Howdy, Partner
Litigation has long been a nemesis to the construction industry. In recent years, contractors and owners have used innovative alternative dispute resolution (ADR) techniques, such as arbitration,...

Safeguarding Steel
U.S. bridges are caught in the money squeeze. Painting has become a luxury few public agencies can afford and complying with EPA regulations has escalated costs even more. The paint/coatings...

Piles Over Problems Sites
It's increasingly difficult to find suitable space for construction in urban areas. Pile foundations can fill the void by making questionable and heavily regulated sites,...

Life in the Fast Track
Through innovative financing and skillful construction management, Oklahoma is proving that transportation megaprojects are still possible, even during an economic downturn. The result...

Project Management: Keys to Success
Successful construction projects can be traced to several key factors observed by the owner, the AE and the contractor. They include: 1) Goals and commitment of the managing partners agreed...

Double Diamonds: New Brand for a Texas Bridge
Double diamond towers, distinctive as a cattle brand but tall as a 44 story building, have reached landmark status on the Texas Gulf Coast even though the bridge they will carry won't...

Automating The Corps
Automated soil testing machines solved several problems at once for the U.S. Army Corps of Engineers' South Western Division Laboratory in Dallas, Texas. The machines replaced...

Bayesian Reliability Updating of Existing Steel Girder Bridges
Bayesian statistics is used to update the reliability of existing composite steel girder bridges. A 60 ft. long simply supported superstructure is considered. The reliability for the ultimate...

On the Role of Experimental Mechanics in Assessing the Performance of Concrete
The role of experimental mechanics in material characterization, design, construction, performance evaluation, repair, rehabilitation and finally destruction of concrete structures is...

Behaviour of Prestressed Concrete End Blocks
This paper briefly reports on a series of experiments carried out on strip-loaded prestressed concrete end blocks. The results show that corresponding design methods presently used in...

Experimental Photoelastic Analysis of Tunnels Containing Cracks
Due to the presence of cracks the strength of the structure is decreased in the present paper an experimental two dimensional photoelastic technique has been developed to analyze the circular...

Anatomy of the Loma Prieta Earthquake Records of Two Steel Buildings Using MIMO System Identification
The Loma Prieta strong-motion records of a 4-story and a 47-story steel building are analyzed using system identification. A time variation study from the 4-story building records reveals...

Scattering of Waves by Steel Reinforcement in Concrete
The application of wave-sensing methods to the non-destructive evaluation of concrete structures requires often the use of simple (or at least tractable) models for the solution of the...

Stability of Beams in Eccentrically Braced Frames
As the link yields and strain hardens in an eccentrically braced frame, the beam segment-outside of the link is subject to a combination of high axial force and bending moment. For certain...

Locally Buckled Plastic Hinge Behavior Under Monotonic and Cyclic Loading Condition
In order to clarify the influences of local buckling under monotonic and cyclic loading conditions, experimental studies were carried out on W8x10 A-36 structural steel members subjected...

Design Codes for Lunar Structures
The American Institute of Steel Construction (AISC) Manual of Steel Construction is a codification for the design and construction of steel structures. It includes information, some tabular...

Genesis: The Creation of a Lunar Base
A lunar basing scenario that utilizes lunar resources to manufacture lunar concrete modules is considered. An eleven year basing program, starting with initial robotic exploration and...

Lunar Oasis
The Lunar Oasis emphasizes development toward self-sufficiency in order to reduce dependence on the Earth for resupply and to enable expansion utilizing indigenous resources. The Oasis...

Building a Space Infrastructure: The Reclamation Experience
The third and last duty of the ... commonwealth is that of erecting and maintaining those public institutions and those public works, which, although they may be in the highest degree...

Construction and Development of a Human Base on Mars
Humans on Mars will face many challenges. Possibly the first and one of the longest will be the construction and growth of the base. In this paper a number of techniques are looked at...
