Shadowing of Ultrahigh Energy Neutrinos [PDF]

, 1996
The rise with energy of the neutrino--nucleon cross section implies that at energies above few TeV the Earth is becoming opaque to cosmic neutrinos. The neutrinos interact with the nucleons through the weak charged current, resulting into absorption, and

Local Buckling Influence on the Moment Redistribution Coefficient for Composite Continuous Beams of Bridges

The Baltic Journal of Road and Bridge Engineering, 2010
The present paper is concerned with the elastic design optimisation of continuous composite beams. This optimisation is based on the analysis of the beam in the inelastic range including the concrete creep and shrinkage, the tension stiffening and ...

Stress Redistribution in Statically Indeterminate Corroded Reinforced Concrete Beams

Железобетонные конструкции
The paper deals with the issues of bending moment redistribution in statically indeterminate corroded reinforced concrete beams. It is noted that the ability of a reinforced concrete beam to rotate is crucial for both operational and limit states, as it ...

Premature destruction of two-span RC beams exposed to high temperature caused by a redistribution of shear forces

Journal of Civil Engineering and Management, 2017
When multi-span RC elements are exposed to fire one usually observes a yielding of span cross-sections while a safety reserve of support cross-sections is still significant. Due to this phenomenon a redistribution of bending moments occurs and the values

Structural response of main tunnel linings during construction of connecting aisle by means of mechanized drilling

Yantu gongcheng xuebao, 2020
In order to study the structural safety of the linings of the main tunnel during mechanized cutting, two full-scale tests on segmental tunnel rings are carried out. The specimen each consists of seven rings.

Moment Redistribution in UHPC Continuous Beams Reinforced with High-Strength Steel Bars: Numerical Investigation and Prediction Model

Buildings
Considering moment redistribution in the design of ultra-high-performance concrete (UHPC) statically indeterminate structures can fully exploit the load-bearing potential of members, simplify reinforcement details, and save construction costs. Due to the
