Testing bridge structure vibration using a similarity model

Bridge structures, which account for a large proportion of high-speed railways and urban rail transits, produce vibration that radiate low-frequency structural noise. This low-frequency noise can affect people’s physical and mental health, as well as affect ancient buildings along the line; the manufacture of precision instruments and equipment; and the use of high-precision laboratories. The authors of new paper in the Journal of Aerospace Engineering,...

Modeling storm sewer networks and urban flooding

As heavy precipitation events increase in intensity and frequency, urban flooding wreaks havoc on energy and water services, transportation hubs, housing, education, and employment. Modeling flooding in urban watersheds is challenging because of the spatial variations and interactions between land cover, landscape characteristics, and precipitation that affect the hydrologic response. A new paper in the Journal of Hydrologic Engineering, “Modeling Storm Sewer Networks and Urban...

Designing tall buildings for wind

A new ASCE Manual of Practice brings much-needed consistency to criteria for tall buildings specific to wind effects.

Converting infrastructure systems to geographic information systems

Geographic information systems’ ability to effectively manage and analyze spatial data makes it an ideal means for cities to manage their infrastructure systems.

ASCE paper analyzes construction safety climate with international focus

A new paper uses a standardized tool to compare the safety climate in the Chinese, Australian, and Indonesian construction industries.

ASCE seeks comments on new sustainability standard

ASCE is conducting a public comment period on the new standard activity ASCE/COS 73-XX Standard Requirements for Sustainable Infrastructure, open now through Jan. 18.

Assessing the economic benefits of blue-green infrastructure

Blue-green infrastructure provides multiple benefits to humans and ecosystems, including health and biodiversity, but little data exists on economic benefit.

Free ASCE paper detects SARS-CoV-2 in wastewater

Authors of a new report in the Journal of Environmental Engineering, “SARS-CoV-2 in Detroit Wastewater,” share their first detection in regional wastewater in Detroit, and present methods used.

Exploring the properties of sea sand in sea sand–seawater concrete

With limited availability of freshwater globally, materials engineers have explored using sea sand and seawater in concrete production.

Sustainable procurement: the first step toward sustainable infrastructure

Over the past two decades there has been a push by a range of companies, communities, and governments for a higher level of sustainable infrastructure. However, to achieve sustainable development in infrastructure, you must first procure sustainable goods and services. The International Organization for Standardization defines sustainable procurement as positive environmental, social, and economic impacts possible over the entire life cycle. Considered a business...
