Abstract: This paper presents an experimental study on the fatigue behavior of cracked steel beams strengthened using different patch systems and high-strength materials. These materials included normal modulus carbon fiber–reinforced ...

Abstract: Fly ash (FA), silica fume (SF), and ground blast furnace slag (GBFS) were used as the supplementary cementitious materials (SCMs) in cement paste. The autogenous shrinkage (AS) and the shrinkage cracks of cement paste with ...

Abstract: This paper presents a numerical simulation on the collapse behavior and structural stability of a reinforced concrete superlarge cooling tower subjected to strong winds. Results demonstrated that the cooling tower locally ...

Abstract: The bending fatigue test results on cracked rectangular hollow section (RHS) steel beams repaired with prestressed carbon fiber-reinforced polymer (CFRP) plates are presented. The steel beams were artificially cut on the ...

Abstract: This paper investigates damage and healing of cementitious materials based on fly ash (FA) with a special focus on the effect of repeated loading on the self-healing performance. In total, 90 prism specimens and 33 cylinder ...

Abstract: This study investigates rheological effects of blood on steady flows in a nonplanar distal end-to-side anastomosis. The shear-thinning behavior of blood is depicted by a Carreau–Yasuda model and ...

Abstract: The critical moisture content of concrete with different fibers and the quality loss of different moisture contents are analyzed by simulating the real heating curve of the building material in a fire, and a fire test on ...

Abstract: The Charpy transverse impact experiments on the three-dimensional (3D) multiaxial warp knitted (MWK) composites with four fiber architectures are performed at room and liquid nitrogen temperatures (-196°C). Macrofracture ...
