The Angel's Way Route Seaton Sluice to Chester-Le-Street
Northern Saints Trails The Angel’s Way Seaton Sluice to Chester-le-Street 49 kms, 30.5 miles Introduction The Angel’s Way is an important link in the network of the Northern Saints Trails. This route between Seaton Sluice and Chester-le-Street means that there is a continuous 114 mile route between Lindisfarne and Durham, using St Oswald’s Way as far as Warkworth, The Way of the Sea from Warkworth to Seaton Sluice and after The Angel’s Way, Cuddy’s Corse (which is also part of The Way of Learning) from Chester-le-Street to Durham. All the Northern Saints Trails use the waymark shown here. In two parts, from near Holywell to Camperdown and from Bowes Railway Path to West Urpeth, the route follows The Tyne & Wear Heritage Way which is well signed and the waymark is also shown here. The route is divided into 4 sections, 3 of which are between 13 to 14 kilometres or 8 to 8.5 miles in length and section 3 from Millennium Bridge to The Angel of the North is just 8 kilometres or 5 miles. The route is of course named after the iconic Angel of the North designed by Antony Gormley. Since it was erected in 1998, it has quickly become Britain’s best known sculpture. When he designed the sculpture Gormley deliberately angled the wings 3.5 degrees forward to create what he described as “a sense of embrace”. This ties in with the protective concept of the guardian angel and if you want to engage with that theme as you journey on The Angel’s Way, perhaps this prayer will be appropriate: Angel of God, my guardian dear, to whom God’s love commits me here, ever this day, be at my side, to light and guard rule and guide. -

Bridgescape As an Assessment Tool in the Socio- Spatial and Visual Connections of the Central Urban Areas of Newcastle and Gateshead
Special Issue, | Roadscape, 8(36) Bridgescape as an Assessment Tool in the Socio- spatial and Visual Connections of the Central Urban Areas of Newcastle and Gateshead Goran Erfani Abstract | Newcastle University, UK Growing roads and mobility have led to the formation of new landscape types: known bridgescape or bridge landscape. The social, [email protected] cultural, and visual impacts of bridges on their surroundings as drivers and symbols of the development have gained increasing significance in roadscape studies. This article aims to assess the role and design of bridges in the socio-spatial and visual connections of the central urban areas of Newcastle and Gateshead, located in North East England, by the criterion of the bridgescape. The findings of this article show that bridges are not only transitional passages; rather, they can be socio-spatial destinations for people to meet, do collective activities and improve their environmental perceptions. In urban milieu, landmarks have dissimilar impacts on visual connections and bridgescape. Characteristic and contrasting landmarks improve bridgescapes; however, corrupting landmarks have a destructive role in bridgescape. Keywords | Bridgescape (bridge landscape), Socio-Spatial Connections, Visual Connections. 32 No.36 Autumn 2016 Goran Erfani Introduction | Bridges are a vital element in ground from landscape architects to structural engineers. transportation networks, which connect cities, communities In North east England, the city of Newcastle-upon-Tyne, and even nations. Within urban areas, bridges not only have a commonly known as Newcastle, is well-known for its key role in the spatial connection of places but also can facilitate bridgescape.

North Tonawanda, NY 14120, USA Email: [email protected], ABSTRACT : Fluid Viscous Devices are a successful structural protective system for bridge vibration. The structural protective technique and the dampers have been introduced to China since 1999. The Taylor Devices’ damper systems has already been successfully installed or will be installed in large or the super large bridges in China for protection from earthquake, wind. vehicle and other vibration. Seventeen different bridge projects introduced here include the Sutong Yangtze River Bridge, the longest cable stayed bridge in the world, the Nanjing 3rd Yangtze River Bridge, the fifth longest suspension bridge in the world, and the Xihoumen Across Sea Bridge, the second longest suspension bridge in the world. The performance of the bridges and dampers have been reported as “very good” during the May 12, 2008 Wenchuan earthquake. All of the dampers produced have been subjected to rigorous static and dynamic testing, which show the dampers will perform well for the next 50 years and possibly a lot longer. KEYWORDS: Lock-Up Devices, Fluid Viscous Dampers, Limited Displacement Damper 1. INTRODUCTION Along with the rapid economic development in China over the past two decades, a large number of highways and bridges have been built in China. By 2004 China constructed 1.81 millions kilometers of roads and 30 thousand kilometers of highways. -

Sherif A. Mourad 4 STR403 - Metallic Bridges Winter 2020 2 Definition of a Bridge A bridge is a structure that carries a service (which may be highway or railway traffic, a footpath, public utilities, etc.) over an obstacle (which may be another road or railway, a river, a valley, etc.), and then transfers the loads from the service via the superstructure through the bridge substructure to the foundation level. Sherif A. Mourad 5 Definition of a Bridge Sherif A. Mourad 6 STR403 - Metallic Bridges Winter 2020 3 Historical background The historical development of bridges best illustrates the progress of structural engineering from ancient times up to the present century. In particular the development in steel bridges equates with the progress in structural analysis, theory of strength of materials and materials testing, since all of them were increasingly stimulated by the need for bridging larger spans and building more economically with the new construction method. Sherif A. Mourad 7 Historical background The simplest type of a bridge is stepping stones, so this may have been one of the earliest types. -

This is an open access article distributed under the Creative Commons Attribution License, which permits unrestricted use, distribution, and reproduction in any medium, provided the original work is properly cited. To study the vehicle load characteristics of bay bridges in China, especially truck loads, we performed a statistical analysis of the vehicle loads on Hangzhou Bay Bridge using more than 3 months of weigh-in-motion data from the site. The results showed that when all the vehicle samples were included in the statistical analysis, the histogram of the vehicles exhibited a multimodal distribution, which could not be fitted successfully by a familiar single probability distribution model. When the truck samples were analyzed, a characteristic multiple-peaked distribution with a main peak was obtained. The probability distribution of all vehicles was fitted using a weighting function with five normal distributions and the truck loads were modeled by a single normal distribution. -
