Using of CFRP carbon sheets because of their high strength, lightness and ease of use have been very expanded in retrofitting concrete members. Including shear walls systems FRP can be used in order to rebuild or maintain the strength of an aged structural member. Repairing, or retrofitting of the intact structural member is conducted to enhance the structural resistance that was deteriorated d...

• Fire performance of different 3DPC wall configurations (solid, cavity, and composite) under standard fire conditions was investigated. A suitable heat transfer finite element models were developed the validation showed a good agreement with test data. Extensive parametric analyses undertaken for ten five densities. Significant improvement identified increase material density thickness walls. ...

This paper analyses the current distribution in no-insulation (NI) coils a layer-wound configuration. The investigation aims at comparing electrical characteristic of two wound from same BSCCO tape, with or without insulation between turns. Both are characterized by very similar geometry, number turns and layers. coils, cooled liquid nitrogen bath, charged until tape critical is exceeded. To in...

Electronic Laser Shearography is a relatively new Nondestructive Evaluation (NDE) technique that is used with excitation methods to measure differential displacements and subsequent strains at the surface of a material. Laser shearography was evaluated as an NDE technique for the inspection of adhesive bonds on fixed foam insulation for Atlas-Centaur cryogenic fuel tanks. A test program was con...

In recent years, fabricated composite wall panels have been widely used in building materials markets at home and abroad, their main advantages are convenient construction, low energy consumption, heat sound insulation. However, also some common problems practical applications, such as large dead weight, weak seismic performance, prone to cracks, failing meet the higher energy-saving requiremen...

We present a methodology for creating a simulated foam microstructure for use in forward simulations of wave equations to quantitatively analyze the expected scattering phenomenon primarily responsible for the attenuation of interrogating signals in Sprayed-On Foam Insulation (SOFI). Our approach builds off of the popular use of Voronoi Tessalations for crystal growth modeling by using the Lagu...

Abstract Buildings are more vulnerable to faults in design and construction, when exposed the extreme Greenlandic climate, however, most new materials designs have not been tested for Arctic conditions. Thus even minor errors can result failures like mould growth, discomfort, unnecessary heat loss. Rekognizing source of error be difficult, yet valuable. But how it identified whether lies or qua...

Domain wall solution for Nc = Nf supersymmetric QCD is constructed. Astrophysical implications of the domain wall configuration is also discussed. [email protected] 1

The seismic performance of recycled aggregate concrete (RAC) composite shear walls with different expandable polystyrene (EPS) configurations was investigated. Six concrete shear walls were designed and tested under cyclic loading to evaluate the effect of fine RAC in designing earthquake-resistant structures. Three of the six specimens were used to construct mid-rise walls with a shear-span ra...
