PRESTRESSED CONCRETE BEAM STANDARDS GENERAL INSTRUCTIONS


FILE NO. INSTR-1

VIRGINIA DEPARTMENT OF TRANSPORTATION

MANUAL OF THE STRUCTURE AND BRIDGE DIVISION


The prestressed concrete beam standards (PCBT-series and PCB-series) include the Virginia Prestressed Concrete Bulb-T’s (PCBT-series) as well as the AASHTO/PCI Prestressed Concrete Beams, Types II through VI (PCB-series). The PCBT standards were developed using the Bulb-T sections adopted by the Prestressed Concrete Committee for Economic Fabrication (PCEF), a joint committee of FHWA bridge engineers, mid-Atlantic State DOT engineers and precast, prestressed concrete supplies. The Bulb-T’s range from 29” in depth to 93” in depth (in 8” multiples). At this time Virginia DOT is utilizing a 7” web to allow for two rows of harped strands. See Part 2, Chapter 12, of this manual for section properties, weights, etc. and tables for selecting economic beam sizes (preliminary design). Standard sheets have been developed for both simple spans (-S after the file number) and for continuous for live load spans (-C after the file number). There is no AASHTO Type II beam for continuous spans. Refer to NOTES TO DESIGNER for specific comments on each standard sheet. Standards for diaphragms have been developed for the following: cells for cast-in-place concrete end and intermediate diaphragms for both Bulb-T’s and AASHTO/PCI beams; insertable sheets for galvanized steel intermediate diaphragms for both Bulb-T’s and AASHTO/PCI beams; closure (continuity) diaphragms for Bulb-T’s. The end and intermediate diaphragm details may be placed on the TRANSVERSE SECTION sheet if there is enough room. For the cast-in-place concrete diaphragms, the reinforcing steel details (bar designations, sizes, lengths, weights, etc.) must be added to the REINFORCING STEEL SCHEDULE under SUPERSTRUCTURE. Under LOCATION, note as END DIAPHRAGMS, INTERMEDIATE DIAPHRAGMS or CLOSURE DIAPHRAGMS. For the galvanized steel intermediate diaphragms, the steel quantities are included in price bid for prestressed concrete beams and should be so noted under the GENERAL NOTES on the title sheet of plans. Completion of the project block, title block and lower left corner shall be in accordance with the requirements of File Nos. 04.04-1 thru -2 of Part 2 of this manual and as specified herein.

If a standard sheet is modified by the designer, the letters “MOD.” (without quotes) shall be added behind the standard designation in the lower left portion of the border, e.g., PCBT-29S MOD. Completing items on the standard that are indicated in the NOTES TO DESIGNER are not considered to be modifications. Minor modifications do not require approval (except for those proposed by Concessionaire/Design-Builder where emailed approval by the District Structure and Bridge Engineer documented to the project design file is required for any modification). See Part 1, Section Pre.02 of this manual for definition of minor modification. Modifications not considered minor as defined in Part 1, Section Pre.02 of this manual require email approval by the District Structure and Bridge Engineer documented to the project design file unless a design exception is required. In general, in the title block (lower right hand corner of sheet) Designed, Drawn and Checked are blank and need to be filled in with the appropriate initials. For standard sheets without any design or detailing requirements, Designed, Drawn and Checked are filled in with “S&B DIV.” If the design or details are modified, these fields should be filled in with initials as appropriate.

The CADD standard beam detail sheets are located in Falcon […\PROJECTS\br-stand\sbr\pcb] directory (central office environment). The drawing file name for the standard sheet corresponds with the file number (name of standard sheet) as listed in the Table of Contents (minus the dash). For example, standard PCBT-29C is drawing pcbt29c.dgn. A cell library (pcb.cel) is included with the standards to allow the designer to modify/replace details on the standard sheets. The PCBCELLS sheets included herein depict the cells found in the cell library along with the name of the cell, an image of the cell, a description of the cell and the origin of cell. The origin of cell is indicated by a star . For department staff to attach the cell library, use the pull down menu in MicroStation under ELEMENT – CELLS and select FILE to get a drop-down listing of available cell libraries. For external users, the cell library is included as an attachment to this file. Click on the attachment tab.

For external users, the CADD standard detail sheets are attached to the PDF files for each drawing located on VDOT’s Structure and Bridge Division website. The user will need Adobe Reader version 7.0 or higher to be able to access the files. Either click on the DGN link in the table of contents or click on the attachment tab in the PDF file for each standard sheet.

Using either method, the screen will appear similar to that shown below.

Full manual no links If the printer has both 8 ½ x 11 and 11 x 17 paper sizes available, the drawings and notes to designer may be printed on the correct paper size by placing a check next to the item “Choose Paper Source by PDF page size” as shown in the dialog below:

If the printer only has 8 ½ x 11 paper, the drawings will default to the reduced paper size. Depending on the printer margins, the 11 x 17 drawing(s) may not be true half-size drawing(s).
