In the past decade, with a growing interest in long span bridge girders, designers are using
an increasing number of prestressing strands. This scaling up has led to cracking issues in …

As a result of heavy prestressing, anchorage zones of bridge girders frequently crack in
consistent patterns at prestress transfer and cause durability concerns. These cracks, which …

Ultra-high performance concrete (UHPC) has gained popularity gradually because of its
superior mechanical properties, including high compressive and tensile strengths, and …

The design of end zones to prevent severe cracking is a key requirement toward durable
prestressed girders. Traditional approaches employ large amounts of steel reinforcement to …

The use of 18-mm prestressing strands is advantageous in the construction of long-span
bridges. Transmission length is a significant parameter in the design of pretensioned …

Many research initiatives over the last two decades have had the objective of increasing the
available spans of prestressed concrete bridge girders and have resulted in optimized cross …

■ The field monitoring was conducted during prestress release on 72 in.(1829 mm) deep
concrete bulb-tee bridge girders with 0% and 25% debonding ratios and 54 in.(1372 mm) …

Prestressed concrete I-girders are becoming more widely used in bridges. However, the
high prestressing force applied to these girders can lead to cracks in the end zone upon …

The rapid growth of 3D printing technology has led to the development of large scale 3D
printers that can print in concrete and steel. The process of 3D printing in concrete does not …

Validity of the approximate equation for predicting compressive stress in the posttensioned
anchorage zone presented in the AASHTO LRFD Bridge Design Specifications was …
