One of the main goals of a good and effective structural design is to decrease, as far as possible, the self-weight of structures, because they must carry the service load. This is especially important for reinforced concrete (RC) structures, as the self-weight of the material is substantial. For RC structures it is furthermore important that the whole structure or most of the structural elements are under compression with small eccentricities. Continuous spatial concrete structures satisfy the above-mentioned requirements. It is shown in this book that a span of a spatial structure is practically independent of its thickness and is a function of its geometry. It is also important to define which structure can be called a spatial one. Such a definition is given in the book and based on this definition, five types of spatial concrete structures were selected: translation shells with positive Gaussian curvature, long convex cylindrical shells, hyperbolic paraboloid shells, domes, and long folders.
To demonstrate the complex research, results of experimental, analytical, and numerical evaluation of a real RC dome are presented and discussed. The book is suitable for structural engineers, students, researchers and faculty members at universities.

Tall Building Design Guidelines - City of Toronto.
Author(s)/Editor(s): HOK Architects & Urban Strategies Inc. | Size: 9,02 MB | Format:PDF | Quality:Unspecified | Publisher: City of Toronto. | Year: 2013 | pages: 91
This updated city-wide "Tall Buildings Design Guidelines" document integrates and builds upon these previous studies and guidelines to establish a new, unified set of performance measures for the evaluation of all tall building development applications across the entire city.
To assist with implementation of Official Plan policy and provide specific design direction for tall buildings in Toronto, City Council adopted the "Design Criteria for the Review of Tall building Proposals" (2006) and the "Downtown Tall Buildings Vision and Performance Standards Design Guidelines" (2012). These guidelines were developed through consultant studies by HOK Architects (2006) for the city-wide "Design Criteria," and Urban Strategies Inc./Hariri Pontarini Architects (2010) for the "Downtown Guidelines."

The TVSdesign concept for the landmark "Dubai Towers- Dubai" is the centerpiece for "The Lagoons," a new urban development in Dubai, UAE. The four towers, ranging from 57 to 88 floors atop a nine level podium, are clustered to form a choreographed sculpture, representing the movement of candlelight.
The dramatic Dubai Towers, visible from extended distances, will combine in form to represent the future of Dubai and its innovative achievements. The architectural expressions are guided by a sophisticated aesthetic along with structural and engineering triumphs unmatched by any modern structure. The buildings will serve residential, commercial, retail and hospitality purposes.
Strategically located on the extension of the Dubai Creek, the project centers on concepts of environment, conservation parkland and open spaces. The island community is located next to the Ras Al Kror Wildlife Sanctuary and is one of the first projects in Dubai undergoing an Integrated Environmental Impact Assessment (EIA) following international standards across all phases of the project. Culture will also be a big focus with the construction of a planetarium, museum, art center, theatre and opera house.

Based on a discussion of conflicts in the urbanization process, this book provides theoretical and practical solutions for the preservation and development of urban localities. On the basis of informative case studies, it reveals the similarities and unique aspects of urbanization in Germany and China. The process of urban growth and the future trend of locality and urbanization are also examined. The book gathers contributions from architects, landscape designers, environmental engineers, urban planners and geographers, who analyze urban issues from their individual perspectives and provide methods for preserving and developing urban localities. As such, it expresses responses to urban development trends against the backdrop of sustainability in the 21st century.

INDIAN - HANDBOOK ON SEISMIC RETROFIT OF BUILDINGS (2007).
Author(s)/Editor(s): CENTRAL PUBLIC WORKS DEPARTMENT & INDIAN BUILDING CONGRESS | Size: 22,8 MB | Format:PDF | Quality:Unspecified | Publisher: Central Public Works Department, India. | Year: 2007 | pages: 618
Many existing buildings do not meet the seismic strength requirement. The need for seismic retrofitting in existing building can arise due to any of the following reasons:
1) building not designed to code.
2) subsequent updating of code and design practice.
3) subsequent upgrading of seismic zone.
4) deterioration of strength and aging.
5) modification of existing structure.
6) change in use of the building, etc.
In India, almost 85% of total buildings are nonengineered buildings made up of earthen walls, stone walls, brick masonry walls, etc.
This Handbook has been envisaged to address this serious and widespread problem of seismic vulnerability of buildings. The Handbook covers the seismic retrofitting of both engineered and non-engineered buildings.

Huge earthquakes and tsunamis have caused serious damage to important structures such as civil infrastructure elements, buildings and power plants around the globe. To quantitatively evaluate such damage processes and to design effective prevention and mitigation measures, the latest high-performance computational mechanics technologies, which include telascale to petascale computers, can offer powerful tools. The phenomena covered in this book include seismic wave propagation in the crust and soil, seismic response of infrastructure elements such as tunnels considering soil-structure interactions, seismic response of high-rise buildings, seismic response of nuclear power plants, tsunami run-up over coastal towns and tsunami inundation considering fluid-structure interactions. The book provides all necessary information for addressing these phenomena, ranging from the fundamentals of high performance computing for finite element methods, key algorithms of accurate dynamic structural analysis, fluid flows with free surfaces, and fluid-structure interactions, to practical applications with detailed simulation results. The book will offer essential insight for researchers and engineers working in the field of computational seismic/tsunami engineering.

The book is an attempt to introduce Chinese gardens in various cities from unique professional perspectives, demonstrating the exquisiteness of traditional gardens in an effort to present the skilful and elaborate designs. The Chinese gardens presented here are classified in three categories: Traditional Chinese private gardens, Historic Chinese gardens in modern time, and Newly-built Chinese gardens. Traditional Chinese private gardens value harmony between man and nature.
