Abstract The box girder of the Miaoziping Bridge, a three-span prestressed concrete continuous rigid-frame bridge, suffered serious crack in its section’s web near 1/6 to 1/2 length side span and middle-span 1/4 3/4, as result 2008 Wenchuan earthquake, which also caused large lateral residual displacements at both ends span. In this study, eight strong-motion records bridge site two other (El C...

Abstract A methodology for performance assessment of prestressed concrete (PSC) girder bridge system, based on strain monitoring in limited number girders, is proposed this paper. The uses Polya urn model determining probabilities the system being different condition states with respect to loss prestress. Performability measure used describing system. state assigned from a predefined set states...

Flexural testing on two prestressed segmental ultra–high–performance concrete channels and reinforced conventional deck composite girders (PSUC–RCCD) was carried out. One made up of four segments with dry joints, the other formed one channel beam without a joint. Both them poured slab site. The mechanical behaviors girders, including whole loading process, crack pattern, failure mode were inves...

Trapezoidal prestressed unbonded retrofit (TPUR) systems have been recently developed and tested. The authors have already developed a comprehensive and accurate analytical solution for the TPUR system that takes many system parameters into account. The main aim of this paper is to develop a simplified analytical solution for predicting the behavior of metal beams that have been strengthened wi...
