Beijing Record: A Physical and Political History of Planning Modern Beijing
Author(s)/Editor(s): Jun Wang | Size: 146 MB | Format:PDF | Quality:Original preprint | Publisher: World Scientific | Year: 2011 | pages: 536 | ISBN: 9814295728
In 2003, the Chinese Xinhua News Agency journalist Wang Jun published the bestseller "Beijing Record", the result of ten years of research on the urban transformation of Beijing in the last fifty years. Home to more than 15 million people, this ancient capital city - not surprisingly - has a controversial, complicated history of planning and politics, development and demolition. The publication raises a number of unsettling questions: Why has a valuable historical architecture such as city ramparts, gateways, old temples, memorial archways and the urban fabric of hutongs (traditional alleyways) and siheyuan (courtyard houses) been visibly disappearing for decades? Why are so many houses being demolished at a time of economic growth? Is no one prepared to stand up for the preservation of the city? For his research, Wang went through innumerable archives, read diaries and collected an unprecedented quantity of data, accessing first-hand materials and unearthing photographs that clearly document the city's relentless, unprecedented physical makeover. In addition, he conducted more than 50 in-person interviews with officials, planners, scholars and other experts. Wang's publication presents a survey of the main developments and government-level (both central and municipal) decisions, devoting a lot of attention to the 1950s and 1960s, when Beijing experienced a critical wave of transformative events. Shortly after its publication by SDX joint Publishing Company House in October 2003, "Beijing Records" ignited a firestorm of debate and discussion in a country where public interaction over such a sensitive subject rarely surfaces.

Abstract: In recent decades, shear walls and tube structures have been the most appropriate structural forms for the construction of high-rise concrete buildings. Thus, recent Reinforced Concrete (RC) tall buildings have more complicated structural behaviour than before. Therefore, studying the structural systems and associated behaviour of these types of structures is very important. The main objective of this paper is to study the linear and nonlinear behaviour of one of the tallest RC buildings, a 56-storey structure, located in a high seismic zone in Iran. In this tower, shear wall systems with irregular openings are utilized under both gravity and lateral loads and may result in some especial issues in the behaviour of structural elements such as shear walls and coupling beams. The analytical methodologies and the results obtained in the evaluation of life-safety and collapse prevention of the building are also discussed. The weak zones of the structure based on the results are introduced, and a detailed discussion of some important structural aspects of the high-rise shear wall system with consideration of the concrete time dependency and constructional sequence effects is also included.

The book contains the invited keynote and theme lectures presented at the 4th International Conference on Geotechnical Earthquake Engineering (4ICEGE). The conference was held in Thessaloniki, Greece, from 25 to 28 June, 2007, and was organized by the Technical Committee of Earthquake Geotechnical Engineering (TC4) of the International Society of Soil Mechanics and Geotechnical Engineering (ISSMGE), the Hellenic Scientific Society of Soil Mechanics and Geotechnical Engineering and the Laboratory of Soil Dynamics and Geotechnical Earthquake Engineering of Aristotle University of Thessaloniki.
It provides a comprehensive overview of the progress achieved to date in soil dynamics and geotechnical earthquake engineering, as well as in engineering seismology and seismic risk assessment and management. In situ and laboratory testing, theoretical issues and numerical modeling of soil dynamics, seismic hazard with emphasis on the long-period ground motion displacements, site effects and microzonation, liquefaction assessment and mitigation, soil-structure interaction, performance based design of geotechnical structures, earthquake resistant design and performance of shallow and deep foundations, retaining structures, embankments and dams, underground structures and lifelines, are all among the different topics covered in this book. Interdisciplinary subjects such as vulnerability assessment of, transportation networks and lifelines as well as of geotechnical structures are also discussed. Finally, the book provides a thorough presentation of the existing worldwide important large-scale testing facilities and geotechnical strong ground motion arrays.
The book is organized in nineteen chapters written by distinguished experts and includes the 2nd Ishihara Lecture given by Prof. Izzat M. Idriss in honor of Prof. Kenji Ishihara. The aim is to present the current state of knowledge and engineering practice, addressing recent and ongoing developments while also projecting innovative ideas for future research and development.
Audience
Earthquake geotechnical and structural engineers, civil engineers, geologists, geophysicists and seismologists will find in this book the most recent advances in soil dynamics, earthquake and geotechnical engineering, as well as their interfaces with geology, geophysics and engineering seismology. It is of interest not only to scientists, engineers and students, but also to those interested in earthquake hazard assessment and mitigation.

Abstract: It is the first upload of any real time DEA report in CivilEA or any other civil engineering forums. All the effort goes to our assessor and who complied this report as per our guideline and code prescribed rules. I have dedicated this report to all structural engineer who are working to ensure the safety of any building or structure. Also put your valuable comments so that we can upgrade the report standard.
On 14 December 2013, ARUP carried out a visual structural survey of this project. They have major concern about the following conditions in a factory building.
Design check all columns, beams and slabs. Create loading plans and heights to match actual structural code capacity.
Mezzanine: Uncontrolled loading on cantilever
Mezzanine: Plan and height restrictions to be introduced to prevent future overloading. (Loading plans in line with design loads from engineer)
We carried out a Detailed Engineering Assessment of this structure especially considering the conditions described above and step by step carried out the remediation criteria.
A detailed calculation and analysis has been described in the rest of the report.

Concrete structures often suffer from cracking that leads to much earlier deterioration than designed service life. To prevent such deterioration, regular inspection of cracks in concrete structures and their repair are usually carried out by means of some kind of human intervention.
Once cracking occurs in reinforced concrete members, not only is the stiffness reduced but steel bars corrosion also occurs due to the permeation of rain and aggressive substances, reducing structural safety and serviceability. In order to avoid the dangerous situations caused by such deterioration, application of proper maintenance systems is required.
Self-healing, or autogenous healing, of concrete and reinforced concrete is a phenomenon that has been studied by various researchers. Reviews on healing of cracks can be found for example in Lauer & Slate (1956), Jacobsen et al. (1998) and de Rooij & Schlangen (2011).
Many experimental results and practical experiences have demonstrated that cracks in concrete have the ability to heal themselves, reducing water flow through cracks over time.

The ever-increasing traffic demands, coupled with deteriorating condition of bridge structures, present great challenges for maintaining a healthy transportation network. The challenges encompass a wide range of economic, environmental, and social constraints that go beyond the technical boundaries of bridge engineering. Those constraints compound the complexity of bridge projects and motivate innovations in bridge engineering technology towards the design and construction of sustainable bridges. The sustainability aims at minimizing the cost of bridge construction projects and the associated environmental impact on the society, while maintaining healthy economic development.
On August 24–25, 2015, bridge engineers from all over the world gathered at the 8th New York City Bridge Conference to discuss and share experiences on the construction and maintenance of sustainable bridge structures.
This volume contains a selection of papers that were presented at the conference. The peer-reviewed papers are valuable contributions to the state of the art in bridge engineering and of archival quality.
