Stability and Safe Handling of Precast/Pretensioned Concrete Bridge Girders

With improvements in materials properties and fabrication practices, single-piece pretensioned bridge girders are becoming increasingly slender, which has resulted in an increasing number of girders that cannot be safely lifted or transported without significant post-design re-engineering and/or special attention during construction. A major objective of this webinar is to build awareness of the issues associated with the lifting, handling and hauling of precast/pretensioned concrete bridge girders. In our specialty engineering practice, we have been encountering with increasing frequency girders that require some level of special treatment before they can be safely transported. We will explain the underlying reasons for this and share with attendees the techniques we typically use to deal with them, post-design. This, we hope, will provide insight to designers on what can be done during the design stage to improve their constructability downstream.
