“…To replace traditional reinforcement methods for coupling beams used within shear wall system, Chairunnisa et al modeled a simplified version of a coupling beam using steel truss configurations made from steel angle profiles and found that this kind of steel truss-coupling beam can show fairly well behavior under lateral load 4 . Wang et al proposed an innovative approach with a cold-formed thin-walled steel tube truss shear wall reinforced with oriented strand board on both sides, aiming to meet the seismic capacity requirements for in low- and multi-rise buildings 5 . To investigate the behavior of pitched timber roof structures with long span stabilized by bracing trusses positioned in the plane of the top chord, Sejkot et al performed three parametric studies and found that remarkable support forces may be generated in the compressed structural members of such long-span timber structures 6 .…”

The performance of the heavy-duty escalator truss greatly affects the stability and service life of the whole escalator system, and the manufacturing cost of truss structure accounts for more than 1/5. Thus, how to design the truss structure reasonably is a pivotal issue drawing the attention of numerous engineers and researchers. In this work, the experimental research of heavy-duty escalators under full load conditions were performed in terms of the end restraints, the docking port clearances, and the deflection. Based on the experimental results, the three-dimensional simulation model of truss structure was created, and the influences of various factors such as the internal chamfer of truss member, the lower deviation of truss member, the dead weight of escalator, and the pretension force of each bolt at the docking port were analyzed and quantified. Finally, the finite element model which can almost completely characterize the actual structure was obtained with slight difference. The conclusions drawn in this work provide the basis for the efficient design, correct simulation, low cost production and rapid installation of the heavy-duty escalator truss.

“…A wide range of research has been performed on different applications of lightweight steel frames tested under reversed-cyclic lateral load; however, none of the systems involved steel studs connected to a precast concrete shell. Prior studies include tests of light steel frames with wood panel sheathing as shear walls [16]; stud framed walls having strap bracing and steel covering [17]; steel stud framed walls utilized as braced bays [18]; steel frames with R/C infill walls [19]; non-structural lightweight steel drywall partitions [20]; concrete-filled steel tube truss shear walls [21]; steel-foam concrete composite panels [22]; steel-concrete tube shear walls having horizontal joints [23]; and shear panels formed of steel columns in concrete walls [24]. The research on composite shear panels showed that the ductility of the unmodified composite panel was lower than the reference panel ductility.…”

Two precast concrete thin-shell wall panels were subjected to reverse-cyclic lateral loads to replicate wind fatigue over a 50-year design lifetime prior to loading to failure. The panels consisted of an outer wythe of concrete connected to light-gauge steel framing. Wire mesh was used to reinforce the concrete panel skin. Rivets provided a connection between the steel studs and the concrete panel. Two reinforced concrete (R/C) beams were integrated into the top and bottom parts of the panel, isolated from the concrete face by a thin sheet of extruded polystyrene (XPS) foam insulation. To connect these beams with the concrete face through the rigid foam insulation, a carbon-fiber-reinforced polymer (CFRP) grid was utilized. The aim of the experimental program was to characterize the behavior of the concrete and steel framing panel, with particular attention focused on the connections between the various structural elements of the panel. The first and second thin-shell panels survived the fatigue loading cycles and behaved elastically through failure-level lateral load cycles equivalent to 54 psf (2.6 kPa) and 66 psf (3.2 kPa) of applied uniform load, respectively. The failure mode was the separation of the top R/C beam from the concrete panel on the pull stroke of the loading cycle (when the connection between the beam and the concrete shell was in tension) for both specimens.
