Spalling of cover concrete is a major concern for concrete elements subjected to elevated temperature, which result in direct exposure of rebar to elevated temperature. An experimental study was conducted on thermo-mechanically treated (TMT) rebar, for studying the influence of various heating – cooling process like the one occurring during fire accidents in infrastructure. The parameters considered are temperatures ranging from 100°C, 200°C, 300°C, 400°C, 500°C, 600°C, 700°C and 800°C and two types of cooling regimes like air cooling and quench cooling. The duration of exposure was maintained as two hours at the desired temperature. The different cooling condition had no major alteration in residual strength, stiffness and ductility of reinforcement for temperature below 400°C. In the case of temperature above 400°C to 800 °C, the yield strength was decreasing for air cooled specimen when compared with the quench cooled specimens but the air cooled specimen showed better performance in the ductility of reinforcement than the quench cooled specimen.

The study emphasis the effect of elevated temperature on concrete cubes made with M20, M25, and M30 concrete grades. The other variables considered were temperature (100, 200, 400, and 600 °C), duration of exposure (1-h and 2-h) and two types of cooling methods. The mass loss is varied from 0.52 to 6.56% for various temperature and duration of exposure. The mass loss increases as the duration of exposure increased. The porosity ranges from 9.89 to 44.34% and it depends on grade of concrete and exposed temperature. The strength loss ranges from 3% at 200 °C to 57% at 600 °C for air cooled specimen. In quench cooled specimen the loss in strength varies gradually up to 200 °C but at 400 °C the loss in strength was 42%, while the loss was only 32% for air cooled specimen. The obtained residual compressive strength curve from this study was compared with strength curves proposed by various codes.

Fatigue life data is the important factor for designing, high rise buildings, bridge decks, rapid transportation systems and precast structural elements and it should to be modelled accurately. To attain a appropriate modelling data, it is vital to choose a suitable computation method. Two parameter Weibull distribution is frequently used statistical tool for modelling the flexural fatigue failure life exactly. In this article, a flexural fatigue failure life of self-compacting fibre reinforced concrete (FRC) were statistically commanded. Subsequently, a novel energy pattern factor method (NEPFM) has been proposed for the computation of Weibull shape parameter from the data of earlier researcher. The validity of the proposed NRPFM is verified with power density method and other researchers. The results revealed that the proposed NEPFM is appropriate and efficient to calculate the Weibull shape parameter for the flexural fatigue failure applications.

M. K. Haridharan and Natarajan, C., “Numerical simulation of damage in reinforced concrete slab subjected to elevated temperature”, International Journal of Earth Sciences and Engineering, vol. 8, pp. 242-248, 2015.[Abstract]


The strategy is to simulate and study the damage growth in reinforced concrete slab. Numerical model was developed using Finite Element analysis package ABAQUS. This study includes the effect of material degradation with respect to temperature and geometrical nonlinearity. The study was carried out on square slab subjected to an ISO temperature for a time period of 90mintues. Support conditions considered for the study were a) supports at all sides and b) Supports at two opposite sides. Analysis predicts the temperature distribution, thermal response, mechanical response and intensity of damage. The slab supported on all four edges had better performance than the member with supports on two opposite edges due to the formation of tension ring phenomenon which enhances the performance of load carrying capacity but large deformation was observed. The slab supported at four sides had better resistance to collapse than the supports at two opposite edges. The pinned support condition at all sides had deflection greater than the fixed condition due to the effect of thermal gradient which resulted in increased thermal bowing. In case of fixed boundary condition the material degradation was dominant than the defection but for pinned support both material degradation and deflection had equal contribution for the intensity of damage. Development of tensile member action in slabs was predicted by analyzing the intensity and nature of damage in the member. The effect of restraint, both translational and rotation influence the thermo-mechanical behavior of the member.

The reinforced concrete slabs have experienced significant levels of stressing and cracking as a result of restrained thermal deformations. However, for evaluating the thermal strains in the slab, temperature distribution of the slab is required.Temperature distribution of the reinforced concrete slab varies from point o point. The temperature of unexposed concrete slab also rises due to the adjacent slab which is exposed to fire, even though concrete is having significant resistance for the propagation of fire. In this study, temperature distribution over the surface of concret slab is obtained using finite element computer program (ABAQUS). Two different cases are considered to estimate the heat propagation through slab. In the first case, slabis subjected to fire at its center region. In the second case, slab is subjected to fire at outer region means along the walls. Modelling is carried out to predict thetemperature distribution and thermal strains of concrete slab. The other parameters considered for this study are varying thickness of slab (100 and 200 mm) and exposed temperature (100, 200, 300 and 400 °C). The duration of exposure considered for the study is 4 h.

The behavior of reinforced concrete slab exposed to fire is presented. Two stages of analysis is carried out using Finite Element package ABAQUS to find thermal response of structural members namely thermal analysis and structural analysis. In the first step, the distribution of the temperature over the depth during fire is dete rmined. In the next step, the mechanical analysis is made in which these distributions are used as the temperature loads. The responses of structure depend on the type of concrete and the interactions of structural members. The RCC slab were modeled to sho w the role of slab thickness, percentage of reinforcement, width of slab and different boundary condition when expose to fire loading. Effects for both materials in RCC slab at elevated temperatures are also evaluated.

The practical need of self-compacting concrete (SCC) is increasing due to increase in the infrastructure competence all over the world. The effective way of increasing the strength of concrete and enhance the behaviour under extreme loading (fire) is the keen interest. Glass fibers were added for five different of volume fractions (0%, 0.1%, 0.3%, 0.5% and 0.6%) to determine the optimum percentage of glass fiber without compensating the fresh properties and enhanced hardened properties of SCC concrete. The fresh state of concrete is characterized by slump flow, T-50cm slump flow, and V-funnel and L- box tests. The results obtained in fresh state are compared with the acceptance criteria of EFNARC specification. Concrete specimens were casted to evaluate the hardened properties such as compressive strength, split tensile strength, flexural strength and modulus of elasticity. Incorporation the glass fiber into SCC reduces the workability but within the standard specification. The hardened properties of SCC glass fiber reinforced concrete were enhanced, due to bridging the pre-existing micro cracks in concrete by glass fiber addition.
