Abstract

Reinforced concrete structures are typically considered to have inherent resistance to fire. However, several concrete structures around the world have experienced partial or total collapse under fire. Reinforced concrete flat-plate is a type of structural system widely used for office and residential buildings. Flat plate construction is prone to punching shear failure at slab-column connections which may lead to a catastrophic progressive collapse. The slabs of flat-plates generally have very thin concrete cover leaving steel reinforcement more sensitive to thermal loads. Little is known in the engineering community about the structural performance of flat-plate structures subjected to fire. Through a detailed nonlinear finite element analysis, this study will examine the internal force and deformation redistribution characteristics of flat-plate structure under fire. Insights gained from this study will create knowledge needed to improve fire-resistant design of flat-plate buildings.
