The change characteristics of flexural stiffness for tested beams are analyzed, and the short-term flexural stiffness formula is derived. Results: Finally the computed values of midspan deflection for tested beams are achieved.The Open Civil Engineering JournalFei ZhaoChaohe ChenHaihao Guo...
The technique of two-scale expansions [5–8], as formulated in [1], is employed (in this case the averaging methods for homogeneous problems are not applicable [9]. It is shown that, if Poisson's ratio ν is constant, the stiffnesses of a beam may be computed from formulae derived ...
corrosion methods and corrosion rate are obtained and a theoretical calculation formula of beam flexural stiffness degradation coefficient and rebar corrosion rate is fit.Then the reliability and accuracy of the formula are verified through the new reinforced concrete test beam of accelerated corrosion ...

Determining the structural properties of a truss or beam framework is part of many introductory mechanics courses for civil mechanical engineers. Apart from analytical schemes or graphical methods such as the Cremona plan, displacements and member forces can be calculated using the direct stiffness metho...
Hello, I just have simple question regarding shear stiffness for elevated water tank, this tank is elevated on a column and this column is fix in the base my question is which formula should i use to calculate k k=3EI/L3 OR 12EI/L3 i know the the first for fix pin case and the ...

[254] proposed an active vibration control method for robot-assisted milling operations by mounting a proof-mass actuator on the beam structure, which enables control of dynamic forces on the workpiece without changing the static forces provided by the robot manipulator. The dynamic response of a ...
