Download or read book On the design of rockfall protection galleries written by Kristian Schellenberg and published by Sudwestdeutscher Verlag Fur Hochschulschriften AG. This book was released on 2009 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: Galleries are common measures to protect roads and railways from rockfall, which is a relevant natural hazards in mountainous regions. The aim of this research is to provide a better understanding of the dynamic response of rockfall protection galleries in order to improve the prediction accuracy of their impact load capacity. Therefore, an analytical model based on a system of multiple degrees of freedom is proposed. The model allows for a performance based design predicting both, shear and bending failure of the slab structure due to impact. In order to verify and calibrate the model, various tests from small to large-scale were performed. The small-scale tests were used to evaluate the adequate test setup for laboratory research. In midscale tests different cushion layers were evaluated and in particular the performance of the measurement equipment was evaluated. Large-scale tests in a scale 1:2 provided the required data to calibrate the analytical model. In the last series punching tests were performed with different boundary conditions and a smaller loading area.

Available in PDF, EPUB and Kindle. Book excerpt: The construction materials industry is a major user of the world’s resources. While enormous progress has been made towards sustainability, the scope and opportunities for improvements are significant. To further the effort for sustainable development, a conference on Sustainable Construction Materials and Technologies was held at Coventry University, Coventry, U.K., from June 11th - 13th, 2007, to highlight case studies and research on new and innovative ways of achieving sustainability of construction materials and technologies. This book presents selected, important contributions made at the conference. Over 190 papers from over 45 countries were accepted for presentation at the conference, of which approximately 100 selected papers are published in this book. The rest of the papers are published in two supplementary books. Topics covered in this book include: sustainable alternatives to natural sand, stone, and Portland cement in concrete; sustainable use of recyclable resources such as fly ash, ground municipal waste slag, pozzolan, rice-husk ash, silica fume, gypsum plasterboard (drywall), and lime in construction; sustainable mortar, concrete, bricks, blocks, and backfill; the economics and environmental impact of sustainable materials and structures; use of construction and demolition wastes, and organic materials (straw bale, hemp, etc.) in construction; sustainable use of soil, timber, and wood products; and related sustainable construction and rehabilitation technologies.

Available in PDF, EPUB and Kindle. Book excerpt: Developments in Geographic Information Technology have raised the expectations of users. A static map is no longer enough; there is now demand for a dynamic representation. Time is of great importance when operating on real world geographical phenomena, especially when these are dynamic. Researchers in the field of Temporal Geographical Information Systems (TGIS) have been developing methods of incorporating time into geographical information systems. Spatio-temporal analysis embodies spatial modelling, spatio-temporal modelling and spatial reasoning and data mining. Advances in Spatio-Temporal Analysis contributes to the field of spatio-temporal analysis, presenting innovative ideas and examples that reflect current progress and achievements.
