This is the first of four progress reports on the column tests at the University of Illinois. The report records data on the materials used in all of the tests, and gives the results of test Series I and 2. Series I covered studies of end details of columns: (I) plane ends, with milled ends of bars flush with concrete, (2) an enlarged capital at each end of column, with bars stopped 3 in. from ends, (3) plane ends with dowels flush with ends and 20 diameter lap splices, and (4) like (3) but with 30 diameter laps. These tests showed the best results with type ( I ) and it was used in all later tests. Series 2 covered tests of columns under rapid and slow loading, with a lar e variety of grades and amounts of longitudinal l stee and four grades of concrete.
