"ENGINEERING AND CONSTRUCTION HISTORY OF THE ASTRODOME AND THE OUTSTANDING CAREER OF RICHARD P. DOSS, HARRIS COUNTY ENGINEER" 

Just about the time Richard Doss had taken over as County Engineer in 1961, the Harris County Domed Stadium’s 1/8 scale model was being tested in a wind tunnel in McDonnel Aircraft Corporation facility in St. Louis, Missouri. This was just the start of the project that was to be known as the Astrodome. Construction documents for this unique project were issued in October 1962 and were completed in November 1964, six months ahead of schedule.  Conceived as the home of the Houston Colts and the Houston Oilers, it was termed by many as the Eighth Wonder of the World.  It was the first time that a stadium was built for both baseball and football that was totally enclosed and fully air-conditioned. Circular in shape, the outer diameter of the Astrodome is 710 feet, and the clear span of the lamella dome roof is 642 feet. The presentation will provide an overview of the different structural challenges that faced the design team in the nineteen sixties. This facility served the Houston Oilers until 1996 and the Houston Astros until 1999.

TECHNICAL SPEAKERS 

Tech Session 1: "Data Driven Approach Towards Concept Development – A Traffic Engineer’s Perspective”

The focus of this presentation is to provide an overview of the tools and techniques that traffic engineers should consider within the realm of a multi-disciplinary approach towards identifying, developing and evaluating transportation concepts to address mobility and safety needs of the travelling public. With the focus on performance measures based planning how can we use the modeling tools to reasonably capture measures of effectiveness as part of alternatives evaluation.

Tech Session 2:  “Stability Analysis of the USS Salem Wharf Under Gravity Loads”

The USS Salem Wharf Structure is located in Quincy, MA and was built in 1959 to expand a regional ship building yard.  It has been re-purposed and currently surves to moor the USS Salem, a decommissioned US Navy heavy cruiser and floating museum.  In its current use, the wharf is subjected to substantially smaller gravity loads than it was initially designed to support.  Recent inspections of the over 700 ft. long structure revealed significantly but highly localized corrosion in many of the supporting steel piles.  In the most severe cases the corrosion approached nearly complete loss of the pile cross section.  The lack of specific guidelines for calculating the capacity of such severely corroded piles made the reliable assessment of the remaining capacity of the structure challenging.  Preliminary (overly conservative) calculations suggested that the structure could not support its own self-weight, although it was still standing.  This was believed to be due to several factors that are not considered in the simplified preliminary calculations including: the relatively high post-buckling capacity of hte steel piles and the high stiffness of the superstructure which permitted load redistribution from buckling piles to adjacent piles.  To more fully understand the response of the wharf to gravity loads, a detailed finite element analysis was conducted.  The finite element model was also used to conduct a parametric study of the wharf to investigate the influence of key parameters on the stability of the structure.  This detailed analysis was made possible due to the availability of detailed information regarding the geometry of the corroded piles which was obtained from an extensive underwater investigation.  The analysis results suggest that in addition to its self-weight, the structure could support a uniformly distributed load of up to 185 psf, even if the superstructure was assumed to be heavily cracked.  The findings highlight the importance and value of detailed structural inspections and advanced analysis techniques in characterizing the performance of existing structures.
