Need old beam properties--fast!

Need old beam properties--fast!

Need old beam properties--fast!

(OP)
Need properties for analysis of the following beams  (I believe they were installed around 1956):

27WF62

30WF116

Any help would be greatly appreciated.

RE: Need old beam properties--fast!

30WF116:  A=34.1in2, Sx=327.9in3, Ix=4919in4
Don't make a 27WF62 how about a 21WF62?

ronster-

Could you give me the source of this information?  No 27WF62 for circa 1956?  Are you sure?  This is the shape listed on the drawings in numerous places.  I may have to try to field verify the depth if I can get to it.

RE: Need old beam properties--fast!

See the FAQ section for a reference to old beams and their properties.

RE: Need old beam properties--fast!

AISC Manual,5th Ed, 1951

21WF62
A=18.23,d=20.99,FW=8.240,Ft=0.615,Web t=0.400,Ix=1326.8,Sx=126.4,rx=8.53,Iy=53.1,Sy=12.9,ry=1.71

Lightest 27 in. beam is 27WF94

RE: Need old beam properties--fast!

We have a book here at work entitled "Iron and Steel Beams 1873 to 1952" published by AISC which lists the following:

30WF116: Area=34.13, depth=30.000, flange width=10.500, web thick.=.564, m & n ave thick.=.850, R=.65, % slope of inside flange=5, Ixx=4919.1, Sxx=327.9, rx=12.00, Iyy=153.2, Syy=29.2, ry=2.12

They also list another section with all of the same properties except R=.70 and inside flange slope = 0.

No 27WF62's are listed.  Sorry, good luck.  

RE: Need old beam properties--fast!

CISC Handbook for 1962 has W27x84 as lightest for rolled WF shape (W Shape) and W27x74.2 for Welded Plate Girders.

RE: Need old beam properties--fast!

If you go to the Bethlehem Steel web site and look under archives you will find a heap of documented info in .pdf format. I had a quick look for you and the W30x116 is there and the W27x62 is not, W27x84 is the smallest but I only had a quick look. There is a lot of stuff there so have a look yourself you might find it. Hope this helps.

RE: Need old beam properties--fast!

That's good information to know Blueprint.  You should put that into a FAQ for all to see.  I'm glad that there is another source out there other than the old AISC book which is darn hard to get a hold of these days.
