Slender, load-bearing masonry walls with slenderness ratios (h/t) greater than 30 are required to be designed as pinned-pinned elements per North American provisions for masonry, CSA S304-14 (2019) and TMS 402-16 (2016). This provision neglects the contribution of reactive stiffness foundation strength wall its effect on redistribution bending moments along height. Eight full-scale built differ...

Chock-shield support is usually used in undergroud coal mining to protect the roof. However, as depth gets deeper, impact load that came from roof becomes stronger and more frequent. This causes bear a large number of dynamic loads, reducing its reliability. To improve performance chock-shield support, mixed-kinetic model was established using mechanical-hydraulic co-simulation method. The dist...
