This study develops a new approach for forecasting shear Strength of concrete beam without stirrups based on the artificial neural networks (ANN). Proposed ANN considers geometric and mechanical properties of cross section and FRP bars, and shear span-depth ratio. The ANN model is constructed from a set of experimental database available in the past literature. Efficiency of the ANN model was c...

Transportation is an important part of modern community life as well as one of the largest sources of greenhouse gas emissions in urban communities, the population growth of which can increase transportation capacity. Monorail systems are relatively new rail transportation systems which are currently being designed and constructed in different countries. We have applied the Intergovernmental Pa...

in fact the most suitable method for finding the load bearing capacity of a member under the axial load or axial load and bending is make use of the interaction diagrams. to analysis and design the hollow circular, square and rectangular high strength concrete (hsc) column shapes, a linear strain variation was assumed in the cross-section height of the members and then the static equilibrium eq...

In this study, we aim to investigate the interaction between alkali-silica reaction (ASR) expansion and multi-directional reinforced steel bars, clarify weakening mechanism of bond performance under influence interaction. First, a series pullout specimens considering bar diameter stirrup number were prepared then different degrees accelerated ASR test quantify restraint effect bars. After test,...

In order to quantitatively evaluate the shear-bearing capacity of shear connectors of square concrete filled steel tube (CFST), push-out tests on 14 square CFSTs with shear connectors have been carried out. Among the 14 CFSTs, there are 13 specimens with steel plate connectors and one specimen with steel bar connectors. The following factors are investigated to figure out their influences on th...

Abstract Simplified assumptions have traditionally been made on the rebar–to–concrete interaction in structural concrete to calculate stress state rebars. Such typically consider a uniform reinforcement at given cross section, neglecting compatibility of deformations due bending bar. simplifications are fully justified relatively ductile behaviour reinforcement. When ductility is however not su...

Bar diameter is one of the basic factors affecting bond behavior, which still interest due to opposing opinions regarding its effect on behavior in pull-out test. This paper presents an experimental and numerical analysis ribbed reinforcing bar concrete. The aim was experimentally evaluate test perform simulations conducted experiments ABAQUS verify their convergence obtained results. used conc...

This paper presents a study about the bond of high strength concrete with high strength steel. Fourteen pull out tests were carried out to determine the bond. The concrete strength was about 70 MPa and the steel was a 500 MPa grade. Bar diameters used were 12, 16, 20, 25, 28, 32 and 36 mm. In order to investigate the effect of cover, each test was done twice, once in a 240 mm diameter concrete ...
