We considered double split ring resonators (negative permeability particles) with additional capacitive gaps to compensate for the inertial inductance, as well as complementary double split rings (negative permittivity).
Hybrid metamaterial devices designed for the THz frequency regime were fabricated by combining double split-ring resonators (SRRs) with phase changing VO2 films.
Prequalification of the Double Split Tee (DST) connection has been conducted using hot-rolled shapes, whose availability is still limited in several countries.
A bi-layered chiral structure with double split-ring resonators is proposed to achieve dual-band asymmetric transmission of linear polarization waves propagating forward and backward.
The microplane theory is formulated kinematically using its transformed strain with a double split, namely the volumetric (V) and a deviatoric-tangential (DT) splits.
In this study, we propose guidelines to optimize the transmission and bandwidth of left handed materials (LHM) composed of two-dimensional lattice of metallic wires interleaved with double split ring resonators (SRRs).
Within the beam-to-column joint typologies to be used in seismic resistant steel frames, the double split tee joint (DST) represents an interesting solution due to its easy fabrication and repair after a destructive seismic event.
On the base of past experimental results, the use of dissipative Double Split Tee (DST) connections can be considered a promising solution from the technological standpoint, because they can be easily replaced after the occurrence of a seismic event.
It was concluded that the weld has no effect on the response of the T-stub and, consequently design recommendations for Double Split T connections can be applied when using built-up T-stubs.
The aim of the research is the determination of limit states that control the behavior of built-up T-stubs and the evaluation of the applicability of current design recommendations for double split tee moment connections when the split tees are replaced by built-up T-stubs.
