Overview

Cristián Maluk joined The University of Queensland in 2015 as Lecturer of Civil Engineering. His background is in structural fire engineering and in the broader scope of fire safety science. His research interests are in the fire performance of building construction materials and the resilience of structural systems during and after fire. Cristian has coordinated and contribute towards research studies in the fire safe design of structural concrete systems prestressed with fibre reinforced polymer tendons, heat-induced concrete spalling, performance of intumescent coatings under non-standard heating regimes, and developing novel fire testing methods.

  • Spalling during or after fire, occurs when the exposed surface of heated concrete flakes away in a sudden and violent manner. The propensity for fire-induced concrete spalling presents a serious concern in the context of the historical approach to fire safe design of concrete structures, where engineers typically rely on concrete’s inherent fire safety characteristics (e.g. non-combustibility, non-flammability, high thermal inertia).

    This project aims at investigating the occurrence of fire-induced concrete spalling and its effects in the structural fire performance of concrete structures (building or tunnel applications). This project will experimentally investigate the occurrence of fire-induced concrete spalling and propose simple, rather than complex, design methods to incorporate the risk of spalling in the design of fire safe concrete structures. The project will also propose design methods (analytical or numerical) for incorporating the effects of spalling on the load-bearing capacity of concrete structures during and after fire.

  • Conventional load-bearing floor systems consisting of cross laminated timber (CLT) panels that span between shear walls at the core of floor-plans, spandrel beams, and columns have restricted span capacities (fire or serviceability). The principles of floor timber systems replicate those of a traditional reinforced concrete flat plate systems where the ends of the floor panels are restrained from rotation by walls and column. Regarding structural fire performance, there are key gaps on how timber floor panels behave during or after fire. Fire-induced failure mechanisms of CLT systems are induced by reduction of the members’ cross section (charring and/or delamination) or weakening of the connecting conditions.

    This project aims at investigating the fire performance of floor timber systems and proposing a prototype CLT composite floor system with enhanced structural load-bearing capacity during and after fire. This project will study the potential of novel timber floor systems with enhanced fire performance. This will be done by introducing elements that allow for improved composite action of the structural system; e.g. additional anchoring to improve connection performance during fire, lamellas of material with higher residual capacity to compensate strength loss due to charring of timber.
