Abstract: The demolition issue of long-span spatial lattice structures has become increasingly prominent with the rapid urban development and building upgrades. Building deconstruction offers superior economic and environmental ...

Abstract: Steel angles acting in tension can be used singly or in pairs. In either case, it is not usually possible to connect both legs. This means that the effectiveness of the member must reflect the shear lag that is present in ...

Abstract: This paper proposes a method of the preliminary geometric design for gear tooth profiles based on given sliding coefficients. A design procedure is developed and a simplified derivation of the ...

Abstract: Postgrouting at the pile tip can improve the behavior of pile shaft resistance through the grout returned along the pile shaft. The soil radial unloading effect that existed in the bored pile shaft soil and the cement ...

Abstract: An elastic–plastic–sliding trilinear load transfer model is established for grouted piles. This model summarizes the resistance–displacement relationships at both the side and tip of the pile, describing the transition ...

Abstract: This study introduces a unified cylindrical and spherical cavity reverse expansion model to simulate the formation of compaction grouting bodies and grout diffusion along pile shafts. Stress field expression employs the ...

Abstract: The influences of free-stream turbulence and Reynolds number on the aerodynamic characteristics of a semicylindrical roof have been investigated experimentally under uniform flow conditions. Grids were used to generate ...

Abstract: A novel friction drive—a metal belt drive with magnets (MBDM)—is proposed in this paper, and its structure and principle are introduced. Based on theories of friction drive and electromagnetism, ...

Abstract: Airport cement pavement is prone to severe freeze–thaw damage due to the use of deicing chemicals. There is no unified evaluation parameter for analyzing the relationship between the concrete meso-structure and its salt-frost ...
