Structural Control & Health Monitoring, 2021 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 ...

Informes de la Construccion, 1964 La pasarela recientemente construida en Des Moines (EE. UU.), presenta la notable particularidad de tener sus accesos en curva y apoyarse sobre pilares de forma cilíndrica. Como el terreno no tenía suficiente resistencia de sustentación se tuvo que reforzar hincando pilotes para hormigonar, sobre ellos, la solera en la que descansa el montante ...

Evaluation of Pedestrian Facilities in Al-Najaf City [PDF]
E3S Web of Conferences, 2023 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 ...

Comparative analysis of dynamic load models generated by runners on footbridges [PDF]
Archives of Civil Engineering, 2023 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 ...

Structure and Infrastructure Engineering, 2021 Despite extensive research in the field of human-induced vibration in the last twenty years, there is still lack of reliable load and response models to assess vibration serviceability of footbridges under human-induced excitation, especially with ...

Design of an emergency footbridge
WIT Transactions on The Built Environment, 2014 This paper will describe the design of a temporary emergency floating footbridge, to be made when the infrastructure is destroyed by a flood, hurricane, tsunami or any other disaster. The bridge is made of identical floating modules. The modules are composed of prefabricated elements: two trusses, a pontoon and the footpath.

Deployment of a Tensegrity Footbridge
Journal of Structural Engineering, 2015 Deployable structures are structures that transform their shape from a compact state to an extended in-service position. Structures composed of tension elements that surround compression elements in equilibrium are called tensegrity structures. Tensegrities are good candidates for deployable structures since shape transformations occur by changing ...

Optimal Design of Steel Structures Using Innovative Black Widow Algorithm Hybridized with Greedy Sensitivity-Based Particle Swarm Optimization Technique [PDF]
Journal of Soft Computing in Civil EngineeringThis 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
Computer Assisted Methods in Engineering and Science, 2022 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.
