Download or read book Fatigue Testing of Stiffened Traffic Signal Structures written by John P. Peiffer and published by ProQuest. This book was released on 2009 with total page 149 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sixteen fatigue tests were performed on twelve cantilevered traffic signal poles to quantify the fatigue resistance of a ring-stiffened built-up box connection. Two poles sizes were tested in three configurations: in-plane, out-of-plane, and diagonal. Cyclic loading was applied to produce stress ranges of up to 16 ksi in the main member, more than six times the stress range observed during field testing. Performance test results for this connection typically plot above an AASHTO detail design stress category D. Connection bolt fatigue failures were observed and may be the limiting fatigue design feature.
Download or read book Fatigue Performance of Variable Message Sign Luminaire Support Structures Fatigue related wind loads on highway support structures written by Gary R. Consolazio and published by . This book was released on 1998 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report describes research which focused on determining equivalent static pressures for fatigue loads on cantilevered highway sign support structures. A cantilevered variable message sign (VMS) instrumented with strain gages, pressure transducers, and a wind sentry, was continuously monitored for three months. Short-term testing was conducted on the structure in order to determine the dynamic characteristics such as stiffness, natural frequency, and percent of critical damping. Long-term monitoring was performed to capture the structure's response to natural wind gusts, galloping, and truck-induced wind gusts.

This book was released on 1998 with total page 106 pages. 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
