The prefabricated walls of the structural system investigated herein seem to meet all the requirements of Eurocode 8 for walls to be designed as "large lightly reinforced walls"; however this assumption should be supported with further experimental and analytical studies.
A quasi-isotropic lay-up was found to result in the highest Specific Energy Absorption (SEA) for Four-Harness (4HS) reinforced laminates; however a hybrid of unidirectional weave and 4HS fabric produced the highest SEA of 114 kJ/kg.
This result suggests that this may be the optimal architecture and density for orthogonally woven Z-fiber reinforced composites, however due to the complex nature of the problem the same architecture with a different tow (and fiber) volume fraction may yield different results.
Multiple criteria have been proposed to describe the mechanism of crack propagation/deflection at the filament scale in brittle matrix continuous fiber reinforced composites; however, most of these criteria fail to account for the presence of an interphase of finite thickness and/or employ unrealistic boundary conditions.
This can be attributed partly to shrinkage induced cracks in the non-symmetrically reinforced sections; however, the uniform distribution of fibers in slabs S2 and S3 can lessen the shrinkage induced cracks.
We all understand the need to invest in prevention and the Care Act reinforces this – however, when councils are under the financial impact that we've been under in Liverpool (£156m reduction over three years) then we naturally focus on how we ensure we meet our statutory duties.
Carbon black and precipitated silica are widely used as rubber reinforcing fillers; however, some new classes of nanosized substances like organophilic modified clay or carbon nanotubes are presently intensive studied as possible future filler systems in combination with carbon black or silica.
RATIONALE: Nicotine and non-nicotine components of cigarette smoke contribute to its reinforcing effects; however, the specific role of each component in maintaining behavior has not yet been elucidated.
Silicon carbide particulates have widely been used as reinforcing element; however, the use of aluminium oxide, boron carbide, graphite, fly ash and bamboo leaf ash also find their application as reinforcing agent during fabrication of aluminium matrix composites.
To satisfy 250 MPa stress limit (Δfps,allow) in the partial PSC members (PPR ≥ 50%) with 550 MPa reinforcing bar, however, the effective prestress (f se ) shall be greater than 0.55 f pu, 0.60 f pu, and 0.50 f pu for the rectangular, T-shaped, and IT-shaped sections, respectively.
