چکیده

This article describes an experimental investigation on a reinforced concrete bridge deck to compare half-cell potential measurements carried out from the under-side to those obtained from the upper-side of the deck. It was noted that the results are similar but are not identical. This particular situation is caused by the physical conditions of the upper-side and lower-side of the decks which, sometimes, can be similar. Résumé Cet article concerne une investigation expérimentale sur une dalle de tablier de pont pour comparer les mesures de potentiel de corrosion obtenues par l’intrados et par l’extrados. Il a été constaté que les résultats sont similaires mais ne sont pas identiques. Cette situation est attribuée aux conditions physiques de l’intrados et de l’extrados qui, parfois, peuvent être similaires.

Shear Capacity of Reinforced Concrete Flat Slabs Made with High-strength Concrete: A Numerical Study of the Effect of Size, Location, and Shape of the Opening (TECHNICAL NOTE)

Nowadays, concrete with strength higher than 50 MPa is utilized due to the ever increasing need for higher strength and prolonged healing properties. Despite the widespread use of high-strength concrete, only a few research projects have been conducted on the punching shear strength of high-strength concrete slabs. Reinforced concrete flat slabs are widely employed in structural systems. The lo...

بررسی عددی دال‌های بتنی مسلح شده به ورق‌های حفره‌دار فولادی تحت بارگذاری انفجار

This paper aims to study the numerical behavior of concrete slabs reinforced with perforated steel plates (PSPs) through nonlinear finite element (FE) analysis performed by ABAQUS. In this regard, conventional steel rebars (CSRs) are replaced with (PSPs) in the concrete slabs. Due to the particular geometry that the configuration of the hole provides, these PSPs are more integrated with surroun...

The Effect of Caspian Sea Water on Corrosion Resistance and Compressive Strength of Reinforced Concrete Containing Different SiO2 Pozzolan

Many parameters are influenced by the diffusion of chloride on concrete in marine environments and these can affect concrete quality. In this study, the effect of water to cement ratio of 0.35, 0.40 and 0.45 on corrosion resistance and compressive strength of reinforced concrete was evaluated. Moreover, different percentages of micro silica (SiO2) including 5, 7.5 and 10% were utilized, in orde...

Estimation of Punching Shear Capacity of Concrete Slabs Using Data Mining Techniques

Punching shear capacity is a key factor for governing the collapsed form of slabs. This fragile failure that occurs at the slab-column connection is called punching shear failure and has been of concern for the engineers. The most common practice in evaluating the punching strength of the concrete slabs is to use the empirical expressions available in different building design codes. The estima...
