TL;DR: In this paper, three non-seismically detailed interior reinforced concrete beam-column joints, namely, one eccentric and two concentric joints, strengthened with proposed fiber-reinforced polymer (FRP) wrapping configurations using glass fiber reinforced polymer and carbon fiber- reinforced polymer strips and sheets, were tested under constant axial compression load and reversed cyclic loading which simulated low to moderate earthquake forces.
Abstract: Three nonseismically detailed interior reinforced concrete beam-column joints, namely, one eccentric and two concentric joints, strengthened with proposed fiber-reinforced polymer (FRP) wrapping configurations using glass fiber-reinforced polymer and carbon fiber-reinforced polymer strips and sheets, were tested under constant axial compression load and reversed cyclic loading which simulated low to moderate earthquake forces. Seismic performance of the strengthened beam-column joints in terms of their hysteresis response, stiffness, and energy dissipation capacity is evaluated and compared to those of the original and unstrengthened beam-column joints. Results indicate that applying strips at 45o on a flushed eccentric joint core and as cross bracing on the beam and confinement round the column is very effective. All specimens failed with gradual strength deterioration, bond degradation, and debonding of FRP sheets was observed near the joint core. The proposed strengthening schemes were found to be effi...

TL;DR: In this article, a bracing system consisting of cables and a central energy dissipating device, Couples resisting (CORE) damper, is presented for relatively small rehabilitation projects for steel structures.
Abstract: The goal of this study is to design and evaluate simple and rapid seismic retrofit devices for relatively small rehabilitation projects for steel structures. These designs are consistent with the tenets of sustainable design and will result in a more resilient building stock as well as minimizing environmental and economical effects and social consequences during the rehabilitation project. To achieve these goals, a unique approach to designing supplemental systems by using tension-only elements is proposed, one that eliminates undesirable global and local buckling. The first generation of these devices, a bracing system consisting of cables and a central energy dissipating device [couples resisting (CORE) damper], is presented in this paper. Both analytical studies with advanced and simplified models and proof-of-concept testing demonstrated stable, highly efficient performance of the system under seismic loads. Preliminary applications of the CORE damper system to the retrofitting of a braced steel fram...

TL;DR: A deployable truss with modified primary orthogonal joints is described in this article, which allows the truss to deploy one bay at a time in a stable manner while having lateral bending stiffness, and thus can extend and retract in a sequential manner.
Abstract: A deployable truss with modified primary orthogonal joints. The construction of these joints causes the center-hinged primary chords on opposite sides of a truss bay to fold inward in a plane orthogonal to the folding planes of the side diagonals while the two secondary chords fold in planes orthogonal to the plane of the in-folding primary chords. This provides for stiffness and stability during deploy and retract. The unique joint configuration permits the truss to deploy one bay at a time in a stable manner while having lateral bending stiffness, and the truss thus can extend and retract in a sequential manner. It can deploy integral flat panels nested between the secondary folding chords, or use cross bracing in lieu of panels. The truss can be triangular, square or rectangular in cross-section. A powered support frame may be used in conjunction with the truss.

TL;DR: A portable table with integral seating is described in this article, where the table top, bench seats and braced leg assemblies are removably and interlockingly attached to two crossbeams.
Abstract: A portable table with integral seating is disclosed. All of the components of the inventive apparatus fit within a carrying case which also serves as the table top. Unique standoffs and corner braces are pivotally attached to the table top which folds for storage. The table top, bench seats and braced leg assemblies are removably and interlockingly attached to two crossbeams. The bench seats are uniquely attached by pairs of pegs and holes which are at right angles which trap the seats and provide stiffness to the assembly. Folding legs are pivotally attached to braces which when unfolded provide strong cross bracing.

TL;DR: In this article, the feasibility of building a transmission tower from a composite material, E-glass and Vinylester, was studied and the lamina of the leg member and the cross bracing were tested and compared with two analytical failure criteria, Yeh-Stratton Criterion and Quadratic Criterion.
Abstract: This paper will study the feasibility of building a transmission tower from a composite material, E-glass and Vinylester. The tower was fabricated using a fabrication process called pultrusion. Also instead of using the conventional fastener method to join the cross members to the leg members, the design team utilized a slip joint that was developed by Goldsworthy EngineeringThe lamina of the leg member and the cross bracing were tested and compared with two analytical failure criteria, Yeh-Stratton Criterion and Quadratic (strain space) Criterion. In addition to ply failure analysis a full scale tower tests were performed at Electrical and Power Research Institute.
