Abstract
In this investigation, an experimental study has been conducted to study the behavior of punching stress of slab column connections by using hybrid mixture when subjected to static concentric loads applied through column stub until failure after it exposed to elevated temperature. An experimental program consisted of twenty simply supported reinforced concrete slabs have been tested. The specimens have been divided into nine groups according to the studied variables. The test variables were the amound of main reinforcement, type of shear reinforcement, column location, temperature duration, reinforcement value, fighting procedure, slab thickness, and mixtures type
