  Iris Publishers- Peer Review Journal of Civil and Structural Engineering Fundamentals for Cracking Verification of Reinforced Concrete Structures Abstract A mathematical model, named as general method, has been set up to study the cracking behaviour of a concrete tie reinforced by ordinary bars, subjected to a monotonic load. The analysis is performed considering both the crack formation stage and the stabilized cracking stage. In particular, secondary cracks occur in the stabilized cracking stage, modifying the distribution of bond stress along the transmission length. As in the stabilized cracking stage the solution of the general method requires to carry out an iterative numerical procedure, for design purposes the maximum crack width can be determined through a simplified method that allows the main aspects of the structural behaviour to be taken into account. Introduction Cracking in concrete structures has to be considered normal and, in general, it does not indicate a...

   Iris Publishers - Scholarly Open Access Journal of Civil and Structural Engineering Green Construction Materials and the Circular Economy Abstract This opinion article concerns the minimization of the environmental impacts of the cement and concrete industries. The article identifies the processing of carbon dioxide that results from cement production and the incorporation of construction and demolition waste on concrete as key objectives for environmental sustainability, discusses concepts related to both objectives, and presents the mission of c5Lab - Sustainable Construction Materials Association, a consortium that intends to contribute to the greening of the cement and concrete industries. Keywords: Sustainability; cement; concrete; carbon dioxide; construction and demolition waste; circular economy Introduction Reinforced Concrete stands as the main Structural material for large buildings and many other Civil Engineering works, with many emblematic structures, from the...

   Iris Publishers - Peer Review Journal of Civil and Structural Engineering Proportional Examination of Pf Mechanical Composition of Concrete Produced with Washed and Unwashed Gravel Abstract Concrete is a very important material in the Nigerian construction industry as over 90% of her storey buildings are made from reinforced concrete. Local gravel is being increasingly used as coarse aggregate in place of the more expensive crushed granite in the production of concrete in parts of the country where it is found. Hence, this study aims at comparing the mechanical properties of concrete produced with washed and unwashed gravel to identify the most suitable aggregate for concrete. The use of two types of course aggregates for different works is examined in this study. Typical strength concrete is being made from various aggregates and their impact on various characteristics to the subsequent concrete. Compressive strength is the most vital property of concrete. In this paper, t...

 Iris Publishers - Open Access Journal of Civil and Structural Engineering Modern and Future Issues facing Civil Engineering and Construction Abstract The world of construction and civil engineering faces many broad issues in today’s climate. These issues affect areas such as road, bridge, rail, ship, general building construction, as well as oil and gas projects, tunnels, dams and wind farms. The civil engineering profession involves a lot of sub- disciplines and deals with the infrastructure and maintenance of built environments. As civil engineers there is a social responsibility to maintain and adapt structures to make life manageable. In this brief article we aim to highlight some of the most pressing issues that are occurring, and we offer some solutions and thoughts. Keywords: Civil engineering; Challenges; Infrastructure; Community; Sustainable; Safety; Management; Pandemic; Covid-19 Introduction There are a lot of pressures on civil engineers these days, and in order to su...
