The SoFi Stadium Perimeter Wall: A Retaining Wall Helps Avoid Encroaching on LAX Airspace
SoFi Stadium, one of the two newest venues in the National Football League, opened in September 2020 after breaking ground in November 2016. The stadium hosts NFL games for the Rams and Chargers, and will...

Design of Submarine Pipelines Against Upheaval Buckling
This paper describes part of a comprehensive joint-industry project on upheaval buckling. It develops a semi-empirical simplified design method and detailed design methods based on a new numerical analysis,...

Pipe Characteristics
Microtunneling pipe should meet the following general requirements: Circular shape with a flush outside surface (including at the joints); Strength sufficient to withstand both the installation...

Pipe Design
The pipes and joints, once installed, must be capable of safely withstanding, for the project design life, all in-use service loads, including those associated with the following factors:...

Design and Installation of Auger Steel Catenary Risers
The Auger export pipelines are connected to the TLP by steel catenary risers (SCRs). This is believed to be the first time steel pipe has been used for catenary risers. SCRs offer advantages...

From Competitors to Partners
Embracing a competitor as a business partner may be somewhat uncomfortable for small engineering firms�at least initially. There is natural concern about what a fellow team member�who...

The Effect of the Slab on Beam-Column Joint Behavior
The three-dimensional effect of slab interaction on frame behavior has been observed in lateral load tests on beam-column-slab elements....

Pipe Up
The East Bay Municipal Utility District (EBMUD) provides potable water for approximately 1.2 million people in San Francisco's East Bay area and is constructing seismic upgrades...

Cable Access
By moving the expansion joints off the main, cable-stayed span and creating innovative cable connections and tower configurations, Parsons Brinckerhoff Quade & Douglas Inc. (PB)...

Corrosion Control
As pipe systems with nonwelded joints have become more common, so have problems with corrosion. It's up to designers to carefully consider corrosion issues in order to avoid...

Risk Analysis of Joint Reservoir Operation in Central Taiwan
Risk analysis for shortage of water on the joint operation of Li-Yu-Tan Reservoir and Shih-Kang Dam (Reservoir) in central Taiwan is presented in this paper. Deter ministic simulation,...

Piggyback Tunnels
Coincidental alignments of the Central Artery Tunnel and the Transitway subway line under the streets of Dewey Square in Boston presented the sponsoring agencies with a rare opportunity...

Documenting Design-Build
For engineers more familiar with the traditional design�bid�build process, design�build might present some unforeseen risks and responsibilities. To define and allocate these, the Engineers...

Enabler Chassis Features and Mobiltiy Analysis
The Enabler is a proposed Lunar Base work vehicle. The unique construction of the Enabler's six-wheeled chassis provides unusual articulation for steering, balancing, and overcoming obstacles....

The Optimal Selection of Robot Modules for Space Manipulators
Monolithic robot systems are poorly suited to the broad requirements and uncertainties of space automation applications. Designers have considered building many robots, each of which can...

Effects of Force Reflection on Telerobotic Performance
The University of Kansas Augmented Telerobotics Laboratory conducted a study to examine the effects of force reflection on telerobotic system and operator performance in performing two...

A Conceptual Study of A Solar Power Satellite Using Centrifugal Force
We studied the self deployable Solar Power Satellite (SPS) using centrifugal force in order to explore ways in reducing construction costs. We designed a 340 kW SPS, and studied the unfolding...

Validation of the European Yield Model for Nailed Connections
Recent changes in National Design Specification for Wood Construction (NDS) connection design methods make it necessary to validate the European yield model (EYM) for nails. Test values...

Cyclic Behavior of Joints Between Steel Beams and Reinforced Concrete Columns
The design and behavior of composite beam-column joints for seismic design are reviewed based on the results of tests. Issues addressed include the strength, deformation, and toughness...

Recent Studies of the Behaviour of Semi-Rigid Composite Connections
Following renewed interest in the semi-rigid properties of joints in steel frame structures, a more recently identified area of research has been the study of composite connections. The...
