In this study, impacts of residual stress and shear deformation are investigated on 2D steel frames using a new fiber plastic hinge method. Geometry material nonlinearities, stress, deformation, imperfections considered simultaneously in the nonlinear analysis. The proposed method is efficient computational efforts since one-element modeling used for analysis by employing stability functions ca...

This study aims to produce Ultra-High-Performance Concrete utilizing locally available material. The experimental includes silica fume with rice husk ash in combination steel fibers. Various trials were made using different volumes of local materials and fibers UHPC. Different properties evaluated, such as compressive strength, tensile Scanning Electron Microscopy (SEM). Results show that UHPC ...

Abstract This paper primarily examines the flowability, physical appearance, mass loss, residual compressive strength (RCS), and flexural (RFS) properties of steel (ST) basalt (BA) fiber‐added sustainable ultra‐high performance geopolymer cement (UHPGPC) mortars exposed to high‐temperature effects. According results obtained, ST BA fibers adversely influence workability UHPGPC thus significantl...

This study proposed a prediction formula for the torsional strength enabling to reflect the tensile strength of ultra high performance concrete (UHPC) beams based upon the thin-walled tube theory. The remarkable ductile behavior of UHPC can also be attributed to the steel fiber reinforcement. This feature must be considered to provide rational explanation of the torsional behavior of UHPC struc...

Cement-based materials are widely used in the civil infrastructure. Polymers as admixtures can improve the properties, particularly in relation to water absorption reduction, toughness enhancement, vibration damping and increase of the bond strength of cement to reinforcements. Polymeric admixtures include particles, short fibers and organic liquids. Latex in the form of an aqueous particle dis...

The microstructure evolution of Fe-17 wt. % Cr-12 wt. % Ni-2 wt. % Mo stainless steel fiber felts during the fast sintering process was investigated by the synchrotron radiation X-ray computed tomography technique. The equation of dynamics of stable inter-fiber neck growth was established for the first time based on the geometry model of sintering joints of two fibers and Kucsynski’s two-sphere...
