The recently developed smart strand offers the possibility of measuring the prestress force of the tendon from jacking and all along its service life. In the present study, a method estimating the force distribution in all the tendons of a prestressed con... see more

ResumenEl hormigón pretensado reforzado con fibras, presenta simultáneamente las ventajas de los hormigones pretensados y de los reforzados con fibras. Se consigue un material de altas prestaciones en cuanto a su tenacidad, ductilidad y resistencia a la t... see more

A relatively simple technique has been introduced in this paper. The approach is based on the Linear Force Method (FM) with discretion of the applied loads to the subsequence steps and updating coordinates in each iteration to have new geometrical propert... see more

In this paper, we present an analytical model to analyze reinforced and prestressed concrete beams loaded in combined bending, axial load and shear, in the frame of non linear elasticity. In this model, the equilibrium of the beam is expressed by solving ... see more

ASPECTS ABOUT THE NUMERICAL MODELING OF THREE-DIMENSIONAL PRESTRESSED STEEL-CONCRETE COMPOSITE BEAMS BY USING THE FINITE ELEMENT (FE) METHOD ARE HIGHLIGHTED AND COMMENTED IN THIS WORK. EMPHASIS IS GIVEN TO THE NUMERICAL TREATMENT OF BONDED AND UNBONDED TE... see more

Time dependent variables such as temperature gradient, effective temperature, creep, and shrinkage lead to long term deflection in prestressed concrete girders. This in turn effects the serviceability and sustainability of the bridge in the long run. Ther... see more

The economy of a prestressed steel beam can be realized only when relevant parameters of optimum magnitude are chosen. The present work aims at finding out the optimum dimensions of a simply supported, laterally unsupported, prestressed steel I-beam for a... see more

The operational features of prestressed resilient elastic threads under the influence of lateral point forces have been estimated.
