... high temperatures significantly compromise the strength and stiffness of concrete, leading to substantial reductions in load-bearing capacity (Khoury, 2000). In construction engineering, the use of desert sand concrete (DSC) necessitates a thorough assessment of its post-fire performance, particularly...

...Suhang Yang; Liu Xiaoxin; Gonglue Gao Purpose This study investigates the synergistic degradation effects of high-temperature exposure and subsequent freeze–thaw cycles on the mechanical behavior of steel fiber-reinforced reactive powder concrete ( RPC ). It aims to quantify the residual...

... coefficients for the creep model are obtained. As a result, a behavioral model for ASTM A992 steel has been developed, which accurately predicts the performance of steel columns at high temperatures. The effect of loading rate on the stress-strain curve of steel was determined and compared with Eurocode...

...Vishal M.; Satyanarayanan K.S. Purpose This paper delineates a literature review on fire-induced progressive collapse on structures and the effect of high temperature on structures and elements. After the occurrences of fire in the World Trade Center in the USA, the researchers started...

... the index value is, the better the performance. Findings The results demonstrate that the glass-wool-concrete cover offered the best performance at high temperature among the four types of materials. In the experiment with glass-wool-concrete cover, the furnace temperature reached 750°C, whereas...

...Amir Hamzeh Keykha Purpose This study aims to investigate the effect of high temperature (600°C) on the compressive strength of concrete covered with a mixture of polypropylene fiber and gypsum plaster (PFGP). Design/methodology/approach To study the compressive strength of concrete specimens...

... shear stresses. Design/methodology/approach Three series of push-out tests at room temperature and high temperatures are analysed in terms of ultimate shear strength, bond strength and shear strength-displacement-curve shape. The test parameters involve the steel core diameter and concrete cover...

... in the Vesuvian area, which are made of timber, steel and reinforced concrete. Therefore, some protection systems for mitigating the effects of the combination of overloading and high temperatures on the examined roofing structures are identified. Explosive eruptions Vesuvian roofs ash fall deposits...

...Marija Jelcic Rukavina; Dubravka Bjegovic; Ivan Gabrijel This paper presents an experimental research on the performance of high-strength selfcompacting concrete (SCC) with different mineral additives after exposure to high temperatures of up to 600°C. For this purpose, four SCC mixtures were...

...Robert Kowalski; Michal Glowacki; Marian Abramowicz The paper presents results of experimental research whose main topic was determination of stiffness reduction in bent reinforced concrete beams in two cases: when only tensioned or only compressed zone was exposed to high temperature. Twenty four...

...Rabah Hammoud; Rachid Boukhili; Ammar Yahia A numerical model to simulate the impact of high temperature on the behavior of conventional concrete under chemoplastic framework is developed and validated. The model is based on new formulation of a constitutive law with new chemoplastic potential...

INTRODUCTION Performance of concrete at high temperatures is of great importance, in particular for safety evaluation of concrete structures...

... of concrete. Though concrete is a poorer conductor than steel, sustained high temperature at the surface leads to progressive heating of the inner layers of concrete. This leads to exposing reinforcing bars to higher temperature; which causes a reduction in the yield stress, ductility and tensile strength...
