ANCHORING PERFORMANCES ANALYSIS OF TENSION-TORSION GROUTED ANCHOR UNDER FREE AND NON-FREE ROTATING CONDITIONS

چکیده

For the failure mechanism of anchor cable lags behind practice demand for theoretical models, Abaqus technique was used to analyze anchoring performances grouted under conditions free and non-free rotating. The tension-torsion coupling characteristics progressive anchorage segment were studied during pull-out test. torsion response internal horizontal vertical strain changes in concrete also analyzed. Results show that proposed calculation model is verified. With increase pulling-out displacement, load anchored section gradually transferred from inside outside. stress undergoes evolution process rod shape-bell shape-aquarium shape-spear shape. As an intermediate transition layer, agent breaks before at same time plays a buffering effect. Under action coupling, prone tensile-shear composite failure. There are two different ways transmitting force rotating non-rotating conditions, will be reduced state rotation. obtained conclusions can provide reference similar practice. Keywords: Grouted anchor, Tension-torsion Numerical simulation, Failure mechanism, Anchoring

Optimized Mouse BMDC Isolation and Culture under Endotoxin-Free Conditions

Introduction: Dendritic cells are very important in basic studies and vaccine research, but isolation and culture of these cells face challenges due to their small number in tissues. Since there is no standard method, we addressed some of the factors affecting the efficiency of dendritic cell isolation and culture from BALB/c mouse bone marrow.   Materials & Methods: Bone marrow cells isolated...

-torsion free Acts Over Monoids

In this paper firt of all we introduce a generalization of torsion freeness of acts over monoids, called -torsion freeness. Then in section 1 of results we give some general properties and in sections 2, 3 and 4 we give a characterization of monoids for which this property of their right Rees factor, cyclic and acts in general  implies some other properties, respectively.
