Rockscience has been busy soliciting feedback from their user base on news features for their settlement analysis software program, Settle3D. After receiving all of the feedback in the beta program, many of the user suggestions have been implemented by Rockscience in the Version 3.0 release of Settle3D. Some of these improvements include the ability to model non-horizontal soil layers, user interface improvements, new options for defining water level, enhanced graphing capabilities, and 64-bit parallel processing.

New Solution Saves Money and Time Preventing Loss of Grain and Equipment Damage
MOUNT AIRY, NC—Soil consolidation and settlement happens. It’s a fact of farm life. Secondary consolidation slowly forces water out of the spaces between soil particles. As this happens, soil particles move close together and settling occurs. Floors drop and become uneven. Newer grain silos and bins are using concrete floors instead of metal, and as secondary consolidation occurs beneath them, depressed or “settled” areas, form within the bin. Grain accumulates in the depressed areas, but cannot be retrieved by the bin sweeper. In fact, the sweeper, a kind of auger that transports grain up from the floor, can become damaged from prolonged exposure to the uneven floor.
This is exactly what Kirk Roberts of CJGeo, a Williamsburg, Virginia-based commercial foundation repair and geotechnical contractor, found when he got the job to repair the foundation of a massive 106-foot diameter grain bin at a poultry processing facility on the Eastern Shore of Maryland. “Once they removed the hundreds of thousands of bushels of grain, we found the floor had dropped some three inches in one section of the bin leaving a large pocket of grain out of reach of the bin sweeper.”

New FHWA Manual on Spread Footings for Highway Structures
Hot on the heals of the revised MSE Wall Manual, the FHWA has released another manual, this one on Spread Footings. Selection of Spread Footings on Soils to Support Highway Bridge Structures was authored by Naresh C. Samtani, PE, PhD, Edward A Nowatzki, PE, PhD and Dennis R. Mertz, PE, PhD. So what is this manual all about? I think the foreword by Scott Anderson, PE, PhD of the FHWA Resource Center says it best:
