EMUs Pantograph Aerodynamics Experimental Research in Dropping Status under Strong Wind Condition

open access: yes机车电传动, 2016
When EMUs run at a high speed, the pantograph would be affected by airflow and blown up in dropping status, which would result in catenary short-circuit fault. In order to evaluate the pantograph aerodynamics characteristics in dropping status and ensure

Relative dimension of morphisms and dimension for algebraic stacks

open access: yes, 2013
Motivated by applications in moduli theory, we introduce a flexible and powerful language for expressing lower bounds on relative dimension of morphisms of schemes, and more generally of algebraic stacks.

Catenary Action in Rebars Crossing a Casting Joint Loaded in Shear

open access: yes, 2016
Reinforcement crossing a casting joint loaded in shear exhibits catenary action as the shear displacement increases. The load carrying capacity of such a joint is in practice often calculated by use of empirical methods to account for shear friction effects or by a first order plastic analysis if dowel action is included.

Numerical Investigation of Progressive Collapse Resistance in Fully Bonded Prestressed Precast Concrete Spatial Frame Systems with and Without Precast Slabs

open access: yesBuildings
Preventing progressive collapse induced by accidental events poses a critical challenge in the design and construction of resilient structures. While substantial progress has been made in planar structures, the progressive collapse mechanisms of precast ...

Steel Beam-to-Column Friction Joint under a Column Loss Scenario

open access: yesBuildings
FREEDAM joints have been recently seismically prequalified for applications in European seismically prone countries. Despite their excellent seismic response, FREEDAM joints are not purposely conceived for exceptional loading conditions, such as in the ...
