening (6) and the fastening element (4) which is guided through the passage opening (6) is sealed with a sealing compound (7).

The present application discloses a bridge structure comprising first supporting structure, at least one first hollow tube and a first monitor. The first supporting structure comprises bases, first pillars, a first platform. The first pillars are coupled to the bases, wherein each of the first pillars comprises first pillar chords and first pillar girders formed as first pillar trusses with the first pillar chords. The first platform coupled to the first pillars, wherein the first platform comprises a first supporting plane, first platform chords and first platform girders formed as first platform trusses with the first platform chords. The at least one first hollow tube is located between the first pillar trusses or the first platform trusses. The first monitor is located in the at least one first hollow tube, wherein the first monitor is capable of monitoring a bridge stability

The description relates to bridge truss systems. On example can include a steel truss that includes a top cord spaced away from a bottom cord and multiple web members secured between the top cord and the bottom cord. A deck can be positioned on the top cord of the steel truss.

A joint for a support structure comprises a first beam having a first channel defined therein and a second beam inserted through the first channel of the first beam. The exterior surfaces of the second beam are connected to edges of the first channel.

A high-damping rubber isolation bearing, an intelligent bearing and a bearing monitoring system are disclosed. The high-damping rubber isolation bearing comprises a top bearing plate, a bottom bearing plate, a high-damping rubber bearing body and a base plate, wherein at least one pressure sensing unit is arranged between the top bearing plate and the base plate, or between the bottom bearing plate and the base plate. The intelligent bearing includes a data acquisition unit, a data output unit and the high-damping rubber isolation bearing. The data acquisition unit transmits the bearing pressure measured by the at least one pressure sensing unit to the data output unit. The bearing monitoring system includes a data acquisition unit, a data output unit, a monitoring center and the high-damping rubber isolation bearing.
