Abstract: It is 100 years since the well-known Mohr-Coulomb strength theory was established in 1900. A considerable amount of theoretical and experimental research on strength theory of materials under ...

Abstract: At first, we proposed the concept of nominal rigidity of a long-span V-shaped rigid frame composite arch bridge, analyzed the effects of structural parameters on nominal rigidity, and derived a theoretical nominal rigidity ...

Abstract: The authors present a probabilistically complete planning approach for handling the lift path planning problem without prior picking/placing configurations. Firstly, this research introduces the concept of crane location ...

Abstract: Segment design and composition is a vital procedure for controlling the deviations between segment rings and a designed tunnel axis (DTA) to guarantee tunnel quality in the design stage. The novel design technology known ...

Abstract: Excessive ratcheting deformation is a typical failure mode of pressurized pipeline under repeated loads in practice. There are still very few studies regarding the analytical ratcheting limits of pressurized pipes subjected ...

Abstract: Mechanical response of soils under simple shear conditions has long been a subject of significant interest in the field of geomechanics. When subjected to simple shear loading, soils experience rotations of the principal ...

Abstract: This study aims to determine the pounding probability of a continuous rigid bridge with high piers and long span at the actual site soil under the action of an earthquake. Finite-element models of the bridge are built to ...

Abstract: To study the advance distance of guide signs of expressway exits, we divide driving behavior in expressway exits into five processes according to the characteristics of the driving psychology principle and drivers’ response ...

Abstract: Hypergolic bipropellant of monomethylhydrazine (MMH) and nitrogen tetroxide (NTO) is extensively used in spacecraft propulsion applications and rocket engines. But studies on the chemical kinetic mechanism of MMH/NTO are ...
