Design Guide 4

For structural hollow section columns exposed to fire



This guide is the fourth in the set of works by the CIDECT under the general title "Construction with Hollow Steel Sections". It is dedicated to fire protection of columns in hollow profiles exposed to fire. One of the major advantages of columns in hollow profiles is to give possible protection against fire without resorting to the addition of classic materials on the external faces of the profiles.

In filling the hollow profiles with water or concrete, not only does it allow the reduction of clutter of the columns but one also obtains a cleaner and more elegant solution.

The three types of fire protection - external protection with insulating materials or special paints, water cooling, statically or with circulation, and filling with concrete - are described in this book, that contains many examples permitting a better understanding of the topic.
