Eriksson has substantial experience in the area of technical publishing. Services offered include technical editing, user manual creation, creation of engineering design examples, copy editing, drafting, technical drawing, website design, pre-press work, and camera-ready artwork creation. Recent examples include:
These included a simple-span non-composite box beam, a simple-span composite bulb-tee, a three-span continuous bulb tee, and a precast stay-in-place deck slab. Each of these examples is presented in a step-by-step fashion with respect to both the AASHTO Standard Specifications and the AASHTO LRFD Specifications. Due to the large number changes to the LRFD Specifications since the BDM was first released, substantial revisions to the design examples became necessary to bring them into conformance with the current editions of the AASHTO Specifications. Because of our unique qualifications, Eriksson Technologies was hired to assess the revisions to the AASHTO Specs, review the errata that had been reported, and make all necessary revisions to the publication. This work was successfully completed in 2003.
Covers all aspects of integral precast/prestressed concrete bridges. Edited technical content, checked design calculations, laid out manual, created final artwork, and produced camera-ready material for publication.
Our training unit specializes in creating, planning, and delivering state-of-the-art training for virtually all areas of bridge design. To date, Eriksson has trained hundreds of practicing bridge engineers throughout the United States in LRFD methodologies. Our www.LRFD.com website is uniquely suited to serve as a central resource in support of our LRFD training. Eriksson Technologies continually strives to provide the highest quality technical products and training available. In pursuit of this high standard of excellence, we are committed to exceeding each state board of professional engineers' standard of care for rendering continuing education to engineers. We are authorized to issue continuing education units (CEUs) and professional development hours (PDHs) in many states. Where state oversight boards have formal certification procedures for continuing education providers, we have applied for and been certified as approved providers.
Developed, sponsored, and participated in comprehensive course for the design of concrete bridges. Topics covered included: loads, superstructure analysis, substructure analysis, girder design, deck design, pier and column design, and foundation design. Course was conducted in Tampa; Atlanta; Newark, NJ; Springfield, IL; Portland, OR; Sacramento, CA; and Irvine, CA from March 2004 through April, 2005. Several hundred practicing bridge engineers in private and public practice attended the course.
Developed course material and taught Concrete Bridges I & II modules (7 hrs total) covering LRFD principles, bridge superstructure design, substructure design, strut-and-tie modeling, and integral bridge design. Part of 4-day seminar sponsored by Michael Baker Engineers for the WV DOT, FHWA, and consultants, August 1-4, 2000, Charleston, WV.
Taught 3 hours covering design optimization, LRFD, and superstructure design. Sponsored by Prestressed Concrete Producers of Arkansas, Little Rock, AR, August 8, 2000.
Developed presentation material for, and participated in the presentation of, a half-day concrete module for a series of 2-day, intensive seminars sponsored by the Florida DOT and Florida Institute of Consulting Engineers, August-October, 1997. The purpose of the seminars was to prepare Florida bridge engineers for statewide adoption of LRFD.
Co-presenter of a half-day design seminar on new AASHTO LRFD Specification, 1995 International Bridge Conference, Pittsburgh, Pennsylvania, June 20, 1995.
Eriksson Technologies serve as a link between engineers and scientists conducting pure research and practicing bridge engineers. Our typical role in a research project is to facilitate the transfer of technology transfer to the bridge engineering community. Our knowledge of the activities and methodologies of the research community and our strong connections to practicing bridge engineers uniquely qualifies us to serve as a bridge between the two groups. Our efforts in this regard help ensure that the results of research projects have the best chance of becoming integrated into standard engineering practice. Examples of our role in this capacity include:
Developed standard drawings and model calculations for Pennsylvania DOT for standardizing the use of spliced girders in the state of Pennsylvania.
"Design and Construction Guidelines for Long-Span Decked Precast, Prestressed Concrete Girder (DPPCG) Bridges". Eriksson served as Co-Principal Investigator on this project. Total project budget is $500,000. Completed in 2010. Phase I has been successfully completed and Phase II is well underway. Eriksson’s role in the project is to: perform literature search related to design and analysis methods of DPPCG, refine/revise design and analysis methods with respect to research conducted, draft specifications language, and develop design examples.
"Evaluation of CIP Reinforced Joints for Full-Depth Precast Concrete Bridge Decks". Eriksson serves as a primary consultant on this $500k project. Areas of responsibility include: review of design procedures, preparation of design examples, review of specification language. Project was completed in 2011.
