Aims and Scope

The Open Civil Engineering Journal is an Open Access online journal which publishes research, reviews/mini-reviews, letter articles and guest edited single topic issues in all areas of civil engineering.


The Open Civil Engineering Journal, a peer-reviewed journal, is an important and reliable source of current information on developments in civil engineering. The topics covered in the journal include (but not limited to) concrete structures, construction materials, structural mechanics, soil mechanics, foundation engineering, offshore geotechnics, water resources, hydraulics, horology, coastal engineering, river engineering, ocean modeling, fluid-solid-structure interactions, offshore engineering, marine structures, constructional management and other civil engineering relevant areas.

Evaluating Fresh and Hardened Properties of High-Strength Concrete Including Closed Steel Fibres

Sarah Al-Qutaifi, Ali Bagheri

Background:

The tensile strength of the plain concrete is weak. Thus, fibres are embedded in concrete to improve its ductility. However, pulling out steel fibres from concrete structures is one of the most encountered issues in the fiber-reinforced concrete, which hinders using their maximum capacities.

Objectives:

Thus, closed steel fibres (square shape) were incorporated into concrete mixes to evaluate their impacts against the pulling-out effects and assess the feasibility of applying Closed Steel Fibres (CSFs) on the fresh and hardened concrete properties. Hooked end and straight steel fibres were also investigated for comparison.

Methods:

The utilized steel fibres were incorporated with lengths of 20, 30, and 40 mm, and volume fractions of 0.25%, 0.50%, and 0.75%. Silica Fume (SF) was involved in the fibre-reinforced concrete mixtures at 7% of the cement weight.

Results:

Paper outcomes stated that the inclusion of steel fibres involved different impacts on the concrete compressive strength depending on the applied fibre geometries and content.

Conclusion:

CSFs exhibited better performance against the pulling-out effect from the surrounding concrete structure than those of hooked end and straight steel fibres. However, the addition of CSFs has increased the concrete permeability due to their poor space-filling capacity.

Integrated Empirical-mechanical Seismic Vulnerability Analysis Method for Masonry Buildings in Timișoara: Validation based on the 2009 Italian Earthquake

Nicola Chieffo, Iasmina Onescu, Antonio Formisano, Marius Mosoarca, Marius Palade

Background:

Timisoara is one of the most important Romanina cities, located in the Banat area and characterised by shallow earthquakes with high ground motion vertical component. The seismicity of the area, in accordance with the P-100 Romanian Code, is affected by medium-high hazard level with an expected maximum PGA of 0.20 g.

From a historical-artistic point of view, the city of Timisoara is full of monumental buildings of inestimable values and it was declared as the European Capital of Culture for 2021.

Aims:

The present work aims to investigate the seismic vulnerability of masonry buildings located in the districts of Fabric and Iosefin, which were grouped in typology classes based on the EMS-98 scale according to their geometrical and structural characteristics.

Methods:

The performed vulnerability analysis is based on a combined empirical-mechanical procedure to estimate the propensity at the damage of the buildings surveyed.

Results:

A specific formulation was proposed for typological vulnerability curves of building classes of the examined area, which were calibrated on the basis of the damages detected after occurred earthquakes.

Conclusion:

The proposed formulation was validated from the application to an urban sector of the municipality of San Pio delle Camere (Italy), which was damaged after the 2009 Abruzzo earthquake.
