Hybrid moment frame come together with reinforced concrete columns with structural steel beams (RCS). This Composite system provides several key advantages over current steel or concrete moment resisting frame. Past studies have shown this system to be efficient in both design and building stage while able to keep sufficient strength and necessary ductility in seismic zone.Although past researc...

progressive collapse is a chain reaction of failures propagating throughout a portion of the structure disproportionate to the original local failure occurring when a sudden loss of a critical load‐bearing element initiates a structural element failure, eventually resulting in partial or full collapse of the structure. both general services administration (gsa) and united states department of d...

near-fault ground motions have caused very much damage in the vicinity of seismic sources during recent earthquakes. it is well known that under specific circumstances, intensive ground shakings near fault ruptures may be characterized by short-duration impulsive motions. this pulse-type motion is generally particular to the forward direction, where the fault rupture propagates towards the site...

Steel plate shear walls (SPSWs) are a robust lateral load resistance structure because of their high ductility and efficient energy dissipation when subjected to seismic loads. This research investigates the performance an innovative infill web strip (IWS-SPSW) typical unstiffened steel wall (USPSW). As result, two 1:3 scale specimens IWS-SPSW USPSW with single story bay were built cyclic loadi...

in the present study, the effect of core on shear lag phenomenon in tubular structures is investigated. three different tubular structure models including model without core, model with central core and model with central core but eliminated in last 15 stories have been analyzed. a shear lag index is defined for evaluating these models. from examination of the results, the effective influence o...

Special Plate Shear Wall (SPSW) merupakan struktur rangka yang terdiri dari pelat baja vertikal (infill plate) sebagai dinding pengisi tersambung dengan balok dan kolom, berfungsi untuk menahan beban seismik. Penelitian ini bertujuan mengetahui tingkat kinerja gedung SPSW terhadap variasi penampang kolom menggunakan metode analisis pushover bantuan software ETABS. Struktur klinik 6 lantai, tota...

This paper describes a novel moment matching based fitting method for phase-type (PH) distributions. A special sub-class of phase-type distributions is introduced for the fitting, called generalized hyper-Erlang distributions. The user has to provide only two parameters: the number of moments to match, and the upper bound for the sum of the multiplicities of the eigenvalues of the distribution,...
