Deep roadway deformation due to soft rock, rock dip, and horizontal tectonic stress is uneven asymmetrical primarily in large loose zones. Traditional anchor support influenced by the yield strength shear of anchors has a limited prestress capacity or resistance. When roof laminated when passes through layered interfaces, interlayer sliding commonly occurs, which can easily lead cables being sh...

The limited transferring moment capability of Glulam (glued laminated wood) joints results in insufficient joint stiffness. Therefore, most the connections are hinged joints. Based on previous studies, one novel end-connection device was proposed to form prestressed continuous beams. beams were composed low-relaxation steel bars, deviator block, anchorage device, and apparatus. These bars tensi...

We develop a general approach to study the equilibrium and form-finding of any tensegrity systems with rigid bodies. The equations are derived in an explicit form terms nodal coordinate orientation parameter as minimal coordinate. vector consists nodes (either free or pinned) pure bar-string network on bodies (those connected network). Based Lagrangian method, nonlinear statics system is first ...
