This book was released on 1998 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The research study consisted of Phase II of the development and full-scale vehicle crash testing of a bullnose barrier concept for the treatment of median hazards. The bullnose guardrail consisted of a 12-gauge thrie beam rail supported by twenty-two wood posts, eleven posts on each side of the system. Horizontal slots were cut in the valleys of selected thrie beam sections to aid in vehicle capture as well as to reduce the buckling and bending capacities of the rail. Two full-scale crash tests were performed, both using a 2000-kg pickup truck. The first crash test, impacting at a speed of 100.2 km/h and an angle of 0 degrees, was unsuccessful following the rupture of the thrie beam and subsequent uncontrolled penetration of the vehicle behind the barrier. Computer simulation of the failed test was performed using LS-DYNA. Analysis of the simulation and full-scale test results led to the addition of two steel cables placed behind the top and middle humps of the thrie beam nose section to aid in truck containment without stiffening the barrier. Computer simulation of the modified design demonstrated successful containment of the pickup truck. The second test, impacting at a speed of 103.5 km/h and an angle of 0 degrees was determined to be successful according to the safety standards set forth by the Test Level 3 (TL-3) evaluation criteria described in the NCHRP Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features" (1993). The next phase of the bullnose barrier system design will be to complete the remaining crash tests needed for compliance with the NCHRP Report No. 350 safety standards for median barriers.

Available in PDF, EPUB and Kindle. Book excerpt: The research study consisted of the design, fabrication, and full-scale vehicle crash testing of a bullnose barrier concept for the end treatment of median hazards. The bullnose concept consisted of a 12-gauge thrie beam rail supported by twenty-two wood posts, eleven posts on each side of the system. Horizontal slots were cut in the valleys of selected thrie beam sections to aid in vehicle capture as well as to reduce the buckling and bending capacities of the rail. Two full-scale crash tests were performed, the first using a 2000-kg pickup truck and the second using an 820-kg small car. The first test, impacting at a speed of 101.4 km/h and an angle of 0.1 degrees at a 1/4-point offset, was unsuccessful. Although the vehicle showed no potential for vehicle override, the thrie beam ruptured causing uncontrolled penetration of the vehicle behind the barrier. Consequently, the bullnose system was modified to include additional breakaway posts and horizontal slots in other thrie beam sections. The second test, impacting at a speed of 103.3 km/h and an angle of 3.4 degrees was determined to be successful according to the safety standards set forth by the Test Level 3 evaluation criteria described in the National Cooperative Highway Research Program (NCHRP) Report No. 350, "Recommended Procedures for the Safety Performance Evaluation of Highway Features". The data and information gathered from the development phase of this project will be used in the development of a computer simulation LS-DYNA model of the bullnose system as well as an improved bullnose guardrail design

Available in PDF, EPUB and Kindle. Book excerpt: This research study consisted of the development and testing of a short-radius guardrail system for protection of hazards near intersecting roadways and capable of meeting the Test Level 3 (TL-3) impact conditions of the NCHRP Report No. 350 criteria. A short-radius system was designed and consisted of a curved and slotted thrie beam nose section with two adjacent slotted thrie beam sections supported by breakaway posts. One side of the system was attached to a TL-3 steel post transition while the other was attached to a TL-2 end terminal. A series of four full-scale crash tests were conducted on the short-radius guardrail system.

Download or read book Hard Times and New Deal in Kentucky written by George T. Blakey and published by University Press of Kentucky. This book was released on 2014-07-15 with total page 271 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Great Depression and the New Deal touched the lives of almost every Kentuckian during the 1930s. Fifty years later the Commonwealth is still affected by the legacies of that era and the policies of the Roosevelt administration. George T. Blakey has written the first full study of this turbulent decade in Kentucky, and he offers a fresh perspective on the New Deal programs by viewing them from the local and state level rather than from Washington. Thousands of Kentuckians worked for New Deal programs such as the Civilian Conservation Corps and the Works Projects Administration; thousands more kept their homes through loans from the Home Owners Loan Corporation. Tobacco growers adopted new production techniques and rural farms received their first electricity because of the Agricultural Adjustment and Rural Electrification administrations. The New Deal stretched from the Harlan County coal mines to a TVA dam near Paducah, and it encompassed subjects as small as Social Security pension checks and as large as revived Bourbon distilleries. The impact of these phenomena on Kentucky was both beneficial and disruptive, temporary and enduring. Blakey analyzes the economic effects of this unprecedented and massive government spending to end the depression. He also discusses the political arena in which Governors Laffoon, Chandler, and Johnson had to wrestle with new federal rules. And he highlights social changes the New Deal brought to the Commonwealth: accelerated urbanization, enlightened land use, a lessening of state power and individualism, and a greater awareness of Kentucky history. Hard Times and New Deal weaves together private memories of older Kentuckians and public statements of contemporary politicians; it includes legislative debates and newspaper accounts, government statistics and personal reminiscences. The result is a balanced and fresh look at the patchwork of emergency and reform activities which many people loved, many others hated, but no one could ignore.
