In the extra dimensional scenarios with gauge fields in the bulk, the KaluzaKlein (KK) gauge bosons can induce Nambu-Jona-Lasinio (NJL) type attractive fourfermion interactions, which can break electroweak symmetry dynamically with accompanying composite Higgs fields. We consider a possibility that electroweak symmetry breaking (EWSB) is triggered by both a fundamental Higgs and a composite Hig...

Propagation properties of square, hexagonal and octagonal lattice photonic crystal fibers (PCFs) have been analyzed here for both stressed and unstressed conditions. The analysis has been carried out using finite element method. All types of PCFs are investigated here by varying number of air hole rings with same design and operating parameters. The results show that external stress causes PCFs...

In recent years many research on composite beams with innovative shear transmission with composite dowels have been conducted and innovative composite constructions have been built. One of the common types of shear connection is the method of rolled girders encased in a concrete slab. The combination of such method and pcb (precast composite beam) technology is called pcb-W (precast composite b...

This paper presents the results of an investigation into performance fully encased composite columns under monotonic axial load using finite element simulation. The damage characteristics and specimen were mainly focused on influence compressive strength concrete size reinforcement. material was modeled plasticity (CDP), which incorporates hardening softening behaviors, steel metal plasticity. ...

Composite RCS building frames integrate reinforced concrete columns with structural steel beams to provide an efficient solution for the design and construction of earthquake-resisting structures. In this paper, an optimization framework is developed for performance-based seismic design of planar RCS moment resisting frames. The objective functions are defined as minimizing the construction cos...

Several structural failures occur in the columndue to lack of confinement. The circular column is not popular for regular buildings. use spiral only familiar tothe column. Many design engineers usesquare columns with hoops and cross tiesas As far as authors’ knowledge, therewasonly a study carried out on square columnswith spirals For this reason, authors propose introduce new type innovative c...
