czbk751225@qq.com,dleepo@163.com Keywords: high-strength steel; concrete simply supported beam; flexural performance; Abstract: In order to study the flexural performance of high strength reinforced concrete beam, through the loading test of six groups of specimens, investigate its force deformation...
aThe bending moment diagram for such a beam can be considered to consist of two parts, namely the free (bending) moment diagram obtained by treating the beam as if the ends are simply supported and the fixing (moment) diagram resulting from the restraints imposed at the ends of the beam. ...
moment-curvature relationship program,the elastic-plastic seismic responses of a high-speed railway bridge under different earthquake intensities and effect combinations were calculated considering different train speeds and soil-structure interactions(SSI).The calculation results showed that the influence of...

The proposed method can transform the calculation of dynamic bending moment and curvature into an equivalent static calculation to formulate a straightforward algorithm and easy-to-use equation on section flexural rigidity. It is applicable to non-uniform simply supported beams with arbitrary stiffness ...
