چکیده
The nonlinear torsional behaviour of small-scale reinforced concrete (RC) beams with continuous staggered spiral as transverse reinforcement stirrups is experimentally investigated. Twelve miniatures RC were tested under torsion load considering the closed shape and compared ones. All scaled down to be one-eighth prototype beam size. main parameters considered in this research are stirrup spacing its configurations. Small scale taken into account existing study because their construction simplicity financial feasibility. Mortar without coarse aggregate was applied instead reduce size effect applying small models. Ongoing trials have been carried out obtain an efficacious approach boost failure mechanisms brittle structural elements should avoided. This emphasized boosted capacity, dissipated energy, helical crack propagation. During testing, primary cracking moment, ultimate peak twist angle, mechanism inspected. use showed great enhancement samples. It observed that using rather than could result a substantial increase capacity energy 87.7% 89.8%, respectively. As result, predicted capacities estimated detail, taking factor implemented by authors. Values obtained based on international specifications guidelines used compare experimental results.

The prepared models are functions of compressive strength , percentage of flexural reinforcement and depth of beam. The proposed models have been va...
متن کاملReliability Analysis of Corroded Reinforced Concrete Beams Using Enhanced HL-RF Method
Steel corrosion of bars in concrete structures is a complex process which leads to the reduction of the cross-section bars and decreasing the resistance of the concrete and steel materials. In this study, reliability analysis of a reinforced concrete beam with corrosion defects under the distributed load was investigated using the enhanced Hasofer-Lind and Rackwitz-Fiessler (EHL-RF) method base...
متن کاملReinforced Concrete Columns in Torsion (RESEARCH NOTE).
ACT does not suggest any regulations for columns under torsion. However, by all means, the number of such columns used in steel and concrete structures is abundant. In this paper, using the results of laboratory tests on 35 square and rectangular columns with intermediate slender ratios, relations for determination of torsional strengths of reinforced concrete under axial compression have been ...
