Besides the effectiveness and accuracy of the developed method, a significant advantage is that the displacements as well as the stress resultants are computed at any cross-section of the beam using the respective integral representations as mathematical formulae. All basic equations are formulated ...

The design formula is given in Eq. (7a): Ultimate axial strength: Pu=0.85fc′Ac+fyAs Conclusions The maximum and equivalent concrete stresses that can be developed in RC members under the effect of a strain gradient were studied by the values of k3 and α respectively in this experimental...
When the neutral axis is situated on the upper flange of the H-beam, it is assumed that the stress on the upper flange of the section steel is zero. Based on the stress balance of the cross-section, Eqs. (1) and (2) are simplified, and the calculation formula for the relative heigh...
ZhouJianmin studied the distribution of crack and proposed a simplified formula on the basis of the short term deformation of high strength reinforced concrete beam [4~5]; HuangWei proposed a design formula of its resisting shear bearing capacity under concentrated load [6]; GeWenjie studied the...

The thickness averaged moment and shear components of the forces are then defined in terms of the stress as(11)(12)Summation over repeated indices is implied throughout unless otherwise stated. Green׳s function associated with Eq. (2) satisfies the radiation condition and the governing partial...
It was found that this formula is in a good agreement with the average stress calculated based on the experimental results when failure was similar to FRP-strengthened beams.doi:10.1016/j.conbuildmat.2017.05.023Raoof, Saad MUniv NottinghamKoutas, Lampros N...
The bending stresses in the panel and the tension force in the membrane tie are typically related by the formula: M=T×H where M is the bending moment at any point in the panel at height H above the membrane tie and T is the tensile force in the membrane tie, providing there is ...
