“…Neves et al (2012) presented a direct method to analyze the vertical interaction between vehicle and structure. This subject is also treated by recent works (Koç and Esen, 2017;Daniel and Korti s, 2017;Greco and Lonetti, 2018;Godbole et al, 2019).…”

PurposeRealistic composite vehicles with 2, 3, 5 and 9 axles, consisting of a truck with one or two trailers, are addressed in this paper by computational models for vehicle–bridge interaction analysis.Design/methodology/approachThe vehicle–bridge interaction (VBI) models are formed by sets of 2-D rigid blocks interconnected by mass, damping and stiffness elements to simulate their suspension system. The passage of the vehicles is performed at different speeds. Several rolling surface profiles are admitted, considering the maintenance grade of the pavement. The spectral density functions are generated from an experimental database to form the longitudinal surface irregularity profiles. A computational code written in Phyton based on the finite element method was developed considering the Euler–Bernoulli beam model.FindingsSeveral models of composite heavy vehicles are presented as manufactured and currently travel on major roads. Dynamic amplification factors are presented for each type of composite vehicle.Research limitations/implicationsThe VBI models for compound heavy vehicles are 2-D.Social implicationsThis work contributes to improving the safety and lifetime of the bridges, as well as the stability and comfort of the vehicles when passing over a bridge.Originality/valueThe structural response of the bridge is affected by the type and size of the compound vehicles, their speed and the conservative grade of the pavement. Moreover, one axle produces vibrations that can be superposed by the vibrations of the other axles. This effect can generate not usual dynamic responses.

“…However, since on-site time is minimal in a prefab construction, temporary loads act on fully or partially finished modules or panels during their transport, lifting and handling. These loads that act on a structure during its transportation can be estimated according to the findings of some recent studies [25][26][27]. Although the stiffness of temporary bracing and the permanent structural frame should be checked against these loads, proper guidance on transportation-induced loading has not yet adequately appeared in the design standards of buildings.…”

Modern Methods of Construction with Offsite Manufacturing is an advancement from prefabricated technologies that existed for decades in the construction industry, and is a platform to integrate various disciplines into providing a more holistic solution. Due to the rapid speed of construction, reduced requirement of labour and minimised work on site, offsite manufacturing and prefabricated building systems are becoming more popular, and perhaps a necessity for the future of the global construction industry. The approach to the design and construction of prefab building systems demands a thorough understanding of their unique characteristics.

“…A pitch-plane vehicle model with hinges connecting the individual articulated parts describes the bouncing and pitching motions of a multi-axle articulated vehicle. Since the dynamic responses such as accelerations and forces associated with the above motions can be captured based on the known equation of motion of the vehicle model and the input road profile conditions [ 1 , 2 , 3 ], calibration of the parameters of a multi-axle articulated vehicle model is a crucial requirement to obtain realistic dynamic responses of the articulated vehicle. Recently, much attention has been paid to simulating the dynamic responses of a moving articulated vehicle involving multiple disciplines.…”

The realistic simulation of the dynamic responses of a moving articulated vehicle has attracted considerable attention in various disciplines, with the identification of the vehicle model being the prerequisite. To this end, a double-sensor hump calibration method (DHCM) was developed to identify both unladen and laden vehicle models, consisting of a sensor layout optimization step and a system identification step. The first step was to optimize the number and position of sensors via parameter sensitivity analysis; the second was to inversely identify the vehicle system based on sensor responses. For comparison, the DHCM and the existing single-sensor hump calibration method (SHCM) were used to calibrate a small-sized vehicle model and a multi-axle articulated vehicle model. Vertical accelerations of the vehicle models were then simulated and characterized by power spectral densities (PSDs). Validation against experimental measurements indicated that the PSDs of the models identified with the DHCM matched the measured PSDs better than those of the SHCM, i.e., the DHCM-identified model accurately simulated the dynamic response of an articulated vehicle with relative errors below 16% in the low-frequency range. Therefore, the DHCM could identify models of small-sized vehicles and multi-axle articulated vehicles, while the SHCM was only suitable for the former.
