Title

A STUDY AND ANALYSIS OF THE BEHAVIOR OF PRESTRESSED CONCRETE BRIDGES WITH DIAPHRAGMS


Abstract

Accelerated Bridge Construction (ABC) has increased generous notoriety in new scaffold development and extension deck substitution since it offers imaginative development strategies that bring about time and cost reserve funds when contrasted with conventional extension development practice. One innovation usually actualized in ABC to successfully execute its undertakings is the utilization of pre-assembled connect parts (precast/prestressed connect segments). Precast/prestressed connect segments are manufactured offsite or close to the site and afterward associated nearby utilizing little volume conclusion pour associations. Stomachs are additionally generally used to reinforce the association between certain pre-assembled segments utilized in ABC, for example, bar components. Scaffolds containing conclusion pour associations and stomachs can be structured utilizing AASHTO LRFD live-load dispersion factor recipes under the condition that the extension must be adequately associated. Be that as it may, these equations were created utilizing expository models that didn't represent the impacts of conclusion pours and stomachs on live-load dispersion. This exploration study researches live-load dissemination attributes of precast/prestressed solid scaffolds with conclusion pour associations and stomachs. The examination was directed utilizing limited component connect models with conclusion pour joints that were adjusted utilizing exploratory information and diverse design of stomachs. The solid material utilized for the conclusion pour associations was created as a major aspect of a bigger task expected to grow high early-quality solid blends that explicitly arrive at quality in just 12 hours, a basic necessity for ABC ventures until a focal edge of 38º which is somewhat out of as far as possible.
