Dimensions of obsolete beams 2

I am not aware of an online source.&nbsp;&nbsp;This forum is probably your free source.&nbsp;&nbsp;The American Institute of Steel Construction (AISC) has published an historical record of dimensions and properties of rolled shapes.&nbsp;&nbsp;The book is titled &quot;Iron and Steel Beams 1873 to 1952&quot;.<br><br>The following editions of the AISC Steel Manual contain the 6B12.<br><br>2nd ed. 1934<br>4th ed. 1941<br>5th ed. 1947<br>6th ed. 1963<br><br>It probably is also in the 3rd edition, but I don't have a copy.<br><br>The properties are:<br><br>Depth 6.00 in<br>Width 4.00 in<br>Area&nbsp;&nbsp;3.53 in^2<br>Flange thk 0.279 in<br>Web&nbsp;&nbsp;&nbsp;&nbsp;thk 0.230 in<br>Weight 12 lbs/ft<br>Ixx 21.7 in^4<br>Sxx 7.24 in^3<br>rxx 2.48 in<br>Iyy 2.89 in^4<br>Syy 1.44 in^3<br>ryy 0.90 in<br><br>There is a Wide Flange beam (W6x12) with very close properties in<br><br>7th ed. 1970<br>8th ed. 1980<br>9th ed. 1989<br><br>Thru the 5th edition, Structural steel was A7 (yield 33ksi).&nbsp;&nbsp;The 6th edition recognized the use of A36 (yield 36ksi).<br><br>A good source for out of print books is: <A HREF=" TARGET="_new">

Thanks for the tip. I was hoping that old data might be available on-line somewhere. I guess I'll have to bite the bullet and order from AISC.<br>Thanks again.<br>David Anderson

You may want to check the used book dealers on the web for a copy of one of the older AISC Steel Construction Manuals.&nbsp;&nbsp;I have three old ones I got at tag sales over the years and once in a while they come in handy. <br><br>Try the site listed below.<br><br><A HREF=" TARGET="_new">

It seems like you got the answer.&nbsp;&nbsp;Why do you have to buy yhe book?<br>
