Shear Experiments of Prestressed Concrete Bridge Girders

In addition, the results show that for prestressed concrete girders, the influence of the shear span-depth ratio should be considered for shear span-depth ratios larger than 2.5. These insights can be used for the assessment of existing slab-between-girder bridges in the Netherlands. Subject. bridge assessment shear-tension shear-compression shear

Monitoring Shear Behavior of Prestressed Concrete Bridge

2020-10-1  In the Netherlands, many prestressed concrete bridge girders are found to have insufficient shear-tension capacity. We tested four girders taken from a demolished bridge and instrumented these with traditional displacement sensors and acoustic emission (AE) sensors, and used cameras for digital image correlation (DIC).

Anchorage-controlled shear capacity of prestressed

The results of this research are an important step towards improving understanding of strand anchorage related issues. For the experimental program, two full-scale Tx46 prestressed concrete bridge girders were fabricated at FSEL. The Tx46 girders were topped with a concrete, composite deck. Both ends of the two girders were instrumented and tested.

Shear Cracking of Prestressed Girders with High Strength

2013-3-29  Prestressed concrete (PC) is the predominant material in highway bridge construction. The use of high-strength concrete has gained wide acceptance in the PC industry. The main target in the highway industry is to increase the durability and the life-span of bridges. Cracking of elements is one aspect which affects durability. Recently, nine 7.62 meter long PC

Prestressed Concrete Bridge - an overview ScienceDirect

The prestressed concrete bridge girder shown in Fig. 6.9 spans 21.6 m and supports a superimposed dead load G of 6 kN/m and a live load Q of 20 kN/m (excluding self-weight). A 150-mm thick topping slab was cast over the top flange of the beams after full stressing. The bridge is upgraded for HLPV resulting in an increase in the unfactored live loads applied to the beam.

Nontraditional Shear Failures in Bulb-T Prestressed

An experimental study was conducted in which five identical, full-scale bulb-T bridge girders were constructed and tested to shear failure. Although the shear span was kept the same for all of the tests (a = 3d), the distance from the end of the specimen to the center of the support bearing (overhang length) was varied.Varying the overhang length controlled whether or not the critical

Residual Prestress Forces and Shear Capacity of Salvaged

Seven prestressed concrete bridge girders that had been in service for 42 years, and represented two span lengths and reinforcement designs, were tested to determine their effective prestress force and ultimate shear capacity. A cracking moment test was used to determine the effective prestress force in the girders.

Shear Experiments of Prestressed Concrete Bridge Girders

For the assessment of existing slab-between-girder bridges, the shear capacity and failure mode are under discussion. Previous research showed that the static and fatigue punching capacity of the slabs is sufficient as a result of compressive membrane action. The girders then become the critical elements. This research studies the shear capacity of prestressed concrete bridge girders.
