Abstract: Sliding resistance of the main cable is of the biggest concern when designing multispan suspension bridges. This paper presents a study on the layout form and sliding-resistance stability of the main cable in a double-cable ...

Abstract: This paper presents an original Hexacopter with three nonplanar rotor pairs where the variable thrust is provided by fixed-pitch rotors with variable speed. The corresponding face-to-face rotor pair (F–F) and back-to-back ...

Abstract: The climatic responses to the direct radiative effect of dust aerosol at the Last Glacial Maximum (LGM) are examined using a general circulation model with online simulation of dust. The predicted global dust emission at ...

Abstract: In this study, the changes in the phase and microstructure of alkali-activated slag (AAS) in ultralow-temperature environments (−170°C) was experimentally studied by means of X-ray diffraction (XRD), Fourier transform ...

Abstract: The durability of alkali-activated slag grouting materials (AASGMs) has attracted significant research attention. This paper investigated the mechanical properties and microstructure of AASGMs mortars and pastes immersed ...
