Additional Fire Exposure Time for the Effect of Spalling in Reinforced Concrete Columns
Springer (2023)Concrete exposed to fire can experience spalling when the pore pressure increases due to water evaporation resulting in damage to part of the concrete cross-section which causes the loss of the initial cross-sectional ... -
Ambient and fire behavior of eccentrically loaded elliptical slender concrete-filled tubular colums
Elsevier (2014-09)This paper presents the results of an experimental program carried out on slender elliptical hollow section columns filled with concrete. Given the reduced number of experimental results found in the literature on concrete ... -
Efecto del spalling sobre la resistencia a flexión biaxial de pilares de hormigón armado expuestos a fuego
Asociación Española de Ingeniería Estructural (2022)El spalling es un fenómeno que sufre el hormigón expuesto al fuego debido al aumento de presión en los poros por evaporación y donde su superficie se desconcha incluso de forma explosiva durante los primeros 30 minutos de ... -
Fire design of slim‐floor beams
Ernst & Sohn (2019)Slim‐floor beams are a well‐known and cost‐effective solution that permits a significant reduction of floor thickness, and are increasingly used in industrial and commercial buildings. Since only their lower flange is ... -
Innovative solutions for enhancing the fire resistance of slim-floor beams: Thermal experiments
Elsevier (2019-11-14)Slim-floor beams have attracted the attention of designers in the last decades, owing to their ability for supporting intermediate loads without increasing the floor thickness. However, the behaviour of this type of beams ... -
Internally fire protected composite steel-concrete slim-floor beam
Elsevier (2021-01-15)The slim-floor beam is a composite concrete-steel beam fully integrated into the floor depth that was developed at the beginning of the 1990s. This composite beam presents a very good behaviour during the fire event ... -
Protected steel columns vs partially encased columns: Fire resistance and economic considerations
Elsevier (2016)As is commonly known, resistant properties of steel columns decrease quickly with an increase in temperature. Thus, steel columns are usually surrounded with low thermal conductivity materials that protect them at high ... -
Recent developments and fire design provisions for CFST columns and slim-floor beams
Elsevier (2020-06-02)This paper summarizes the latest technical and scientific progresses on steel-concrete composite structures exposed to fire, presenting the recent research carried out on this subject and the progress of the design codes. ... -
Sectional model for the fire evaluation of reinforced concrete columns subjected to biaxial bending
Elsevier (2021-08-08)In this work a simplified model for evaluating the cross-sectional capacity of RC columns subjected to biaxial bending and fire is presented. In order to build the simplified model, a fiber based numerical model is developed ... -
Simplified proposal for the temperature field of steel-reinforced CFST columns exposed to fire
Elsevier (2022-10-26)Concrete-filled steel tubular (CFST) columns are composite sections that may contribute to reduce the environmental impact in construction through a more efficient use of resources. By embedding a steel profile inside a ...
