Improving seismic performance

Bulletin of the New Zealand Society for Earthquake Engineering, 2008
Structural engineers typically improve the seismic performance of deficient structures by adding strengthening elements to the structural system, which also add stiffness to the structure. However, as performance based design becomes more common practice, the focus is on the total performance of not only the structural system but the building ...

SEISMIC PERFORMANCE OF BUILDINGS DESIGNED BY CURRENT SEISMIC CODE

Journal of Structural and Construction Engineering (Transactions of AIJ), 2009
In this paper, the dynamic analysis of buildings considering soil-structure interaction whose base shears was defined by Calculation of Lateral Load Carrying Capacity and Calculation of Response and Limit Strength depending on the design ductility of buildings was conducted.

English teachers' journeys since the 2020 Iteration of Black Lives Matter

British Educational Research Journal, EarlyView.
Abstract The 2020 resurgence of Black Lives Matter (BLM) mobilised students in England to demand greater representation of racially minoritised voices in English curriculums—a call highlighted by stark inequity: just 1.5% of GCSE texts studied are by racially minoritised authors, despite racially minoritised students comprising 38.0% of the student ...

Method to improve seismic performance: Selection of key components and multi-objective optimization of risk and cost

Nuclear Engineering and Technology
Considering the increasing frequency of large-scale earthquakes worldwide, ensuring the seismic safety of nuclear power plants against earthquakes exceeding the design conditions is essential. Therefore, this study proposed a method for enhancing seismic

A method of seismic performance evaluation based seismic fragility analysis

MATEC Web of Conferences, 2018
For evaluating seismic performance of structures, a method is presented based on increment dynamic analysis and seismic fragility analysis. Firstly, the failure probability equation is deduced, in which the relationships of seismic intensities and ...

Shaking Table Tests of Lead Inserted Small-Sized Laminated Rubber Bearing for Nuclear Component Seismic Isolation

Applied Sciences, 2021
To assure seismic isolation performance against design and beyond design basis earthquakes in the nuclear facility components, the lead inserted small-sized laminated rubber bearings (LRB), which has a 10 kN vertical design load, have been designed and ...

Resolving the biome debate: ecological and palaeo‐data concur that the extensive tree‐limited grassy biomes of central and north‐western Madagascar are largely anthropogenic

Biological Reviews, EarlyView.
ABSTRACT For millennia, human activities have transformed ecosystems globally. Determining which landscapes are predominantly anthropogenic is crucial to conservation and habitat restoration. Madagascar, a critically‐threatened biodiversity hotspot, is a prominent example.

Centrifuge modeling of rocking-isolated inelastic RC bridge piers [PDF]

, 2014
Experimental proof is provided of an unconventional seismic design concept, which is based on deliberately underdesigning shallow foundations to promote intense rocking oscillations and thereby to dramatically improve the seismic resilience of structures.
