Correspondence on A Simplified Method for Evaluating the Natural Frequencies and Corresponding Modal

This paper deals with the various factors that affect the racking resistance of timber framed panels. The principal factors are the sheathing materials, the extent of vertical loading, the length of the panel, openings, holding down and the nail spacing. Other factors are generally of lesser importance. Test results relating to these factors are analysed, and a relationship is derived for each factor. The effects of outer claddings and inner linihgs are discussed very briefly. A simple design method for calculating the allowable racking resistance of panel assemblies is suggested. R.A. Robertson and D.R. Griffiths

Niamh McCloskey reflects on her personal experience of the challenging reality of returning to work after maternity leave, questioning whether workplaces truly support women in this transition and highlighting how, with the right support and recognition of the new perspectives and skills that motherhood can bring, we can retain mothers and allow them to thrive in underrepresented industries.
