![]() ![]() Splice connections are categorized into distinct types. Construction issues that should be considered during the concept development and design stage are highlighted. Several methods were reviewed that have been used in the past to provide continuity and increase the span length of slab-on-girder prestressed concrete bridges. Continuity connection details used for precast, prestressed concrete girder bridges across the United States were investigated. A wide variety of design and construction approaches are possible when making these precast concrete bridges continuous with longer spans. The objectives of this portion of the study are to evaluate the current state-of-the-art and practice relevant to continuous precast concrete girder bridges and recommend suitable continuity connections for use with typical Texas bridge girders. TxDOT is interested in developing additional economical design alternatives for longer span bridges, through the use of the continuous precast, pretensioned concrete bridge structures that use spliced girder technology. Abstract The Texas Department of Transportation (TxDOT) is currently designing typical highway bridge structures as simply supported using standard precast, pretensioned girders. A total of 15 chapters are published in February 2015, with more to follow.ฤก6. CRACK LIGHT IMAGE RESIZER 4.7.3.1 MANUALThe BDP conforms to the AASHTO LRFD Bridge Design Specifications (Customary US units), sixth Edition with the 2014 California Amendments, except as noted describes the basic design concepts and assumptions provides step-by-step design examples introduces innovative practice and serves as a comprehensive reference manual for Caltrans bridge design engineers. The fourth edition of the BDP is divided into three volumes and covers the major areas in bridge and highway structure design. The primary purpose of the BDP is to provide bridge design engineers with application of the California Department of Transportation (Caltrans) design standards and practices that lead to consistency in the design of bridge and highway structure projects on the California highway systems. ![]() ![]() The BDP has been published as a live document continuously since the 1990s. The first edition of the Bridge Design Practice Manual (BDP) was published in 1960, and the second and third editions were published in 19, respectively. ![]()
