Road infrastructure is a vital aspect in transportation systems and can be severely affected by disasters. Postdisaster impact assessment is vital for the repair and reconstruction of such infrastructure, which is constrained by budget and time. This review provides a detailed analysis of prior literature on postdisaster impact assessments of road infrastructure. The related methods used in the literature were analyzed based on their classifications, such as social, environmental, and economic impacts of road failure. It was determined that although a wide range of methods have been used to assess economic impacts, there is still a lack of research measuring environmental and indirect social impacts. Prior literature has also highlighted that the use of bottom-up models to assess socioeconomic impacts is more relevant in the aftermath of a disaster. This paper presents a systematic review of the literature and guidelines for selecting the most appropriate method to assess impacts. This review aims to provide a frame of reference for researchers and government authorities involved in postdisaster impact assessment and decision making related to road infrastructure.

Purpose

Current methods for floodway design are predominately based on hydrological and hydraulic design principles. The purpose of this paper is to investigate a finite element methods approach for the inclusion of a simplified structural design method into floodway design procedures.

Design/methodology/approach

This research uses a three-dimensional finite element method to investigate numerically the different parameters, geometric configurations and loading combinations which cause floodway vulnerability during extreme flood events. The worst-case loading scenario is then used as the basis for design from which several structural design charts are deduced. These charts enable design bending moments and shear forces to be extracted and the cross-sectional area of steel and concrete to be designed in accordance with the relevant design codes for strength, serviceability and durability.

Findings

It was discovered that the analysed floodway structure is most vulnerable when impacted by a 4-tonne boulder, a 900 mm cut-off wall depth and with no downstream rock protection. Design charts were created, forming a simplified structural design process to strengthen the current hydraulic design approach provided in current floodway design guidelines. This developed procedure is demonstrated through application with an example floodway structural design.

Originality/value

The deduced structural design process will ensure floodway structures have adequate structural resilience, aiding in reduced maintenance and periods of unserviceability in the wake of extreme flood events.

Clause 19 of the Victoria Planning Provisions (VPP) outlines the importance of planning for the timely delivery of social and physical infrastructure, and states that planning authorities should consider the use of infrastructure contributions to assist in achieving this. Infrastructure contributions have been collected in Victoria for some time, but it was not until 1995 that the Development Contributions Plan (DCP) system became legislated in the Planning and Environment Act. This legislation was prompted by a landmark legal case in a greenfield setting known as the {\textquoteright}Eddie Barron decision{\textquoteright} which resulted in the principles of need, nexus, equity and accountability forming the basis of the way in which development contributions are collected in Victoria. The introduction of the Infrastructure Contributions Plan (ICP) system in October 2016 was the first significant change to the way in which development contributions are collected since this legislation was introduced. The ICP currently applies to metropolitan greenfield settings, the application of the system in regional growth areas and strategic development areas is yet to be resolved.

Sustainability necessitates the protection of infrastructure from any kind of deterioration over the life cycle of the asset. Deterioration in the capacity of reinforced concrete (RC) infrastructure (e.g., bridges, buildings, etc.) may result from localised damage sustained during extreme loading scenarios, such as earthquakes, hurricanes or tsunamis. In addition, factors such as the corrosion of rebars or ageing may also deteriorate or degrade the capacity of an RC column, thereby necessitating immediate strengthening to either extend or ensure its design life is not limited. The aim of this paper is to provide a state-of-the-art review of various strengthening and repair methods for RC columns proposed by different researchers in the last two decades. The scope of this review paper is limited to jacketing techniques for strengthening and/or repairing both normal- and high-strength RC columns. The paper also identifies potential research gaps and outlines the future direction of research into the strengthening and repair of RC columns.
