Fermion compositeness, and other types of new physics that can be described by the exchange of very massive particles, can manifest themselves as the result of an effective four-fermion contact interaction. In the case of the processes e+e− → μ+μ−, τ+τ−, b̄b and c̄c at future e+e− colliders with √s = 0.5 − 1 TeV, we examine the sensitivity to four-fermion contact interactions of two new integrate...

Abstract The jointless bridges includes integral bridges, semi-integral and extended deck bridges. adopts an abutment, its main girder, abutment pile under are fixed together to bear the force together. expansion joint device cancelled, integrity, durability driving comfort of bridge improved. In this paper, a simply supported girder in Fujian Province China is taken as research background, it ...

Due to structural degradation, the performance of concrete bridges may degrade with time and result in catastrophic consequences. A novel approach is developed for evaluating time-variant reliability multi-girder considering effects load-carrying mechanism redundancy. By three failure modes at both component system levels, a new indicator proposed quantitatively load elastic distribution plasti...

The structural system of prestressed concrete (PC) voided slab deck is intermediate between plate and girder. Therefore, the conventional design method is based on the assumption that the system is similar to the plate system or to the grid system. In this paper, the structural behavior of a continuous PC voided slab deck with three spans was analyzed by using the three dimensional solid finite...

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...

Abstract: Aerodynamic admittance is a key parameter affecting the analysis accuracy of the bridge buffeting response. However, few articles have covered the issue of the wide-body flat box girder with much smaller depth-width ratio (such as 1/12 studied in this paper). Therefore, to explore the real buffeting force of the wide-body flat box girder, experiments of the static force coefficients a...
