structures design report 2

[asixth]

Hi guys,

I have recently been asked by my DOT to submit a structures design report with other documentation for a rural bridge structure. My question is:

What information should I include in a structures design report?

I am thinking of including magnitude of loads, load combinations, methods of analysis, performance under temperature effects etc, forces and design of members.

Has anyone ever been required to provide a report along with there design?

You should also include all your references, and what design standards you were working too.

Try not to include acronyms as nobody will have a clue what you are talking about, ie. what is a DOT?

We have to do a design report with all the analysis and design. It ia common industry practice (subsea construction)

I scribbled together a document which I use as an aide memoir. The specifics wont be of use but the format might help

What alternatives did you consider in terms of materials and layout? Why were those not selected eliminated?

corus, DOT = Department of Transportation, the folks in charge of bridges.

Normally DOT's have standard formats for these reports.

Here's a link to NYSDOT Bridge Manual

https://www.nysdot.gov/divisions/engineering/structures/manuals/bridge-manual-usc

Look at Section 3; it provides information required in a strucutres justification report. The Manual also refers to a Design Approval Document. This could be an EIS or EA

For those unfamiliar with the terms:

EIS - Environmental Impact Statement
EA - Environmental Assessment

DOT's generally follow the Federal outline.

Some DOT's use what's called TS&L Study - Type, Size & Location. They include:
Project Description
Span Arrangement
Governing Specifications
Design Method
Loading
Materials
Superstructure Types
Substructure Types
Special Considerations
Cost Estimate
Recommendation
Sketches

This is common practise in the UK for Highway Structures - see the Approval In Principle and Design Certificate section in Annexe A1 of BD2/05 for guidance :-
