Dr. Neil Jackson (Queen's College, Dundee) writes:-
'Dr. Imegwu's analytical approach is a useful contribution but his method requires further clarification if incorrect solutions are to be clearly recognized. Dr. Imegwu has commented briefly on this in section 8 of his paper.'
Dr. Lenczner said, in introducing his paper, that in practice the problem of finding an appropriate value for the constant K1 could be a difficult one and at the time the paper had been written he could see no easy solution to it. Since then, however, it had occurred to him that, provided one could establish a correct value for Janssen’s
K in the static condition one could use it to obtain K1, since there was a simple relation between them which could be obtained as follows.
The paper describes an approximate method for the direct stress analysis of orthotropic skew bridge slabs, without the usual need for intermediate deflexion calculations.
