Design Procedures for Footbridges Subjected to Walking Loads: Comparison and Remarks
The Baltic Journal of Road and Bridge Engineering, 2017 This paper aims at pointing out some misconceptions concerning the evaluation of the walking-induced dynamic response of footbridges, and their impact on design procedures. First, a review of the existing Code provisions is briefly presented.

From individual behaviour to an evaluation of the collective evolution of crowds along footbridges
, 2016 This paper proposes a crowd dynamic macroscopic model grounded on microscopic phenomenological observations which are upscaled by means of a formal mathematical procedure.

Modelling human actions on lightweight structures : experimental and numerical developments [PDF]
, 2015 This paper presents recent, numerical and experimental, developments in modelling dynamic loading generated by humans. As modern structures with exposure to human-induced loading, such as footbridges, building floors and grandstands, are becoming ever ...

Identity Play: Middle School Youths' Provisional Self‐Making in Horizon‐Expanding STEM Spaces
Science Education, EarlyView.ABSTRACT This study introduces identity play as an analytic construct for science education to explore improvisational dimensions of middle school students' STEM identity development in multiple out‐of‐school learning experiences focused on environmental problem‐solving.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study
Structural Concrete, EarlyView.Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Pedestrian load models of footbridges
MATEC Web of Conferences, 2017 The increase of vibration problems in modern footbridges shows that footbridges should no longer be designed for static loads only. Not only natural frequencies but also damping properties and pedestrian loading determine the dynamic response of ...

The design of glued laminated timber footbridge structure according to Eurocodes [PDF]
Facta Universitatis. Series: Architecture and Civil Engineering, 2006 The paper presents the conceptual design of the footbridge made of laminated wood. The supporting system of the main bearing elements is made of the laminated wood in the system of arch with three joints and the bridge deck is made of the composite ...

Identification of mass–spring–damper model of walking humans [PDF]
, 2015 Interaction of walking people with vibrating structures is known to be an important yet challenging phenomenon to simulate. Despite of its considerable effects on the structural response, no properly formulated and experimentally verified model currently

I Feel I Need to Think about It: A Defence of Affective Moral Enhancement
Bioethics, Volume 40, Issue 2, Page 175-182, February 2026.ABSTRACT Critics of affective moral enhancement generally contend that moral improvement can only be properly achieved through interventions that engage a person's rational faculties. Therefore, they view attempts to achieve moral improvement by targeting emotions as futile at best and detrimental to moral agency at worst.
