A aplica o do sistema de paredes de cisalhamento em edif cios de bet o armado (RC) tem vindo a ser amplamente utilizada para minimizar as consequ ncias s smicas. O artigo apresenta o estudo param trico em termos de deslocamentos, deriva de andares e compara o de cisalhamento de base para diferentes localiza es de paredes de cisalhamento no edif cio. Os resultados s o nicos e teis para aten o futura. Este artigo centra-se no efeito da localiza o da parede de corte num edif cio de v rios andares. Considera-se um edif cio em planta de estrutura G+10 (11 andares) com uma dimens o de base de 24m X 24m e uma altura de piso t pica de 3,3m. No presente trabalho, um edif cio de 11 andares foi modelado com recurso a um software e foram estudados dois modelos diferentes com diferentes localiza es de paredes de corte na estrutura do edif cio para par metros cr ticos como o deslocamento e o corte na base sob carga lateral. A an lise foi efectuada utilizando o software ETABS e, para a an lise, foi utilizado o m todo do coeficiente s smico. Foram analisados dois tipos de modelos (um com parede de cisalhamento colocada no meio de 4 lados perif ricos e outro com parede de cisalhamento colocada em 4 cantos em forma de L).

Die Anwendung von Scherwandsystemen in Stahlbetongeb uden ist weit verbreitet, um die Folgen von Erdbeben zu minimieren, und die vorliegende Literatur konzentriert sich auf zwei verschiedene Modelle mit Scherw nden an unterschiedlichen Positionen. Der Artikel zeigt die parametrische Studie in Bezug auf die Verschiebung, die Geschossdrift und den Vergleich der Basisscherung f r verschiedene Positionen der Scherwand im Geb ude. Die Ergebnisse sind einzigartig und fruchtbar f r zuk nftige Untersuchungen. In diesem Beitrag werden die Auswirkungen der Lage der Scherwand in einem mehrst ckigen Geb ude untersucht. Es wird ein in der Ebene liegendes Geb ude von G+10 (11 Stockwerke) mit einer Grundfl che von 24 m x 24 m und einer typischen Geschossh he von 3,3 m betrachtet. In der vorliegenden Arbeit wurde ein mehrst ckiges Geb ude mit Hilfe einer Software modelliert und zwei verschiedene Modelle mit unterschiedlichen Positionen der Scherw nde im Geb uderahmen f r kritische Parameter wie Verschiebung und Grundscherung unter seitlicher Belastung untersucht. Die Analyse wurde mit der Software ETABS durchgef hrt und f r die Analyse wurde die Methode des seismischen Koeffizienten verwendet. Zwei Arten von Modellen (eines mit einer Scherwand, die in der Mitte von 4 Umfangsseiten angeordnet ist, eines mit einer Scherwand, die an 4 Ecken in L-Form angeordnet ist) wurden analysiert.

L'applicazione del sistema di pareti a taglio negli edifici in cemento armato (RC) ormai ampiamente diffusa per minimizzare le conseguenze sismiche. La presente letteratura si concentra su due diversi modelli con pareti a taglio in posizioni diverse. L'articolo illustra lo studio parametrico in termini di spostamento, deriva dei piani e confronto del taglio alla base per la diversa posizione delle pareti a taglio nell'edificio. I risultati sono unici e utili per l'attenzione futura. Il presente lavoro si concentra sull'effetto della posizione delle pareti di taglio in un edificio a pi piani. Si prende in considerazione un edificio in pianta di G+10 (11 piani) con dimensioni di base di 24 m X 24 m e un'altezza tipica del piano di 3,3 m. In questo lavoro, un edificio a pi piani stato modellato utilizzando un software e due diversi modelli sono stati studiati con una diversa posizione delle pareti di taglio nel telaio dell'edificio per parametri critici come lo spostamento e il taglio alla base sotto carico laterale. L'analisi stata condotta con il software ETABS e per l'analisi stato utilizzato il metodo dei coefficienti sismici. Sono stati analizzati due tipi di modelli (uno con parete di taglio posizionata al centro dei 4 lati periferici e uno con parete di taglio posizionata ai 4 angoli a forma di L).

Zastosowanie systemu ścian ścinanych w budynkach żelbetowych (RC) stalo się szeroko stosowane w celu zminimalizowania skutk w sejsmicznych. Niniejsza literatura koncentruje się na dw ch r żnych modelach ze ścianami ścinanymi w r żnych pozycjach. W artykule przedstawiono badania parametryczne w zakresie przemieszczenia, dryfu kondygnacji i por wnania ścinania podstawy dla r żnych lokalizacji ściany ścinanej w budynku. Wyniki są unikalne i owocne dla przyszlej uwagi. Niniejszy artykul koncentruje się na wplywie polożenia ściany ścinanej w budynku wielopiętrowym. Rozważany jest plaski budynek o konstrukcji G + 10 (11 kondygnacji) o wymiarach podstawy 24 m x 24 m i typowej wysokości podlogi 3,3 m. W niniejszej pracy piętrowy budynek zostal zamodelowany przy użyciu oprogramowania i zbadano dwa r żne modele z r żnymi lokalizacjami ścian ścinanych w ramie budynku pod kątem krytycznych parametr w, takich jak przemieszczenie i ścinanie podstawy pod obciążeniem bocznym. Analiza zostala przeprowadzona przy użyciu oprogramowania ETABS, a do analizy wykorzystano metodę wsp lczynnika sejsmicznego. Przeanalizowano dwa typy modeli (jeden ze ścianą ścinaną umieszczoną pośrodku 4 bok w obwodowych, drugi ze ścianą ścinaną umieszczoną w 4 narożnikach w ksztalcie litery L).

The application of the shear wall system in reinforced concrete (RC) buildings has become widely used to minimize seismic consequences.The present literature focuses on two different models with shear walls at different positions. The article showcases the parametric study in terms of displacement, storey drift, and base shear comparison for different location of shear wall in the building. The results are unique and fruitful for future attention. This paper focuses to see the effect of shear wall location in a multi-storied building. An in-plane building of G+10 (11 storey) structure having base dimension of 24m X 24m with typical floor height of 3.3m is considered. In this present work, a storied building was modeled using software and two different models were studied with different location of shear walls in building frame for critical parameters like displacement and base shear under lateral loading. The analysis has been carried out using the ETABS software and for analysis, seismic coefficient method is used. Two types of models (one with shear wall placed at middle of 4 periphery sides, one with shear wall placed at 4 corners in L shape) have been analyzed.

This open access book presents deep investigation to the manifold topics pertaining to global university collaboration. It outlines the strategies King Abdulaziz University has employed to rise in global rankings, and the reasons chosen to collaborate with other academic and research institutes. The environment in which universities currently exist is considered, and subsequently how an innovative culture might be established and maintained to enable global partnerships to be implemented and to succeed is discussed. The book provides an intense focus on why collaboration is a necessary ingredient for knowledge transfer and explains how to do it. The last part of the book considers how to sustain partnerships. This is because one of the challenges of global partnerships is not just setting them up, but also sustaining them.

This book explains, in a simple and practical way, how and when the diabetic patient should conduct self-management activities. These include healthy eating, physical activity, the consumption of medication, the monitoring of blood glucose level, the cessation of smoking, and foot care, among others. Such activities can help the patient to establish a level of control over their condition, and thus reduce the risk of developing serious complications. As such, this book will be of particular interest to diabetic patients and their family members, as it will provide them with further information in their fight against diabetes. Additionally, it will also appeal to physicians, pharmacists and nurses as a guide for their work in educating diabetic patients.
