FRACTURE AND FATIGUE CONTROL IN STEEL STRUCTURES

The procedure is described and the results are presented of tests (residual stress measurements, coupon tests, compression tests of columns, tension tests of columns) conducted on W14 x 176 shapes of A36 material. The results indicate that the lack of perfect contact at compression splices of columns may not be important, provided that gaps are shimmed and welding is used to maintain the sections in alignment. It is noted that the spliced columns, rather independently of the gaps introduced at mid-height, behaved very much like the unspliced column and their column strengths were essentially the same. The Kl/r ratio of the columns tested was low, (about 30). It is noted that columns and braces in buildings, as well as in offshore structures, may buckle in compression under extreme excitation and then become subjected to tensile forces.
