4971.加筋土墙的极限平衡性能和抗压能力比较
[建筑业,黑色金属冶炼和压延加工业] [2015-08-06]
The paper is focused on issues related to the behavior of reinforced soil walls at working stress and near failure, and the prediction accuracy of internal stability working stress and limit equilibrium (LE) design methods. The paper identifies the key variables, principles and assumptions that affect the accuracy of these methods considering the full range of conditions from working stress to failure. The strain at peak strength of a granular soil wall backfill is identified as a key parameter for understanding the differences between working stress and LE design methods. Both geosynthetic and steel reinforced wall systems are examined using measured reinforcement strain and loads taken from full-scale walls under both working stress (operational) conditions and at incipient collapse (failure).

[建筑业,水利、环境和公共设施管理业] [2015-08-05]
Between September 18th and October 13th, 2012, National Institute for Occupational Safety and Health (NIOSH) researchers and the Silica/Milling-Machines Partnership coordinated by the National Asphalt Pavement Association (NAPA) conducted field testing of a local exhaust ventilation system (LEV) on a Roadtec RX600e cold milling machine. The tests included ten days of air sampling across seven different highway construction sites in Indiana. At each site, full-shift personal breathing zone samples for respirable crystalline silica were collected from the operator and ground man during the course of normal employee work activities of asphalt pavement milling.

4975.全球零能耗建筑市场报告（2015-2019年）
[建筑业] [2015-07-25]
Zero-energy buildings consume only as much energy as they generate within a year. They are the next target for green building construction and modification over the next several years. Green building practices have become more common in the global construction industry. The aim is to utilize only as much energy as buildings produce onsite through renewable energy systems.

4976.全球建筑涂料市场报告（2015-2019年）
[化学原料和化学制品制造业,建筑业] [2015-07-24]
Coatings are products used to protect a surface and/or enhance its appearance. Architectural coatings are applied to commercial and residential buildings. They protect a building from elements such as moisture, UV radiation, and microbes. Paints, primers, lacquers, varnishes, and stains are some of the major types of architectural coating products. These products are formulated using various types of resins such as acrylic, alkyds, polyester, and polyurethane. The market may be broadly classified by the two major types of coating technologies into solventborne and water-borne coatings.

4977.全球基于聚合物的热界面材料(TIM)市场报告（2015-2019年）
[建筑业,化学原料和化学制品制造业] [2015-07-24]
TIM are used to support heat sinks in removing heat from heat sources in various types of equipment. They are used in the form of secondary thermally conductive materials to replace the thermally insulating air between two surfaces. Besides helping in the efficient transfer of heat, TIM also act as adhesives and strengthen the mechanical link between surfaces. Polymer-based TIM are the most commonly used TIM and owing to their superior conductive and adhesive properties, find extensive usage for thermal management applications in various industries, including computer, electrical and electronics, telecom, and automotive.

4978.建筑物中的舒适度控制
[建筑业,水利、环境和公共设施管理业] [2015-07-17]
As most of the time people develop their daily activities inside buildings this energy saving cannot be obtained by putting users' welfare to risk, since their productivity is directly related to their comfort. Thus, it is necessary to look for a tradeoff between users' comfort and energy saving. In order to achieve this compromise, the construction of bioclimatic buildings which incorporate passive strategies and make use of renewable energies is one of the most applied approaches. Nevertheless, in some cases, and mainly due to the typical climate of the place where the building is located, it may be insufficient. In these cases, it is required, together with innovations in structural designs, to perform specific control actions on HVAC systems and other building's actuators, oriented to provide comfortable environments from thermal, visual and indoor air quality points of view, and with the minimum energy consumption.

4979.美国建筑专家会议：燃烧安全性
[建筑业,水利、环境和公共设施管理业,电力、热力、燃气及水生产和供应业] [2015-07-16]
This is a meeting overview of 'The Best Approach to Combustion Safety in a Direct Vent World', held June 28, 2012, in San Antonio, Texas. The objective of this Expert Meeting was to identify gaps and barriers that need to be addressed by future research, and to develop data-driven technical recommendations for code updates so that a common approach for combustion safety can be adopted by all members of the building energy efficiency and code communities. The DOE BA program focuses on reducing energy consumption in the nation's housing stock through smart integration of energy efficient design and upgrades. The target is 30%-50% energy savings captured through the application of many measures, including reduction in air infiltration, equipment upgrades, smart controls, and thermal envelope improvements.

4980.屋顶节省计算器集合体的可视化分析
[信息传输、软件和信息技术服务业,建筑业] [2015-07-16]
Using a database of over 3 million RSC simulations for different combinations of parameters, we have built a visual analytics tool to assist in the exploration and identification of features in the data. Since the database contains multiple variables, both categorical and continuous, we employ a coordinated multi-view approach that allows coordinated feature exploration through multiple visualizations at once. The main component of our system, a parallel coordinates view, has been adapted to handle large-scale, mixed data types as are found in RSC simulations. Other visualizations include map coordinated plots, high dynamic range (HDR) line plot rendering, and an intuitive user interface. We demonstrate these techniques with several use cases that have helped identify software and parametric simulation issues.
