Abstract: A structural brace may include a core member, which may include a first end, a second end, and a center portion. The center portion may include a cutout pattern disposed along a length of the center portion. In response to absorption of energy from seismic forces, the core member may provide plastic deformation and may be resistant to buckling. The structural brace may include a housing, which may surround at least the center portion of the core member. The structural brace may include a spacing material between the core member and the housing.
Abstract: Various embodiments disclosed herein relate to moment-resisting frames, kits for assembling such moment-resisting frames, and methods of repairing such moment-resisting frames. In an embodiment, a moment-resisting frame includes a beam connected to a column using a moment-resisting connection. The moment-resisting connection may include at least one exterior doubler plate (“EDP”) that is connected to the column and two or more connectors that are connected to both the beam and the EDP. In some embodiments, the moment-resisting frame may require less welding than conventional beam-to-column connections. Additionally or alternatively, such a moment-resisting frame may eliminate the need for components typically used in conventional beam-to-column connections (e.g., continuity plates).
Abstract: A system may measure displacement in an architectural brace that absorbs deformation inducing energy. The architectural brace may have a core member with first and second ends attachable to architectural features, and an intermediate portion between the first and second ends. The architectural brace may also have a buckling restraining assembly that encases the intermediate portion to resist buckling of the intermediate portion. The system may have a first coupling with a first attachment feature securable to the first end of the core member, and a second coupling with a second attachment feature securable to the second end of the core member. The second coupling may be displaced from the first coupling by a displacement. Further, the system may have a sensor that measures a plurality of changes in the displacement occurring over a period of time. The sensor may provide measurement data indicative of the changes.
