Dead and Live Loads

Clearly a complex subject, is there any possibility that someone could provide details for calculating D&L Loads @ Higher Education Level. I have an understanding of the principals, but not of how to calculate the D&L Loads on a pitched roof for example. Cheers {unsigned|Ceej18|15:04, 16 January 2006}

The loads are really no more complicated than A-Level Mechanics - your example of a pitched roof is especially easy. Dead would be self weight which you would be given (or at least the means to calculate it) applied vertically down...Live load would be the wind, snow and rain (+ any others as specified by BS) the values of which are given in Standards, eg if the BS say a pressure of 0.004N/mm needs to be added for wind you would either apply it directly if using FEA program or work out the force by F = PA.

Blihps revision was incorrect - imposed loads are not human induced loads, infact very few situations are human induced...see the loads discussion page. For this reason and the break up of continuity I have reverted to the older version - Sam Lacey 01:38, 6 September 2006 (UTC)

Proposed edits

I would like to revise this page to: (a) remove the UK-centrism and focus on staircases (b) introduce more up-to-date terminology e.g. the Eurocode use of terms such as "permanent actions" and "variable actions" If anyone has any view, please post here before I make what may be quite significant changes!

I would agree with globalising this page and if you think you can convey the examples without using staircases (I picked them as examples because I considered them complex enough to get the points across but familiar enough to not be daunting) then you are welcome to have a crack. As for the terminology if you feel the need to change it knock yourself out but I chose those over their synonyms for their comparability to other laymans terms. Personally I dont think i went deep enough into the actual Mechanics of loading and barely mentioned bending moments and inertia etc which I would like to change at some point when I can find the damned time Sam Lacey 11:02, 7 November 2006 (UTC)

There seems to me to be a contradiction in the wind loads. At first it is stated that the wind is a live load then later it is stated it is not a live load. I'm almost certain (at least in the US) that wind is not considered a live load but someone else should confirm this.

Wind load is absolutely in every country in the world considered a live load. 110% Sam Lacey ( talk) 03:15, 11 January 2009 (UTC) reply

The math in the last section is completely wrong. FYI. —Preceding unsigned comment added by 71.230.41.168 ( talk) 18:07, 31 January 2011 (UTC) reply

Merge and redirect

Merged the sections on "Dead loads" and "Live loads" to the corresponding sections in Structural load. The sections on "Real World Usage" and "Calculating Combined loads" were copied over but then heavily edited and merged into other sections. The Structural loads page should be in the wikiproject for civil engineering, instead of this page, but I don't know how to fix that. -- Panchobook ( talk) 21:27, 25 June 2011 (UTC) reply

Two problems. One, there was no Consensus for this. Two, you missed a lot of key information in the article you deleted. Please make correctios. Please follow Wikipedia rules. Pkgx ( talk) 17:20, 27 June 2011 (UTC) reply
There was no opposition to the proposal so I see no problem in the merge. For your second point - what key information was missed? Unless you can be specific it will be difficult to fix it. noq ( talk) 17:24, 27 June 2011 (UTC) reply
Pkgx, I'll be happy to add to Structural loads any key information that I missed. Can you please point out what is this missing key information? -- Panchobook ( talk) 20:51, 27 June 2011 (UTC) reply
