    th The 14 World Conference on Earthquake Engineering October 12-17, 2008, Beijing, China SHOCK CONTROL OF BRIDGES IN CHINA USING TAYLOR DEVICES’ FLUID VISCOUS DEVICES 1 1 2 2 Chen Yongqi Ma Liangzhe Cao Tiezhu1 Robert Schneider Craig Winters 1Beijing Qitai Shock Control and Scientific Development Co.,Ltd , Beijing 100037, China 2Taylor Devices, Inc. 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.

  • China's Major Bridges Summary 1. Background
    China’s Major Bridges Maorun FENG Maorun Feng, born in 1942, graduated from the Tangshan Professor Railway Institute with a Master’s Chairman of Technical degree, has been engaged in the Consultative Committee, design and research of bridges for 40 Ministry of years. He is the Chairman of Technical Consultative Committee Communications and the Former Chief Engineer of the Beijing, China State Ministry of Communications. He is also the current Chairman of China Association of Highway and Waterway Engineering Consultants. [email protected] . Summary In response to continuous economic development over the past 30 years, China has mobilized a program of large scale bridge construction. The technology of various types of bridges, including girder bridges, arch bridges, and cable-supported bridges, has been developed rapidly. Bridge spanning capacity has been continuously improved. Girder bridges with main span of 330 m, arch bridges with main span of 550 m, cable-stayed bridges with main span of 1088 m and suspension bridges with main span of 1650 m have already been built. Moreover, two sea-crossing bridges with overall length over 30 km have also been opened to traffic. This paper briefly introduces China’s major bridges, including girder bridges with spans greater than 200 m, arch bridges with spans greater than 400 m, cable-stayed bridges with spans greater than 600 m, and suspension bridges with spans greater than 1200 m. These bridges represent technological progress in such aspects as structural system, materials, as well as construction methods and equipment. Key words: girder bridge, arch bridge, cable-supported bridge, cable-stayed bridge, suspension bridge, steel-concrete composite bridge 1.

Compared with existing research, we developed an integrated index system that accurately represents the overall effect of the three subsystems of UTA, and a new weight determination method, the structure entropy weight (SEW), was introduced. Then, we constructed a coordinated development index (CDI) of UTA to measure the level of sustainability of new-type urbanization. This study also analyzed trends observed in UTA for 11 cities in Zhejiang Province of China, using statistical panel data collected from 2006 to 2017. The results showed that: (1) urbanization efficiency, the benefits of technological innovation, and air quality weigh the most in the indicator systems, which indicates that they are key factors in the behavior of UTA. The subsystem scores of the 11 cities show regional differences to some extent. (2) Comparing the coordination level of UTA subsystems, we found that the order is: coordination degree of UT > coordination degree of UA > coordination degree of TA.

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.

  • The Shanghai Economic Sphere and Its Evolution As a Mega-Region
    The Shanghai Economic Sphere and its Evolution as a Mega-Region —Geographical Expansion and the Rising Added Value of Shanghai— By Keiichiro Oizumi, Senior Economist Junya Sano, Senior Researcher Center for Pacific Business Studies Economics Department Japan Research Institute Summary 1. This article examines characteristics of economic development of the Shanghai economic sphere, which is defined as consisting of Shanghai Municipality, Jiangsu Province and Zhejiang Province. Income levels in this region are by far the highest in China. 2. With a population of 140 million, the Shanghai economic sphere has a gross re- gional product similar to that of South Korea. At over $5,000, the region’s per capita GRP is close to that of Malaysia. Development has been driven by export-based in- dustrialization. In 2007, the region’s exports were worth $482.0 billion, equivalent to 40% of the total exports of China. This is higher than the total for South Korea. Foreign-owned enterprises are the main driving force behind this performance. In 2007, foreign direct investment reached $40.2 billion. 3. Also significant is the region’s expansion as a consumer market. The Shanghai economic sphere accounts for approximately 20% of total retail sales in China. In urban areas, diffusion rates for televisions, washing machines, refrigerators and other electrical appliances have reached nearly 100%, and ownership of air conditioners, computers and mobile telephones is also rising. It is estimated that over 2 million households in the region have annual incomes in excess of $20,000. 4. Since the 1990s, the economic development of the Shanghai economic sphere has been accelerated by the active involvement of the central government in the de- velopment of the economic sphere, including the Pudong development in Shanghai, and by a continual influx of Japanese and Taiwanese companies in the area around Shanghai under the open-door policy.
