Influence Of Lateral Load Distributions On Pushover Analysis Effectiveness
AIP Conference Proceedings, 2008 The effectiveness of two simple load distributions for pushover analysis recently proposed by the authors is investigated through a comparative study, involving static and dynamic analyses of seismic response of eccentrically braced frames. It is shown that in the upper floors only multimodal pushover procedures provide results close to the dynamic ...

Jianzhu Gangjiegou Jinzhan, 2019 为克服传统Pushover方法的局限性,提出了基于能量平衡的位移自适应多模态Pushover方法。这种方法结合了能量平衡方法和位移自适应Pushover方法,对所考虑的各个振型分别进行Pushover分析,然后将所得各个模态性能点处对应的各向性能指标按SRSS组合规则进行组合。这种方法可以考虑高阶振型影响以及结构屈服以后侧向力分布的变化,同时也避免了传统基于位移自适应Pushover方法无法反映高阶振型影响以及Pushover分析中侧向力折返问题。为验证所提出方法的预测效果,选取3个高层钢框架作为案例 ...

Journal of Materials and Engineering Structures, 2023 In current study, Damage estimation is carried out using new methodology using parameters such as absorbed energy and degrading stiffness by pushover analysis. A new stiffness-based damage index is developed for each increasing step of pushover analysis,

Buildings, 2019 It is essential for the seismic design of a base-isolated building that the seismic response of the superstructure remains within the elastic range. The evaluation of the maximum seismic member force in a superstructure is thus an important issue.

How can children and young people have a voice in urban treescapes?
People and Nature, EarlyView.Abstract Scientific understanding of climate change has, to date, failed to result in sufficient action. This paper proposes that a deficit model of top‐down learning and dissemination in relation to public engagement with science may be part of the problem, particularly when considering the attitudes, values and empowerment of children and young ...

Heterogeneous preferences for use and non‐use values provided by insects
People and Nature, EarlyView.Abstract Public support is essential for reversing insect declines, yet conservation efforts often focus on instrumental values, particularly pollination and pest regulation, while overlooking the many and varied cultural ecosystem services that may underpin broader public support for conservation.

Robust β‐myrcene block copolymer elastomeric vitrimers
Polymer International, EarlyView.Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...
