This Standard provides requirements for the design of guyed and self-supporting latticed steel electrical transmission structures. The requirements are applicable for hot-rolled and cold-formed steel shapes. Analysis techniques are outlined for the geometrical configurations currently in use. Procedures for the design of individual members reflect extensive experience and test data on steels with yield points up to 65 ksi. Connection design procedures allow the engineer to match connection capability to the most suitable end and edge distances for detailing. If full-scale structure testing...

Prepared by the Wind Tunnel Testing for Buildings and Other Structures Standards Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE.
Wind Tunnel Studies for Buildings and Other Structures, Standard ASCE/SEI 49-12, provides the minimum requirements for conducting and interpreting wind tunnel tests to determine wind loads on buildings and other structures. Wind tunnel tests are used to predict the wind loads and responses of a structure, structural components, and cladding to a variety of wind conditions. This Standard...

When a magnitude 8.8 earthquake occurred off the coast of Chile on February 27, 2010, it affected 80 percent of Chile's population. Damage to lifelines was caused by strong ground shaking, permanent ground deformation, lateral spread, and a tsunami in the coastal areas of Bio Bio and Maule. Lifeline services were significantly disrupted for the first week, at a considerable cost to Chile's economy.

This TCLEE report discusses in detail the effects of the earthquake, as observed by an ASCE-TCLEE...

Prepared by the Flood Resistant Design and Construction Committee of the Codes and Standards Activities Division of the Structural Engineering Institute of ASCE

Flood Resistant Design and Construction, ASCE/SEI 24-14, provides minimum requirements for design and construction of structures located in flood hazard areas and subject to building code requirements. Identification of flood prone structures is based on flood hazard maps, studies, and other public information. This standard applies to new structures, including subsequent work, and to work classified as substantial...

Guidelines for Operational Hail Suppression Programs, ANSI/ASCE/EWRI 39-15, describes the process for designing, conducting, and evaluating operations to suppress the formation of hail. Hail is the product of vigorous, deep convection in the atmosphere. The most common approaches to hail suppression involve seeding a storm with nucleating agents using airborne, ground-based, or rocket and artillery delivery systems....
