چکیده
This paper examined the opportunities of composite double-layer grid superstructures in short-to-medium span bridge decks. It was empirically shown here that a deck system action with thin layer two−way reinforced concrete slab introduced several structural advantages over conventional plate-girder superstructure system. These included improved seismic performance, increased rigidity, reduced vibration, failure capacity, and so on. Optimally proportioned space were found to be less prone progressive collapse, increasing reliability resilience, while reducing risk sudden failure. Through set dynamic time-series experiments, considerable enhancement load transfer efficiency transverse direction under truck loading gained. Furthermore, multi-objective generative optimization proposed spatial (with integral variable depth) using evolutionary methods examined. Finally, comprehensive discussions given on: (i) mechanical properties, such as fatigue behavior, corrosion, durability, behavior cold environments; (ii) health monitoring aspects, ease inspection, maintenance, access for installation remote devices; (iii) sustainability considerations, reduction embodied Carbon energy due material waste, along demolition, deconstruction reuse after lifecycle design; (iv) lean management support industrialized construction mass customization. concluded shows promise building essential sustainable infrastructures future.

Investigation of Double-layer Grid Space Structurer Resistance to Progressive Collapse
Considering the vulnerability of double-layer grid space structures to progressive collapse phenomenon, it is necessary to pay special attention to this phenomenon in the design process. Alternate path method is one of the most appropriate and accepted methods for progressive collapse resistant design of structures. Alternate Path Method permits local failure to occur but provides alternate pat...

متن کاملPhonon Mediated Transresistivity in a Double Layer Composite Fermion System
We consider the fractional drag in a double layer system of two-dimensional electrons in the half-filled lowest Landau level. At sufficiently large interlayer separations the drag is dominated by exchange of acoustic phonons and exhibits novel temperature and inter-layer distance dependences. At low temperatures the phonon mediated drag is strongly enhanced with respect to the case of zero magn...
متن کاملGauge Fields and Pairing in Double-Layer Composite Fermion Metals.
A symmetrically doped double layer electron system with total filling fraction ν = 1/m decouples into two even denominator (ν = 1/2m) composite fermion ‘metals’ when the layer spacing is large. Out-of-phase fluctuations of the statistical gauge fields in this system mediate a singular attractive pairing interaction between composite fermions in different layers. A strong-coupling analysis shows...
