Abstract
In order t o compare the strength c h a r a c t e r i s t i c s of a
89 x 184 beam t o several b u i l t - u p designs, test specimens
were tested i n the lab.
A t o t a l of 15 beam specimens were tested. These were 3
designs using 5 samples of each design. One design was the
38 x 89 beam, an other design was an I-beam design
constructed from 38 x 89's, and the f i n a l design used four
38 x 89's.
T h e o r e t i c a l l y these b u i l t - u p sections should have
c a r r i e d approximately the same load, but i t was found that
the loads were s u b s t a n t i a l l y lower.
