| Abstract | An experimental investigation of the lateral buckling behavior
of eight narrow rectangular, under-reinforced prestressed concrete beams is presented herein. The beams were all simply-supported on an effective length of 15.6 ft (187 in.) and loaded to failure with a
concentrated load at midspan.
The primary variables are the depth and breadth of the beam.
Beams with depths of 10, 16, 20, 22 and 26 inches and breadths of 1.5 and 2.25 inches were tested. The effect of the slenderness ratio Ld/b2 on the flexural capacity and mode of failure of the beams is studied in the light of the test results presented in tables, curves
and pictures. The results show that within the range of beam sizes investigated, the large Ld/b2 ratios did not affect the flexural capacity as well as the mode of failure of the beams. The L/b ratios of the test
beams are compared with the provisions of the British Code of Practice for Prestressed Concrete (CP 115). It is concluded that CP 115 is rather conservative and that greater L/b ratios can be used as long
as extra care in handling during erection is exercised. |
