PIN-ENDED COMPOSITE COLUMNS BENT ABOUT THE MINOR AXIS
The results are presented of a theoretical and experimental investigation at the University of Sydney into the behaviour of pin-ended composite columns bent about the minor axis. The study also included test data from other sources embracing a wide range of variables such as size of steel section, slenderness ratio and eccentricity of loading. Good agreement exists between theoretical and observed results. It is well known that present design rules for composite columns lead to real load factors which are somewhat irrational. In particular the load carrying capacities of columns with slender steel cores are unduly conservative. Based on the results of the present study, a design procedure is developed which could be used for proportioning pin-ended columns bent about the minor axis; a design example is presented. This method results in higher load capacities and more realistic load factors as compared to those obtained from existing design procedures. (A) /TRRL/
