recently, two of the authors have introduced the collapse capacity spectrummethodology, which allows the assessment of the collapse capacity of highly inelastic p-deltasensitive regular frame structures without performing non-linear time-history analyses. the mainingredient of this method is the collapse capacity spectrum, which represents the seismic collapsecapacity of an inelastic non-deteri...

In this study, the co-operation of steel and concrete in composite columns is considered. Using numerical modeling to study the behavior of these sections, a new type of sections, namely Concrete Filled Double-Skin steel Tubular (CFDST) columns, is introduced. The parameters and techniques that influence the numerical simulation that bring this modeling closer to...

Lapidoth and Moser have recently proposed a general technique for obtaining upper bounds on channel capacity via a dual expression in which the maximization over probability distributions on the channel input alphabet is replaced with a minimization over probability distributions on the channel output alphabet. They have also introduced the notion of “capacity achieving input distributions that...

Usually the capacity of multiple-input multiple-output (MIMO) wireless communication channels is evaluated under the assumption of fixed signal to noise (SNR) scenario. In this paper the impact of temporal SNR variation on capacity of MIMO wireless channels in urban microcells is considered. Results based on data measured in line of sight (LOS) and non line of sight (NLOS) propagation scenarios...

In this study, two short precast concrete columns and two cast-in-situ concrete columns were tested under cyclic loads. It was shown that the sleeve grouted connection was equivalent to the cast-in-situ connections for short columns when the axial compression ratio was 0.6. In order to determine the influence of the axial compression ratio and the shear-span ratio on the shear capacity of the h...
