Web-face sheet junction

Analyzing the failure mechanism (delamination between webs and face sheet close to the support) and based on [17], it was concluded that ultimate failure was initiated by a shear failure at the web-face sheet junction. In fact, delamination initiated at a distance of 300 mm from the support, that is, at the location of maximum shear force within the fire-exposed region. The web-face sheet junction, furthermore, is the critical location in this critical cross section because ...
