Prediction of Structural Response to Large Earthquakes by Using Recordings From Smaller Earthquakes
The feasibility of predicting structural response to large earthquakes by using recorded responses from collocated smaller earthquakes is investigated. Records from large earthquakes can...
Design of Half-Through or Pony Truss Bridges Using Square or Rectangular Hollow Structural Sections
The initial part of this paper will outline some of the research, testing, and investigation which has been done on half-through truss bridges. This research is primarily concerned with...
Seismic Performance and Retrofit of the Golden Gate Bridge
Since its opening in 1937, the Golden Gate Bridge has endured and functions as an important transportation link for Bay Area commerce and commuters. After an earthquake in 1989, T.Y. Lin...
Innovations in Major Suspension Bridge Design
Before the Tacoma disaster, the trend in bridge-building is on increasing slenderness. But since its occurrence, a high degree of aerodynamic stability is required. Presented are designs...
Akashi-Kaikyo Bridge Underconstruction
This paper presents 1) brief history of the survey work, 2) brief description of the physical dimensions and structural system, 3) major studies for the design, 4) development of higher...
Generalized Optimal Active Control with Embedded and Half-space Soil-Structure Interaction
The paper presents an optimal active control algorithm with soil-structure interaction for seismic response. By using an intelligent device in the feedback gain matrix, the algorithm can...
Modal Filter Based Structural Control of a Highway Bridge
An Adaptive Modal Filter (AMF) algorithm is developed which uncouples complicated multi-mode structural dynamic response into simple single-mode response. The application to active structural...
California Airports: Ground Access Vehicle Trips, Emissions and Emission Reduction Strategies
The following paper discusses the volume of trips and emissions associated with ground access vehicles to an d from California airports, and potential ways to reduce these emissions. this...
Rail Service to Airports
Rail service is available at seven North American airports, and service is available by a shuttle bus connection at more than nine other North American airports. Additionally, rail service...
Optimal Supply of Parking at Airports
The design capacity of parking facilities at airports is generally estimated in relation to one or more standard decision variable such as enplaning passengers, number of employees, and...
Operational Interactive Hydrologic Forecasting with the National Weather Service River Forecast System
The National Weather Service River Forecast System (NWSRFS) consists of several major hydrometeorologic subcomponents to model the physics of the flow of water through the hydrologic cycle....
Exploring Management Alternatives with Interactive Simulation
A drought exercise was held to disseminate information about a proposed change in reservoir management. In the drought exercise, an interactive operations model was used to simulate drought...
Simulating Water Supply Systems of the Raritan Basin
A recently developed interactive river-aquifer system model (IRAS) was used to study the Raritan River Basin as part of the effort to revise the New Jersey Statewide Water Supply Master...
Rehabbing Bridges Under Traffic
Four urban examples demonstrate how an owner's decision to keep it open during rehabilitation construction forces the designers to contend with an extra set of problems. Reanchoring...
Success Syndrome: The Collapse of the Dee Bridge
Scaling up existing successful designs can cause latent weaknesses to become dominant, leading to catastrophe. By studying past failures where this has happened--for example, the 1847...
Road to Recovery
The effect of the Loma Prieta earthquake on San Francisco's elevated viaduct system is still being felt more than four years later. Immediately after the quake, the entire...
Recommendations for Standards in Hydraulics
Prepared by the Task Committee on Recommendations for Standards in Hydraulics of the Hydraulics Division of ASCE. This report investigates whether...
Modular Evolution
The construction industry typically thinks of modular steel bridges in terms of the World War II vintage Bailey Bridge. The Bailey Bridge was designed to be quickly deployed to replace...
A League of Their Own
New baseball stadiums in Cleveland and Arlington, Tex., opening in April 1994, combine the nostalgia of traditional ballparks with state-of-the-art site planning and structural engineering....
Lightweight Concrete for a Segmental Bridge
Structural lightweight concrete can help increase the stiffness and decrease the mass of a bridge; both are qualities that make the structure more likely to survive an earthquake. Ordinarily,...
