Burr, William H. (William Hubert), 1851-1934 · New York, J. Wiley & sons · leaf 470
ct. 1880, aregiven the following formulae for ultimate resistance of wrought-iron columns, designed several years since by C. Shaler Smith,C.E.: • Square Cohimn, / = FLAT ENDS.38500 I + 5820 d^ / = ONE PIN END.38500 I + I I 3000 d^ P = TWO PIN ENDS. 375QOI 1900 d^ I +—-3-, Phcenix Column, 42500 I +… … P 36500 ^^^A /- 36500 2700 d I + I P 36500 1500 d^ I + 7—:-r. 1200 d The formula for square columns may be used, withoutmuch error, for the common chord section composed of twochannel bars and plates, with the axis of the pin passingthrough the centre of gravity of the cross section.
