Revised Truss Gusset Rating Using LF & WS Methods (May 2010)
The Office of Structural Engineering has revised the spreadsheets used to rate gusset plates located on Load Rating Downloads Page. The original file extension is xlsx, please change the extension after downloading the files. Major changes were focused in Check No. 3: Minimum Rivet Count Requirement and Check No. 7: Gusset Plate Combined Planes Shear Rupture Resistance. The formulas in Check No. 3 wre revised to calculate more accurately bearing capacities of fasteners on plates. This is to comply with AASHTO 17th Edition 10.46.1.3. Check No. 7 uses the vertical and horizontal components of axial forces of truss members, and it applies them in the appropriate gusset plane to calculate global block shear capacity. Some of these force components were reversed. While bearing stress of fasteners and global block shear seldom control load rating, it is advised to double check the results. For questions or comments, please email: Omar.Abu-Hajar@dot.state.oh.us

MEMORANDUM ON LOAD RATING OF NEW BRIDGES
All new and replacement bridges, with preliminary design starting after October 1, 2010, and requiring load rating, shall be load rated at inventory and operating levels by the AASHTO LRFR method to comply with FHWA requirements. The load to be used for inventory and operating rating based on LRFR method shall be AASHTO’s HL-93 loading (truck & lane or tandem & lane), according to BDM Figure 902.
All bridges shall also be load rated for four Ohio Legal Loads (2F1, 3F1, 4F1, and 5C1) at operating level using the same method of analysis as used for inventory and operating ratings above. The four Ohio legal loads (2F1, 3F1, 4F1 and 5C1) are given in BDM Figure 903.
All trucks used for analysis shall have transverse spacing, between centerline of wheels or wheel groups, of 6 ft. [1.830 m].
For long span bridges as defined in BDM Section 905, use the special load configurations given in BDM Section 917.
The inventory and operating ratings for the AASHTO HL-93 loading shall be expressed in terms of rating factors, rounded off to the nearest two decimal points. The operating ratings for each of the Ohio Legal Loads shall also be expressed in terms of rating factors of respective legal load rounded off to the nearest two decimal points. The summary rating for all of the Ohio Legal Loads shall be the smallest rating factor of the four vehicles expressed as a percentage (i.e., multiplied by 100) and rounded off to the nearest 5 (125%, 100%, 65%, etc.)

| 3/28/2011 | Load & Resistance Factor Rating Training
This course is meant to train bridge designers and engineers on the Load and Resistance Factor Rating (LRFR) requirements given in ODOT Bridge Design Manual (BDM), Section 900 which is based on AASHTO's Manual of Bridge Evaluation.
| Description | |
| 4/4/2011 | The deployment of the new inspection program has been pushed back one week to Monday, April 11, 2011. These applications will be affected:
BMRI New version 2.8.0.0
Will be release on Monday, April 11th following the Sunday upgrade to BMS. This new release supports the new BMS database and is incompatible with the prior version of BMRI. A conversion utility will be included within the install package to import old export databases into the new format(s). However those inspection dates after the implementation and (obviously) uploaded after the implementation will not need to use this conversion utility i.e. business as usual.
For COBOL (CEAO Software, Inspectech):
New version online and updated txt files will be available after the implementation. When inspection dates before 4/10/11are uploaded into BMS the following rules will be applied:
20. Gusset Plates - default to blank or "Space"
21. Lateral Bracing - default to blank or "Space"
48. Scour (left box) - default to blank or "Space", and remove the error code
49. Abutments - default to blank or "Space"
69. Default the new Survey Boxes (5, 6, 7 & 8) to "N"
BMS
New version will be available and it will only show the new inspection form after the implementation. For bridges inspected before 4/10/11 and uploaded after this date inspectors will have to use the new format and they should use the default values (stated above) for the eight boxes that have changed definitions.
Preprints will follow a similar format as the BMSWebreports but without a username and password and with more batch-printing capabilities.

Development of the Steel Bridge Handbook was funded from the SAFETEA-LU Higher Performing Steel Bridges designated program. This handbook covers a full range of topics and design examples to provide bridge engineers and owners with the information needed to make knowledgeable decisions regarding the selection, design, fabrication, and construction of steel bridges. The handbook is based on the Fifth Edition, including the 2010 Interims, of the AASHTO LRFD Bridge Design Specifications. This is the culmination of seven years of effort beginning in 2005 by many recognized experts in the steel bridge industry. This Handbook may be downloaded free of charge from the attached link. | Steel Bridge Design Handbook | |

Structure Management System (SMS) stakeholders,
After discussions with the developers and ODOT staff, ODOT has made the decision to launch the new SMS in production mode “GO LIVE” the week of May 12, 2014.
The current Bridge Management System (BMS) will be switched to ‘read-only’ mode on April 3, 2014. Therefore data in the BMS will not get updated after switching to read-only mode. Any unapproved inspection reports or changes to inspection or inventory data must be submitted or made prior to April 2, 2014 in the current BMS or wait until after the new SMS goes live.
SMS Training:
- The Office of Structural Engineering will continue to provide open labs and will make video tutorials available.
- Manuals, in development, will be imbedded into the SMS.
- Future Bridge Inspection Training, also in development, will incorporate changes associated with SMS and Element Level Inspections.
For further information regarding the SMS transition, logging into the test-site, software & hardware requirements, URL of SMS in production mode and any future announcements, please refer to the following web page:

| 4/15/2022 | LEAP Bridge Concrete - Abutment Foundation Loading
While performing an abutment design in LEAP Bridge Concrete – Substructure module, with the entire bridge modeled in the software, ODOT has witnessed an overestimation of the abutment self-weight resulting in higher pile loads. The magnitude of the error is difficult to define because it is dependent on several geometric aspects of the abutment but it can be as high 10 times above the expected loading. It should be noted that this error only occurs when trying to design the abutment with the entire bridge being modeled in the software. The work around for this issue is to create a standalone design file for just the abutment and use that model to design the abutment by manually inputting the beam loads.
Bentley has been made aware of this issue and they are in the process of determining the source of the error so they can get it fixed.
