چکیده

The behavior of externally prestressed composite beams under short term loading has been studied. A computer program developed originally by Oukaili to evaluate curvature is modified the deflection beam flexural load. analysis model based on deformation compatibility entire structure that allows determine full history strain and stress distribution along cross section depth, increment in external tendons .The evaluation curvatures for involves iterations computing strains vectors at each node any stage. determined using equations depended member points connection. proposed results load –deflection response are compared with experimental data taken from Auyyb's beams. For straight tendon profile average discrepancy reached 5.77%, 8.48% 5.23% corresponding 0.25, 0.5 0.75 maximum load, respectively. draped profile, analytical deflections values 15.5%, 5.8% 6.45%

Strengthening of Scaled Steel-Concrete Composite Girders and Steel Monopole Towers with CFRP

Cost-effective rehabilitation and/or strengthening of steel structures currently demanded by the telecommunications industry and transportation departments. Rehabilitation is often required due to crosssection losses resulting from corrosion damage and strengthening may be required due to changes in the use of a structure. Current strengthening techniques, have several disadvantages including t...

Effects of Temperature Variations on Precast, Prestressed Concrete Bridge Girders

The monitoring of a precast, prestressed girder bridge during fabrication and service provided the opportunity to observe temperature variations and to evaluate the accuracy of calculated strains and cambers. The use of high curing temperatures during fabrication affects the level of prestress because the strand length is fixed during the heating, the coefficients of thermal expansion of steel ...

Non - linear analysis of externally prestressed concrete beams

In an external prestressing system, there is no strain compatibility between the cable and the concrete at every cross-section, the increment of cable strain must be evaluated by taking into account the whole structure, rather than performing the calculation at each section, independently. In this study, a method for the calculation of cable strain, which is based on the deformation compatibili...
