In this study, a damage detection method for reinforced concrete (RC) beams using the modal strain energy (MSE) combined with confusion matrix model is proposed. This used identifying crack zone position and length of RC under various loadings. The beam modelled by ANSYS APDL software. To prove finite element model’s validity, static properties are compared experimental data theoretical calcula...

The usual earthquake resistant design philosophy of ductile frame buildings allows the beams to form plastic hinges adjacent to beam-column connections. In order to carry out this design philosophy, the ultimate bond or shear strength of the beam should be greater than the flexural yielding force and should not degrade before reaching its required ductility. The behavior of RC members dominated...

The main objective of this study is to propose the Strut-and-Tie method (STM) to predict the shear capacity of simply supported RC deep beams shear-strengthened with carbon fiber reinforced polymers (CFRP). It is assumed that, the total carried shear force by shear-strengthened RC deep beam provided by three independent resistance, namely diagonal concrete strut due to Strut-and-tie mechanism, ...

This study proposes a novel artificial intelligence (AI) model to estimate the shear strength of reinforcedconcrete (RC) deep beams. The proposed evolutionary multivariate adaptive regression splines (EMARS) model is a hybrid of multivariate adaptive regression splines (MARS) and artificial bee colony (ABC). In EMARS, MARS addresses learning and curve fitting and ABC implements optimization to ...

We propose a new approach of direct detection SDMWDMFSO beams using the newly developed resonant cavity (RC) 4×4 photodetector (PD) array device, which integrates functions in such as an waveguide grating (AWG), multi-parallel photoreceivers, and mitigating optical alignment tolerance conventional WDMFSO system into one chip. The RC-PD device worked for not only wavelength separation WDM beams,...

A methodology for reliability analysis of reinforced concrete (RC) beams strengthened with ultra high-performance fibre (UHPFRC) tensile layers is presented. The proposed includes stochastic stress-block a section, assuming perfect bond between the RC beam and UHPFRC layer. Annual before after strengthening operation conducted. Deterioration induced by chloride corrosion incorporated into via m...

Fiber Reinforced Cementitious Matrix (FRCM) materials are widely used for strengthening reinforced concrete (RC) structures. Experimental studies show that the collapse of RC elements with FRCM composites occurs due to loss bond reinforcing material. For this reason issue shear stress transfer between reinforcement and substrate has been extensively studied in last years. The single-lap test is...

This study investigates the behavior of three concrete beams reinforced with steel and GFRP bars under fire exposure. The tests were conducted including one control steel-reinforced (RC) beam two GFRP-RC beams. exposed to according standard curve ISO 834 for 3 h. investigation parameters included reinforcement types (i.e., bars) diameter bars. Based on experimental results, during exposure, def...

Upgraded design standards coupled with the damage caused by natural disasters have led to development of smart materials potential modernize current construction practices. This investigation proposes a nonlinear finite element (FE) model for evaluating performance beam–column joints (RC-BCJ) reinforced shape memory alloys (SMA) and steel rebars. The was validated based on accredited experiment...

This paper deals with the effect of steel fiber amounts and interaction between amount stirrup ratio on shear behavior capacity reinforced concrete (RC) deep beams fibers. The experimental program was carried out twelve different (0, 30, 40, 65 kg/m3) ratios (0.1, 0.15, 0.25%). test results have shown that use fibers increased resistance (up to 55%), reduced crack width 11 times) deflection 57%...
