Flexure of a Cold Formed Z-section Purlin

The Institution welcomes as its President for the Session 1970-71 Dr. 0. A. Kerensky, CBE, DSc, FRS, CEng, FIStructE, FICE, who takes office on 1 October and delivers his Presidential Address at an Ordinary Meeting at 6 pm that evening at 11 Upper Belgrave Street, London SWl.

The Council has approved the formation of two new Special Study Groups as follows:

The effect of transverse loading on a single panel square slab supported on fully composite flexible beams is considered. An elastic, small deformation analysis is made using finite difference techniques. The significant features of the results are examined and a comparison made with experimental tests on small perspex models. Some simple design rules are suggested which approximate closely to the theoretical results. M.A. Khan and K.O. Kemp
