The column-tree constructional schemes allows for a reliable and convenient erection of moment resisting steel frames. Strengthening of column-tree connection with a haunch part can significantly improve seismic behavior of whole system. In the current study behavior of column-tree connections with haunched beams and end plate splices have been investigated. Special attention was paid for evalu...

Shallow bias tunnels are sensitive at the entrance section, where existence of soil–rock interface (SRI) results in more complex deformation surrounding rock and supporting structure. This study investigates mechanical properties structure a shallow-buried tunnel crossing by combination model tests numerical simulations. A biased with significant cracking its section is selected southwest China...

The foundation of a seismic safety assessment cross-fault hydraulic tunnels is an acceptable and accurate response. A dynamic contact force algorithm that may take into consideration the interaction between fault–surrounding rock–lining structure was devised in light characteristics various media under activity. quantitative instability criterion using relative displacement ratio as based on cu...

The beef classification technique Video-Image-Analysis (VIA) allows a clear specification of the carcass quality. An objective of our study was to identify possible applications of carcass quality describing parameters for the quality and information management of beef production chains. In addition to the EUROP-classes important key figures are value determining commercial primal cuts of haunc...
