Special Issue Information

Dear Colleagues,

As we are faced with the challenging times of rapid climate change and a wide-spread pandemic, there is a critical need to incorporate resilient and sustainable infrastructures for the development of smart cities worldwide. Civil infrastructures should be designed with a focus on resilient building materials while emphasizing the sustainability aspects of automated construction, evaluation and maintenance operations. Resilient and sustainable infrastructures will mitigate the impacts of extreme weather events and climate change on infrastructure performance. It is also essential to preserve existing infrastructures by developing innovative asset management systems with deep learning artificial intelligence and big data analysis. Thus, building resilient and sustainable infrastructures is one of the most critical considerations for developing smart cities.

This Special Issue aims to publish high-quality research papers as well as state-of-the-art review articles that focus on the resiliency and sustainability aspects in designing, building and managing infrastructures. The papers in this Special Issue should be focused on various advances that have taken place worldwide in resilient and sustainable infrastructure technologies for smart cities.

We would like to invite you to contribute to a Special Issue of MDPI’s Infrastructures  on infrastructures for smart cities. This Special Issue is very timely and will encompass the following, but not limited to, emerging topics:

Design of buildings and infrastructures for smart cities;

Smart sensors for the home, buildings and infrastructures;

Innovative building maintenance management systems;

Optimized infrastructure asset management systems;

Infrastructure governance;

Sustainable pavements, roads and bridges;

Resilient underground pipes and structures;

Clean air and air quality monitoring systems;

Sustainable parks and recreation facilities;

Clean water and efficient distribution systems;

Smart energy metering and power grids;

Autonomous and efficient transportation;

Smart parking meters and operations;

Video surveillance and crime prevention systems;

Efficient disaster prevention and response;

Big data and environmental lifecycle analysis;

Operation, maintenance and safety of smart cities;

Comprehensive urban planning for smart cities;

Sustainable materials for use in infrastructures;

Laboratory and field tests of sustainable infrastructure materials;

Smart and automated construction equipment;

Automated infrastructure evaluation using emerging technologies such as drones.

We look forward to receiving your contributions; the deadline for submissions is 30 June 2021.

Sincerely,

Dr. Savis Gohari

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Infrastructures is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

The application of Ultra-High-Performance Concrete (UHPC) materials in rehabilitating bridges and constructing primary bridge components is increasing rapidly across the world because of their superior strength and durability characteristics when compared to regular concretes. However, there have been few new bridges constructed using UHPC materials with regular formworks, ready-mix trucks, and construction equipment. This paper presents a comprehensive report encompassing the design, construction, and performance monitoring of a new bridge constructed in Iowa using a unique UHPC technology that includes steel fibers of two different lengths embedded in the concrete. By using optimized lengths of steel fibers, both the tensile strength and the toughness were increased. The UHPC material was produced with local cement and aggregates in the US using typical ready-mix concrete equipment. This paper discusses the experience gained from the design and construction process including mix design, batching, delivery of steel fibers to the ready-mix concrete batch unit, and post-tensioning of precast slabs at the jobsite. For four years after construction, the joints of the bridge decks were monitored using strain sensors mounted on both sides of the deck joints. The strain values were quite similar between the two sides of each joint, indicating a good load transfer between precast bridge girders. A bridge was successfully constructed using a unique UHPC technology incorporating two different lengths of steel fibers and utilizing local cement and aggregates and a ready-mix truck, and has been performing satisfactorily with a good load transfer across post-tensioned precast girder joints.

The current developments in onboard power source technology, in particular, traction batteries, open up new potential in trolleybus transport and also make it possible to introduce electric buses. Thus far, trolleybus transport has required the presence of overhead lines (OHL). Introducing trolleybuses with onboard batteries makes it possible to grow the zero-emissions transport network in places with limited power supply capabilities and low population density, or in places where building OHL would not be possible. This improves the efficiency of trolleybus transport and makes environmentally friendly public transport more accessible to the local citizens. Despite their obvious advantages, traction batteries can also be problematic, as the drivers may overuse them (e.g., in the event of pantograph failure), and the public transport authorities and transport companies may plan connections in an ineffective way without preparing the necessary infrastructure (the absence of slipways or automatic connection capabilities), which in turn leads to inefficient use of the OHL. The article outlines the operation of the trolleybus transport network in Gdynia. The use of traction batteries in regular connections is analysed, and the potential for electrification of the bus line, some sections of which follow the traction infrastructure, is examined.
