A closed-form solution is presented for the dynamic response of a two-axle asymmetric vehicle moving over bridges, along with potential applications highlighted. First, by modeling the vehicle as two concentrated loads moving over the bridge, closed-

A simple, theoretical framework is presented for identifying the damping ratios of simply supported beams using a two-axle moving test vehicle, equipped with uniformly spaced accelerometers and laser sensors. The latter are used to measure the relati

This paper presents a general framework for the dynamic analysis of high-speed maglev trains running on elastic transitional viaducts, a complicated problem that lacks an efficient analysis tool. Unlike the straight and circular tracks, both the curv

In this paper, the modal coupling mechanism is studied of a single-span footbridge consisting of a suspended beam (i.e., bridge deck), two suspension cables (via hangers) and two wind guys (via wind ties). To start, the governing equations for the sl

Exact solutions for hysteretically damped free vibrations of tapered longitudinal beams are obtained instead of undamped free vibrations. Also forced vibrations of tapered longitudinal beams with hysteretical damping are studied by a closed-form exac

This paper presents an experimental investigation of the mechanical properties of sixty A4-70 and A4-80 stainless steel bolts under steady-state temperatures ranging from 20 to 900 °C. The material responses at elevated temperatures of the parent ma

This paper studies theoretically the retrieval of torsional-flexural frequencies of mono-symmetric thin-walled box girder bridges from vehicles’ residual contact response for the first time. To start, the three-dimensional vehicle–bridgeequations

A moving impulse load generated by a heavy cogwheel can be used as a testing excitation for bridges. This novel type of dynamic load acts along the entire driving path, its intensity is adjustable, and it can be very efficient in the case of resonanc

In recent years, a coupled composite shear wall system consisting of steel reinforced concrete (RC) composite wall piers and steel coupling beams has been widely used for lateral force resistance i...
