Effect of unprotected interior beams on membrane behaviour of composite floor systems in fire, I : experimental investigation

A number of previous studies on tensile membrane action have been conducted and they are very valuable towards understanding the behaviour of isolated slabs as well as of floor assemblies. However, the role of unprotected interior beams in the development of TMA still has not clearly determined. Th...
