dc.description.abstract | one of the main reasons that hinder more utilization of combustible material, such as wood, as the
primary construction material in tall buildings is the required duration a structure must withstand
applied loads under fire exposure without losing its structural integrity, which is refereed to the
fire resistance rating required by applicable building codes. however, the increased availability of
cross-laminated timber (clt) sections in canada and its successful use in mass timber
construction have generated interest in its properties and performance when subjected to fire.
floor systems in mass timber buildings can be more robust and span longer distances by adding a
top layer of concrete to form timber-concrete composite (tcc) floor systems when adequate shear
connections are utilized. the primary technique for shear connections in tcc systems is a wide
variety of metal connectors, with the self-tapping screws (sts) being one of the most used shear
connectors. therefore, proper design guidelines and methodologies are needed to determine the
accurate fire resistance of tcc floor systems. currently, there is no design procedure for the tcc
floor systems included in the canadian engineering design in wood standard (csa o86-19) but
is implemented in other international design codes, such as the european codes. [...] | en_us |
