This paper focuses on Load distribution factors for horizontally curved composite concrete-steel girder bridges. The finite-element analysis software“SAP2000” is used to examine the key parameters that can influence steelgirders. A parametric study conducted load characteristics of such bridge system due dead loading and AASHTO truck using finite elements method. considered in this are: span-to...

Because of their tensile strain-hardening characteristics, ultrahigh-performance concrete (UHPC) materials offer significant advantages in terms beam shear capacity and postcracking behavior compared to conventional reinforced-concrete beams. These rely on UHPC’s ability sustain its characteristics at the structural level. This paper reports results an experimental investigation parameters infl...

SPring8 storage ring is 8GeV synchrotron radiation source, which circumference is 1436m with 48 double-bend achromatic cells. This ring has also four long straight sections. Before modification three girders were put as other section. A long undulator (27m) was installed at one straight section and three free spaces were made at other sections in the summer of 2000 as shown in Fig.1. This modif...
