Sensitivity Analysis for Pedestrian-Induced Vibration in Footbridges
This paper aims to provide a novel insight into the influence of uncertainties in system- and pedestrian-induced load parameters on the vibration response of footbridges. The study begins with a sensitivity analysis for the vertical vibration response of

Shear Lag Effects on Pedestrian-Induced Vibration and TMD-Based Vibration Control of Footbridges
The shear lag effect (SLE) is one of the vital mechanical characteristics of structures with thin-walled box sections. While most existing studies of the SLE focus on the static response of footbridges, pedestrian-induced vibration deserves more ...

Serviceability analysis for human-induced vertical vibration on pedestrian structures
Civil engineering structures such as grandstands, slabs, footbridges and staircases have reported unacceptable vertical vibration when they are affected by human activities. Even when most of these structures are designed according to current guidelines

The paper focuses on the optimal design of the grounded tuned mass damper inerter (TMDI) in footbridges and on some practical implementation issues. An optimal design procedure is implemented for the perfectly grounded ideal TMDI (infinite stiffness of ...

Evaluation of Pedestrian Facilities in Al-Najaf City [PDF]
Less attention to pedestrian facilities significantly affects traffic flow, such as side friction and delay. It was noted that a high interaction, in Al-Najaf city, with the vehicular stream by pedestrians resulted in a reduction in the performance of ...

Modelling of lateral forces generated by pedestrians walking across footbridges
The mechanism which results in the synchronization of people walking across footbridges with the bridges fundamental horizontal frequency is studied. The lateral vibration of a bridge subjected to walking pedestrians is modelled by considering the bridge

Comparative analysis of dynamic load models generated by runners on footbridges [PDF]
Footbridges, like all building structures, must be designed in a way that ensures their safe and comfortable use. Steel footbridges characterised by low vibration damping often turn out to be a structure susceptible to the dynamic influence of users ...

Optimal Design of Steel Structures Using Innovative Black Widow Algorithm Hybridized with Greedy Sensitivity-Based Particle Swarm Optimization Technique [PDF]
This paper presents a Greedy Sensitivity-based analysis implemented on the Particle Swarm Optimization search engine (GSPSO). The effectiveness of the method focuses mainly on providing an intelligent population to enter meta-heuristic algorithms.

Design of Steel Footbridges for Unpredictive Loadings by STAAD Pro: LRFD vs. ASD for Cost Saving
Steel footbridges are common means of connecting two zones separated by any kind of physical obstruction to the pedestrian crossing. In the last century, they were mostly designed using manual calculations.
