obtaining temperature distribution data of slabs under rolling is essential as the mechanical and metallurgical properties of the metal under this process vary with temperature. using the control volume method, a mathematical model is employed in this study to predict slab temperature in the hot roll process at mobarakeh steel company. the effects of different parameters including the heat resu...

RC flat slabs supported by an array of columns subjected to the action impulsive pressure were investigated. The designed for static loads according current standards. dynamic responses 4 × 4- and 8 8-column-supported similar, as damage failure. A simplified model consisting a tributary area central column yielded similar results, demonstrating accuracy its reliability. These analyses exhibited...

This study presents the results of an experimental program to investigate the effectiveness of an innovative combined FRP technique using combination of externally bonded (EB) FRP fabrics and near surface mounted (NSM) FRP rods for flexural strengthening of existing reinforced concrete (RC) two-wayslabs with low clear cover thickness. Three full-scale RC slabs (1500×1500×120 mm) were tested und...

Abstract: The seepage control system of a high Concrete Face Rock-Fill Dam (CFRD) may have anti-seepage deficiencies during both construction and operation. In order to solve these, the three-dimensional Finite Element Method (FEM) model was built based on dam body filling, anti-seepage system, defect location and bedrock distribution. The seepage field simulation and computation were carried o...

• A finite element model of composite cellular beams with PCHCS was developed. parametric study carried out by geometrical non-linear analyses. Symmetric and asymmetric section were considered. The predominant failure mode the web post buckling. strength not limited only beam. This paper aims to predict ultimate behavior steel–concrete using precast hollow core slabs. is developed analysis. out...

This paper proposes a macro-model for simulating the hysteretic behavior of composite-steel beams as part fully restrained beam-to-column connections in moment-resisting frames (MRFs). Comparisons with experimental data suggest that proposed model captures asymmetric response including cyclic deterioration strength and stiffness. Moreover, primary slab-column force transfer mechanisms predicts ...

Considering the development of urban transportation systems and importance highway bridges in a city’s resilience against earthquakes, it is critical to pay special attention seismic risk evaluation bridges. The most significant issue consider assessment possible direct indirect damages imposed on before an earthquake. After this, best practices for bridge rehabilitation can be adopted minimize...

Shear reinforcement is one of the common measures used to strengthen slab–column connections. It can make joint’s load capacity increase. However, when connection subjected an unbalanced bending moment, reduction effect shear on moment worth investigating. Nonlinear finite element analysis was performed reinforced concrete slabs with for various moment-to-shear (M/V) ratios. The effects number ...
