Excerpt from Tests of Large Columns With H-Shaped Sections The Bureau of Standards, in cooperation with the American Bridge co. Undertook, therefore, a study of a limited number (39) of larger columns, here called the first series, designedto compare the behaviors Of light and heavy columns of similar cross section. It was further desired to compare the strengths of riveted' columns fabricated in the ordinary manner Of plates and angles with similar solid rolled sections of the same section area, radius of gyration, length, and Of similar material As the previous tests had indicated that the properties of the steel influenced in a large degree the be havior of the columns, a series of 85 tensile test coupons were cut from the material of the columns and tested for yield point (by drop of beam), tensile strength and elongation, and) chemical analyses: were made from each coupon. Later 42 supplementary coupons were cut from some of the material and tested. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
