Vývoj pokročilého numerického modelu kruhových ocelobetonových sloupů s rozptýlenou výztuží při požáru

Original language description

Using of concrete filled steel tube columns combines main advantages of both materials and brings economically efficient design for building structures. Due to requirements of fire resistance there is a question of additional concrete core reinforcement or steel tube secondary protection occurs. From the latest studies in this field it is apparent that using of steel fibres in concrete core could significantly increase fire resistance of member. Even though the steel fibre concrete core usage is beneficial from fire resistance point of view common analytical design approach still does not exist. This paper describes advanced FEM model of steel and fibre reinforced concrete column development. Based on advanced FEM model the numerous of numerical experiments will be made to evaluate analytical design approach.
