Stochastic Dynamic Analysis of Cultural Heritage Towers up to Collapse
Buildings, 2021 This paper deals with the seismic vulnerability of monumental unreinforced masonry (URM) towers, the fragility of which has not yet been sufficiently studied. Thus, the present paper fills this gap by developing models to investigate the seismic response

Physiological responses to rock climbing in young climbers [PDF]
British Journal of Sports Medicine, 2007 Key questions regarding the training and physiological qualities required to produce an elite rock climber remain inadequately defined. Little research has been done on young climbers. The aim of this paper was to review literature on climbing alongside relevant literature characterising physiological adaptations in young athletes.

Seismic response of rock joints and jointed rock mass [PDF]
, 1996 Long-term stability of emplacement drifts and potential near-field fluid flow resulting from coupled effects are among the concerns for safe disposal of high-level nuclear waste (HLW). A number of factors can induce drift instability or change the near-field flow patterns.

Controls on the geotechnical response of sedimentary rocks to weathering [PDF]
Earth Surface Processes and Landforms, 2019 AbstractWeathering reduces the strength of rocks and so is a key control on the stability of rock slopes. Recent research suggests that the geotechnical response of rocks to weathering varies with ambient stress conditions resulting from overburden loading and/or stress concentrations driven by near‐surface topography.

Proposal for seismic design coefficients for rocking steel braced frame [PDF]
Journal of Structural and Construction Engineering, 2019 Rocking steel braced frames are capable of reducing seismic damage through directing damage in energy dissipation elements. This paper quantifies seismic design factors for the controlled rocking self-centering braced frame including response ...

Rocking vibration with friction
Nihon Kikai Gakkai ronbunshu, 2016 The rocking vibration with friction is focused in this study. The fall down conditions of the rocking system with friction are clarified. Rocking vibration is the rotational motion around the both ends of the structure and occurs when the structure is ...

Inelastic displacement ratio for rocking buildings subjected to far-field and near-field pulse-like ground motions [PDF]
Journal of Structural and Construction Engineering, 2019 Self centering rocking buildings are capable of reducing permanent damage and concentrating damage to replaceable energy dissipation devices. This paper aims to calculate inelastic displacement ratio for self centering rocking buildings under far field ...
