Response of concrete structures to fire

Abstract

This research examines the effects of increased temperatures on the characteristics of concrete. Concrete-based constructions are typically particularly efficient in high temperatures or fire. However, because concrete is a complex substance, it changes dramatically when exposed to higher temperatures. The primary impacts of fire on concrete are loss of compressive strength and explosive spalling, which can be defined as the forceful removal of material from the concrete's surface. Although significant information has been gathered in both circumstances,more systematic research on the consequences of temperature exposure is still required. The modelling of thermomechanical phenomena has advanced. In addition, current models for mechanical and thermal properties are peer reviewed. Peer review is done for an existing model for mechanical and thermal properties for unconfined concrete.
