Abstract:
Structural Fire Engineering Design explicitly evaluates demand and capacity of structural systems under fire exposure. This explicit evaluation considers natural fire exposure conditions resulting from a physically based description of the fire (as opposed to a standard fire exposure). Designing structures under natural fires requires an understanding of the response of materials and structural assemblies under both the heating and cooling phases of the fire. This presents opportunities as the designer can explicitly demonstrate the ability of a structure to resist to full fire burnout or other discretionary performance objectives identified by the stakeholders in accordance with ASCE/SEI 7 Appendix E. To enable this shift in fire design of concrete structures, research work is ongoing as part of an ACI Foundation project to collect data about concrete behavior in cooling and propose design methods for burnout resistance. This presentation will describe the outcomes of the project, as well as the envisioned impact on the ACI 216 standard with respect to behavior and design of concrete structures under natural fires.
