Filed Tests and Analytical Studies of the Dynamic Behaviour and the Onset of Galloping in Traffic Signal Structures

1.

2007 ... Michael J. Floreah, Lance Manuel, Karl H. Frank and Sharon L. Wood Unpredictable fatigue failures of cantilevered traffic signal structures in Texas and throughout the United States in recent years have created the need to study their fatigue behavior. Based on recent research, the American Association of State Highway and

Field Testing of Cantilevered Traffic Signal Structures Under Truck-Induced Gust Loads

2.

2007 ... Matthew N. Albert, Lance Manuel, Karl H. Frank and Sharon L. Wood Changes in the AASHTO fatigue design equations for truck-induced gust loads have been made in recent years. However, there has not been any long-term field testing of cantilevered traffic signal structures to verify the design equations. In this study, two

Revision of AASHTO Fatigue Design Loadings for Signs, Luminaires, and Traffic Signal Structures, for Use in Texas

3.

2007 ... RS: Chris W. Letchford; Researchers: Andrew Budek [and four others] New provisions for fatigue design in Section 11 of the Standard Specifications for Structural Supports for Highway Signs, Luminaires and Traffic Signals issued in 2001 have made it difficult to find economical AASHTO-compliant design solutions for

Software for Computing Annual Frequency of Collapse for a Bridge

4.

2006 ... Lance Manuel VIOB (Vessel Impact on Bridges) is a software that was developed in order to make possible the large number of calculations necessary to estimate the return period associated with collapse of a bridge spanning a waterway. Making use of the assembled database on vessel traffic, the waterways, and the

A Probabilistic Analysis of the Frequency of Bridge Collapses due to Vessel Impact

5.

2006 ... Lance Manuel [and six others] The collapse of the Queen Isabella Causeway in 2001, caused by a vessel collision, sent an alarming message to the state of Texas that vessel impact on bridges is a serious issue and that the possibility of such accidents needs to be considered in the design and evaluation of any bridge spanning a

Vessel Impact on Bridges

6.

2005 ... RS: Lance Manuel; Researchers: Loukas F. Kallivokas and Eric B. Williamson The collapse of the Queen Isabella Causeway Bridge resulting from a vessel collision motivated this study that recognizes that vessel impact on bridge is a serious issue and that the likelihood of such accidents needs to be carefully evaluated in the design

Development of a new methodology for characterizing pavement structural condition for network-level applications

8.

2003 ... Zhanmin Zhang [and three others] Huge quantities of bituminous mix in the form of seal coats and HMAC thin overlays are applied by the TxDOT every year to improve ride quality and seal existing cracks, but these measures do not correct possible underlying weakneses that will cause roughness or distress to quickly

Optimal Inspection of Fracture-Critical Steel Trapezoidal Girders

9.

2003 ... Hsin-Yang Chung, Lance Manuel and Karl H. Frank A reliability-based procedure for inspection scheduling of steel bridges is proposed to yield the optimal (most economical) inspection strategy that meets an acceptable safety level through the planned service life. Two fatigue reliability formulations that can be applied
