Analysis of free in-plane vibrations of a rectangular plate with various boundary conditions canonical form using the modified Riley-Ritz method

Results in Engineering
This paper investigates the free in-plane vibrations of rectangular sheets under various boundary conditions using an improved Riley-Ritz method. A novel approach involving graph theory and canonical forms is introduced, marking a first in the study of ...

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 ...

Experimental Study on the Behavior of Existing Reinforced Concrete Multi-Column Piers under Earthquake Loading

Applied Sciences, 2021
When a seismic force acts on bridges, the pier can be damaged by the horizontal inertia force of the superstructure. To prevent this failure, criteria for seismic reinforcement details have been developed in many design codes.

Optimizing Strategies for Non‐Invasive Prospection of Settlements in the Intertidal Zone: A Case Study From the Centre of the Drowned Medieval Village of Tolsende (Scheldt Estuary, the Netherlands)

Archaeological Prospection, EarlyView.
ABSTRACT Medieval and early modern drowned villages in the intertidal zone of the Scheldt estuary (the Netherlands) constitute intriguing yet largely understudied components of north‐western Europe's underwater cultural heritage. Despite their high archaeological potential as time capsules of past settlement landscapes, research has remained limited ...

Scanning Parametric Sediment Echosounder as Tool for Underwater Archaeological Prospection

Archaeological Prospection, EarlyView.
ABSTRACT Underwater cultural heritage 3D prospection techniques, especially for remains that are partly buried in the ground, are only very rarely available and often can only be applied with considerable technical effort. To overcome this limitation, we evaluate a methodological adaption of widely used and available single channel parametric sediment ...

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 ...
