Shake-table results aimed at codifying a rational design methodology for precast concrete parking structures

The Precast/Prestressed Concrete Institute (PCI) has completed tests of a large-scale, three-story precast concrete parking structure and has begun using the results to create standards that can be incorporated into building-code requirements. The tests, completed in August at the Network for Earthquake Engineering Simulation (NEES)/Englekirk Structural Engineering Center in San Diego, Calif., are part of the final year’s work on a 5-year, $2-million-plus research program to improve industry standards for the design and construction of diaphragms used with precast, prestressed concrete components.

EPA proposes construction site regulations

The U.S. Environmental Protection Agency is seeking comments on its proposed guidelines to control the discharge of pollutants from construction sites. The proposal would require all construction sites to implement erosion and sediment control best management practices to reduce pollutants in stormwater discharges. In addition, for certain large sites located in areas of the country with high rainfall intensity and soils with a high clay content, stormwater discharges from a construction site would be required to meet a numeric limit on the allowable level of turbidity.

New ISO standard for safe, long-lasting buildings and structures

ISO has published a new standard to help engineers, builders, and regulators to design structures that are safe and resistant to failure due to environmental and mechanical stresses, and to material degradation.

ACI releases 530-08 for masonry structures

The American Concrete Institute released one of its best-selling publications, 530-08: Building Code Requirements and Specification for Masonry Structures and Related Commentaries.

Quake research to provide rate glimpse of how structures collapse

Structural engineers at the University at Buffalo are conducting some of the most comprehensive experiments ever attempted to develop methods of evaluating and designing steel buildings so that they will be less vulnerable to collapse during strong earthquakes.

Associations to develop LRFD pre-standard for composite structures

ASCE and ACMA signed a three-year agreement to develop a pre-standard for Load and Resistance Factor Design for Pultruded Fiber Reinforced Polymer Composite Structures.

History of highway structures

The Transportation Research Board Structures Section recently published Transportation Research Circular E-C104: Fifty Years of Interstate Structures-Past, Present, and Future. The circular documents some of the key legislation, specifications development, and advances in research, design, and construction for bridges and other highway structures since the signing of the Federal Highway Act of 1956.
