the direction perpendicular to the line load to record tensile strain, and a force sensor is used to record the force applied; then the stress–strain curve can be obtained; finally the Et can be calculated according to those related formulas which are derived on the basis of elasticity ...
load outside the contact zone.By numerically solving the left-side and right-side contact lengths of the beam,a criterion is established to determine whether the concentrated load is inside or outside the contact zone.A more general approach on the tensionless contact of a beam is thus ...
Aeroelastic instabilities are dangerous phenomena, where aerodynamic load interacting with the inertia and elastic structural loads can induce catastrophic... LAITH K. ABBAS,Q. CHEN,P. MARZOCCA,... - 《International Journal of Bifurcation & Chaos》 被引量: 4发表: 2011年 High heat flux roll and...
Engineers have proposed the idea that there may be some arching-action present in bridge deck cantilever overhangs subjected to a concentrated load. An experimental research program was undertaken at the University of Manitoba to investigate this hypothesis. This paper includes the details of the ...
CALCULATION ANALYSIS OF SHEARING SLIP FOR STEEL-CONCRETE COMPOSITE BEAM UNDER CONCENTRATED LOAD The strain difference of steel and concrete under vertical concentrated load was analyzed on the basis of elastic theory, and was compared with ideal solut... 刘寒冰,刘文会,张云龙 - 《Applied Mathematics\...
An inverse problem of elastica of a variable-are-length beam subjected to a concentrated load is investigated.The beam is fixed at one end,and can slide freely over a hingesupport at the other end.The inverse problem is to determinethe value of the load when the deflection of the action ...
A finite element formulation has been used to investigate the dynamic stability boundaries of a uniform cantilever column subjected to an intermediate general periodic axial load (the axial load consists of a constant component and a periodic component). The numerical results for various load positions...
This problem is solved subject to the condition that the ratio of the impact velocity of the concentrated load to the time is non-increasing in time. The impact velocity is allowed to vary with the time. The associated problem concerning the motion of the beam following the removal of the ...
Result indicates that combined reinforcement continuous beam shows the well ability of deformation at the stress stage and the bearing capacity of the concrete continuous beam improves. 展开 关键词: combined reinforcement external pre-stress carbon fiber sheet continuous beam static load test ...
The value was evaluated from satisfying base load demand, supplying ancillary services and providing generation that is guaranteed to be available. CST holds an advantage in energy storage because, by directly storing absorbed thermal energy in molten salt tanks, TES is cheaper and more efficient ...
