  • USACE to hold public meetings for Draft Master Plan for Harry S. Truman Lake

    A draft Master Plan for Harry S. Truman Dam and Reservoir, with an Environmental Assessment and a Finding of No Significant Impact, has been prepared by the Kansas City District, U.S. Army Corps of Engineers and is ready for public review. These documents were prepared in accordance with the National Environmental Policy Act and existing USACE policy and regulations. The Master Plan is the strategic land use management document that guides the comprehensive management and development of all projects, recreational, natural and cultural resources throughout the life of the project. The Master Plan guides efficient and cost-effective management, development and use of project lands. It is a vital tool for the responsible stewardship and sustainability of project resources for the benefit of present and future generations.

  • Making a difference, one project at a time

    The U.S. Army Corps of Engineers utilizes volunteers as a workforce multiplier across the nation which resulted in an equivalent value of more than $45 million in volunteer hours last year. Volunteers are filling roles at lakes across the nation. More than 2,100 volunteers assisted the Fort Worth District in 2022. Thanks to the volunteers, many of the lakes were able to complete projects that would have otherwise been delayed.

  • Drastic difference between air and water temperature could kill

    With the onset of record-breaking heat across much of the Pacific Northwest, it’s imperative that people wear life jackets while swimming, boating and fishing. While air temperatures may be high, water temperatures can be much lower and can be deadly, according to water safety statistics.

  • Dynamic Material Properties of Grade 50 Steel: Effects of High Strain Rates on ASTM A992 and A572 Grade 50 Steels

    Abstract: Uniaxial tensile tests were conducted on American Society for Testing Materials International (ASTM) A992 and A572 Grade 50 steels at increasing strain rates to determine the material strength properties of structural members subjected to dynamic loadings. The increase in dynamic yield strength and ultimate tensile strength was determined to update design criteria within UFC 3-340-02, which are currently limited to ASTM A36 and A514 steels. The proposed updates will provide the necessary information required to design blast-resistant structures utilizing modern-day structural steels. The dynamic material properties determined by high-rate tensile tests were compared to static values obtained from ASTM E8 standard tensile tests. The comparisons were used to calculate dynamic increase factors (DIFs) for each steel at strain rates from 2E-3 to 2E0 inch/inch/second. The experiments revealed that the A992 steel exhibited an increase in yield strength up to 45% and ultimate tensile strength up to 20% as strain rate increased over the range tested. The A572-50 steel exhibited a similar increase in yield strength up to 35% and ultimate tensile strength up to 20%. The DIF design curves developed during this research will allow engineers to more efficiently design structural steel components of hardened structures for the protection of our nation’s critical infrastructure.
