2.6. CONTROLLED LOAD TESTING

Two static live load tests were conducted on this bridge, the first test took place before the bridge was opened for traffic and the second test was eight months after the bridge was put in-service. In both tests, a five-axle truck was used (Type 3S2 AASHTO designation), loaded roughly to full capacity in one run and to half capacity in the second; the truck and it is total weight are shown in Figure. 14.

y after detensioning. The change in strain for each gage is plotted in relation to its distance from the end of the girder in Figs. 10 and 11. The average strain is also plotted in these figures. To determine the transfer length from the measured strains, a method similar to that proposed by Oh and Kim was followed to establish the strain plateau, which was obtained by drawing a horizontal line at 95% of the maximum value of the plotted average strains. The transfer length is taken as the horizontal distance from the origin (i.e. the end of the girder) to where the horizontal line intersects t..................[:=> Show Contents <=:]

ce, is discussed in this article. The instrumentation and monitoring of a group of four girders during the process of casting operation, after construction and under the conditions and influences of traffic and thermal loads, as well as under controlled load conditions is done.The information about the parameters like transfer length, prestress loss, heat of hydration, compressive strength, modulus of elasticity, modulus of rupture, creep, shrinkage, coefficient of thermal expansion, and chloride permeability etc is measured and presented here. in-service monitoring and controlled load tests ..................[:=> Show Contents <=:]

High performance concrete (HPC) is defined as a concrete mixture which posses high workability, high strength, high modulus of elasticity, high dimensional stability, low permeability and resistance to chemical attack.
There is a little controversy between the terms “high strength concrete” and “high performance concrete”. High performance concrete is also a high strength concrete but it has a fe..................[:=> Show Contents <=:]

CONCLUSION

Mineral admixture such as fumed silica is an ideal constituent' for high performance concrete as it has the inherent ability to contribute to continued strength development through their pozzolanic / cementations reactivity and to enhance durability and chemical resistance through their pore refinement and reduced sorptivity cha..................[:=> Show Contents <=:]
