“…In addition, various statistical analyses, machine learning, and optimization methods are recommended for further investigation [27][28][29][30][31][32][33][34]. Pavement failures can endanger trafc safety, and various additives and nanomaterials can be taken into account in this regard, which can be examined in a feld investigation that is in line with this study [35][36][37][38][39][40].

A horizontal curve’s geometric design is considered an important factor in highway accidents, and simple and spiral curves are regarded as the most common types of horizontal curves. Various factors affect the safety of horizontal curves, one of the most important of which is the side friction factor in the horizontal curves. Therefore, in this study, the safety of simple and spiral horizontal curves was investigated for the E-class sedan, E-class SUV, and two-axle conventional truck based on the side friction factor. In this regard, CarSim and TruckSim vehicle dynamic simulation software were utilized using 360 scenarios, including vehicle speed, vehicle type, curve radius, and road geometry. It was revealed that the maximum side friction factor for all vehicles in the simple horizontal curve was higher than the spiral horizontal curve. Also, the process of increasing the side friction factor was carried out with a gentler slope in the spiral horizontal curve. Except for the radius of 0.7 times the maximum radius of the spiral horizontal curve (R) for the truck and the radii of 0.7 R and 0.9 R for the sedan and SUV, the maximum side friction factor in simple and spiral horizontal curves was lower than the AASHTO recommended values, which shows that the spiral horizontal curve was better and safer compared to the simple horizontal curve based on the side friction factor.

“…As mentioned by Huang et al [ 81 ], creep failure of beams and structures under long-term service conditions is related to fatigue. These structures are often subjected to cyclic stress, which may reduce their ability to deform under axial stress, worsen their energy dissipation, raise their failure strength, and result in premature hardening [ 82 , 83 ]. According to Movahedi-Rad et al [ 84 ], the creep-fatigue loading pattern with a specific creep time at low stress levels does not influence the fatigue life.…”

Fibre-reinforced polymer (FRP) composites have been selected as an alternative to conventional wooden timber cross arms. The advantages of FRP composites include a high strength-to-weight ratio, lightweight, ease of production, as well as optimal mechanical performance. Since a non-conductive cross arm structure is exposed to constant loading for a very long time, creep is one of the main factors that cause structural failure. In this state, the structure experiences creep deformation, which can result in serviceability problems, stress redistribution, pre-stress loss, and the failure of structural elements. These issues can be resolved by assessing the creep trends and properties of the structure, which can forecast its serviceability and long-term mechanical performance. Hence, the principles, approaches, and characteristics of creep are used to comprehend and analyse the behaviour of wood and composite cantilever structures under long-term loads. The development of appropriate creep methods and approaches to non-conductive cross arm construction is given particular attention in this literature review, including suitable mitigation strategies such as sleeve installation, the addition of bracing systems, and the inclusion of cross arm beams in the core structure. Thus, this article delivers a state-of-the-art review of creep properties, as well as an analysis of non-conductive cross arm structures using experimental approaches. Additionally, this review highlights future developments and progress in cross arm studies.

“…Orthotropic steel decks (OSDs) have been widely used in long-span bridges because of their light weight, high strength and other advantages (Wolchuk, 1999). However, OSDs, which are mainly composed of welded components, are easily subjected to fatigue cracking under the coupled effect of welding residual stress, ambient temperature, cyclic vehicle loads and other influencing factors (Wang et al, 2019a; Zhang et al, 2022). Fatigue cracks are the permanent damage threatening the structural safety.…”

The interface bonding layer is usually adopted to connect the asphalt surfacing and steel deck plate; however, the effect of interface bonding conditions on fatigue performance of rib-deck welds still remains unclear. In this study, comprehensive finite element analysis was carried out to clarify the effect of interface bonding conditions. Parametric analysis was conducted to investigate the effect of Poisson’s ratio and elastic modulus of asphalt surfacing, and the interface bonding condition on fatigue performance of rib-deck welds, so is the coupled effect of elastic modulus and interface bonding condition. Taking into account the time-variant temperature and traffic volume, the accumulated fatigue damages in rib-deck welds were compared and analysed. Results show that the simulation of the interface bonding condition is reliable, as convinced by bending tests. The interface bonding condition and the elastic modulus of asphalt surfacing, which are both sensitive to the temperature, considerably affect the fatigue performance of rib-deck welds. The fatigue damage of rib-deck welds is underestimated if the interface bonding behaviour is not considered.
