Abstract.Nowadays, vehicle-induced vibration is a subject matter interest in the bridge monitoring field. As compared to other types of excitation such as earthquake and accidental impact, the vehicle-induced vibration is often being less considered during the design process of the bridge. The newly implementedcode also does not emphasize on the vibration check for vehicular bridge and requires the engineers to refer to other "unnamed literature" if they would want to consider vibration check during the design process. However, in recent years there were few reported cases of road users experiencing the excessive vibration when they travelled on certain bridges, therefore raising concern among the bridge designer community the need for vibration check. This paper reviews several conducted researches on vehicle-induced vibration on the real bridge, the methodologies adopted and the outcome from each research. While there are extensive research been conducted on the real bridge, this review is limited to the conducted research into the different categories of bridges. Vehicle-induced vibration usually used for modal testing of the vehicular bridges and is chosen due to the flexibility offered by this method as type of excitation. Most of the researchers focused on the vibration by the vehicle of common bridge while less researches for the integral type. In the context of the integral bridge construction in Malaysia, bored pile is widely being used rather than H-type piles for integral bridges. Hence, there is a need for further exploration on the combination of integral type bridges with the bored pile foundation to assess their dynamic characteristics.

“…In order to achieve good peak response qualities, the paper aims to design a controller (12) such that the closed-loop system (13) is asymptotically stable for all admissible parameter uncertainties in spite of the saturation constraint, and the closed-loop system (13) guarantees, under zero initial condition, kzk " < kwk 2 , i.e., energy-to-peak performance, where > 0 is a prescribed constant, for all non-zero w 5 L 2 [0, 4).…”

“…In civil engineering, the control of building structures subject to earthquakes or strong winds has received considerable attention over the past three decades and much e ort has been devoted to the development of control devices and algorithms [6,7,8]. With recent focus on wireless monitoring and control of structural systems [9,10,11,12] based on networked control technique [13], studying sampleddata control problem for structures is becoming signi cant. Classical solutions to this type of feedback control problem as well as their applications in civil engineering can be found in the literature [14,15,16], where optimal discrete-time and sampled-data control algorithms taking into account external excitations were developed for structural engineering applications.…”

Abstract"This paper presents a robust sampled-data controller design approach for vibration attenuation of civil structures considering parameter uncertainties and actuator saturation. The parameter uncertainties belong to polytopic form and are assumed to be the variations of the structural stiffness and damping. Regarding the uncertain sampling problem encountered in real world applications, the sampling period designed for the controller is allowed to be variable within a given bound. In order to obtain reduced peak response quantities, the energy-to-peak performance used to describe the peak values of the control output under all possible energy-bounded disturbances is optimised. The robust sampled-data state feedback controller is obtained in terms of the solvability of certain linear matrix inequalities (LMIs). The applicability of the proposed approach is demonstrated by a numerical example on vibration control of a building structure subject to seismic excitation. It is validated by the simulation results confirming that the designed controllers can effectively attenuate the structural vibration and keep the system stability while there are parameter uncertainties and actuator saturation constraints.

“…[5]. A different approach is described in [6], where a WSN is organized in a star topology in which 20 nodes sampling at 128 Hz continuously transmit data in real-time to the sink node for operational modal analysis. WSNs are exploited also for structural control: in [7], the sensing nodes periodically transmit measurements to the controlling nodes, which process the data and calculate the proper control forces to be applied at the dampers.…”

Abstract-Structural health monitoring aims to provide an accurate diagnosis of the condition of civil infrastructures during their life-span by analyzing data collected by sensors. To this purpose, detection and localization of damages are fundamental tasks. This paper introduces a wireless sensor network for structural damage detection and localization in which the sensor nodes, in order to estimate the energies of specific frequency bands, process the acceleration data locally in real-time using the Goertzel algorithm. The nodes then share their results inside the network and exploit them to compute transmissibility functions, which can be exploited as damage indicators and for correctly localizing damages within the monitored structure. The use of the embedded Goertzel algorithm prevents the nodes from transmitting large volumes of acceleration data to the sink node for off-line analysis, reducing the latency and increasing the life time of the cyber-physical system by 80 % and 52 %, respectively. The tests performed on a truss structure confirm the capability of the distributed approach in correctly detecting and localizing structural damages.
