This study evaluated the effect of macro steel fiber (SF), micro glass fiber (GF) and micro polypropylene fiber (PF) in lightweight aggregate concrete, (LWAC) beams reinforced with glass fiber reinforced polymer (GFRP) bars. Firstly, concrete mixtures with different volume fractions of GF, PF and SF were tested up to compressive strength, then determine the optimum fiber content GF, PF and SF a...

External installation of steel braces is an effective approach to increase the lateral load resistance moment-resisting frames. However, effects existence on robustness frames resist progressive collapse still not clear because little study has been carried out. To fill this gap, in paper, six multistory subframes (three bare and three braced frames) were fabricated tested. Test results indicat...

In order to investigate the impact of fatigue damage on ultimate load capacity criticality cells in steel–concrete composite segments and address complex design challenges associated with bridge practical engineering, this study designs two scaled cell specimens a scale ratio 1:2 performs tests after cyclic loading. By analyzing stress distribution each component force transmission combining re...

In reinforced concrete design, there are situations where transfer of shear across a specific plane needs to be considered. Examples of such situation include corbels, bearing shoes, ledger beam bearing, and a host of connection between precast concrete elements. In this study, the shear transfer behavior of reinforced concrete is investigated experimentally by conducting test on 6 precracked p...

OBJECTIVES This study compared the biomechanical fatigue strength of calcium phosphate augmented repairs versus autogenous bone graft (ABG) repairs in lateral tibia plateau fractures. METHODS Eight matched pairs of tibias (six male, two female; age, 75 ± 14 years) were harvested from fresh-frozen cadavers. Reproducible split-depression fractures were simulated and repaired by an orthopaedic t...
