ASCE/SEI’s 7-16 publication, Minimum Design Loads and Associated Criteria for Buildings and Other Structures, was published last year and contains some new seismic design standards. According to an analysis by one group of industry professionals […]
The 645-foot tall Millennium Tower in San Francisco settled an incredible 16 inches, and tilted at least 2 inches to the northwest. Recently the City and County Department of Building Inspection (DBI) issued interim guidelines […]
The Louisiana Transportation Research Center has released a report that presents the reliability-based analyses for the calibration of the resistance factor for load and resistance factor design of axially loaded drilled shafts. Here is the […]
Here is a collection of new, revised and updated ASTM standards from October 2012 that may be of interest to geoprofessionals. See the list after the break…
FEMA has recently released a new document titled “Summary of Existing Guidelines for Hydrologic Safety of Dams”. I was pleased to hear about this report from one of it’s co-authors, Amanda Hess of Gannett Fleming. […]
I’ve collected a list of new, updated and otherwise updated ASTM standards that pertain to geotechnical engineering, construction and materials testing and laboratory testing of soil, rock, geosynthetics and related fields. This month’s updates contains a new standard for measuring hydraulic conductivity of recycled tire-derived aggregate, updates to leak detection standards and more. Click through for the list of updates to ASTM standards you can’t afford to ignore in your practice.
This post contains a list of new, revised and otherwise updated ASTM standards that pertain to the geotechnical engineering, materials testing and related fields. The standards for the standard proctor and modified proctor tests have been revised. There are a number of updated standards associated with cements and mortars, and curiously several standards that have been withdrawn with no replacements, including the standard for testing collapse susceptibility of soils, one pertaining to curing of concrete, and two for testing of soil-cement mixtures. Click through to see the updates to the ASTM standards.
Geotechnical engineers, geotechnical lab managers, CQA service managers and others utilize ASTM standards on a daily basis. Here at GeoPrac.net, we monitor the periodic updates from ASTM and summarize changes to relevant standards that may be of interest to geoprofessionals. Click through for a list of revised and reapproved standards from May of 2012.
Here is a collection of new, revised and updated ASTM standards from April 2012 that may be of interest to geoprofessionals. See the list after the break…
This post contains a list of new, revised and otherwise updated ASTM standards that pertain to the geotechnical engineering, materials testing and related fields. Standard C39/C39M for testing the compressive strength of concrete cyllinders was updated, as was C42/42m for obtaining and testing drilled cores and sawed beams of concrete. The month of March also saw several geosynthetic standards being updated or added, including new standards for selecting the test method for geomembrane seams, and for testing the flexural rigidity of geogrids and other geosynthetics. There are also a few updated standards related to asphalt mix design and sampling of asphalt. Click through for updated ASTM Standards relating to geoprofessionals.
