Earthquake Barrier Technology: Sliding-Friction Energy Dissipation
The first project in America to use friction damping was approved by the City of Los Angeles for the retrofit of a 10-story concrete frame building, designed to resist a Maximum Credible...
Uplift Resistance of Plywood and OSB Roof Sheathing
A test program to determine the resistance of plywood and OSB roof sheathing to uplift pressures created by wind flowing over a residential roof structure will provide valuable data to...
AISI-FHWA Model Bridge Test
The Model Bridge Study involved a large experimental test program to evaluate the behavior of a 0.4-scale model of a two-span continuous plate-girder bridge with modular precast prestressed...
Horizontally Curved Steel Bridge Research-Update 2
Theory and data necessary for the development and calibration of an LRFD based curved steel bridge specification do not presently exist. To address these needs, the Federal Highway Administration...
Current and Future Research in Steel Bridge Structures
The topics I have listed are ones which I am aware through discussions with various researches, designers, and industry representatives. The list of topics is presented as a starting point...
Pre-Engineered Short Span Steel Bridges
The American Iron and Steel Institute has developed a package to aid in expediting the design of short-span steel bridges for use by owners, designers, fabricators, and contractors in...
Condition Assessment of Highway Bridges
An application of modal testing and structural identification in the condition assessment of bridges is presented. Damage definition and conceptualization is discussed. Damage detection...
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...
Design of Frames Using Notional Horizontal Force
The cantilever columns and portal frames are studied by using the notional horizontal force design concept. This concept intends to eliminate K-factor in the frame design. It was found...
Design Implications of Advanced Analysis in LRFD
This paper discusses two advanced analysis methods, and their use in LRFD format. The first approach is called the notional load plastic hinge method and the second is called the second-order...
Behavior of Tall Frame Combining Rigid and Semi-Rigid Connections
In this paper, the applicability of the mixed use of rigid and semi-rigid connections in the tall frame is discussed. It is tried. for 4-bay 8-storey frame to be numerically analyzed for...
Seismic Study of a Cable-Stayed Bridge
The focus of this paper is to investigate the non-linear and linear behavior of a cable-stayed bridge in a seismic environment. Three design features of a cable-stayed bridge are studied:...
Seismic Issues in Structural Engineering Codes and Practice
It is necessary that we view the seismic events in an overall probabilistic mode and determine the criteria for acceptable damage at various levels of service in the building. We need...
Aesthetic Considerations in the Design of a Stack Extension
The Connecticut D.E.P. mandated increase in height of the boiler stack at Backus Hospital in Norwich, CT presented many problems. Adding a new 45 foot vertical section atop the old brick...
Civil Engineering and Civic Monuments: The Commissioning, Design and Public Perception of Urban Infrastructure Projects
This paper analyzes the roles that some infrastructure projects play as civic monuments and public places, and how these functions interact with their technical performance and utility....
Bridging the Gap Between Architecture and Engineering
Building design is interdisciplinary by nature. Indeed, the collaboration of architect and structural engineer is critical to the success of building design projects. Yet with few exceptions...
Aesthetic Issues in Timber Bridges
The vocabulary of visual design and several generally accepted major principles of visual design are reviewed in order to provide a 'context' for case studies of award-winning timber bridges....
Implementation of Passive Energy Dissipation Systems in the United States
Significant advances in the field of passive energy dissipation for improved structural seismic resistance have been made in recent years. Developments in research and analysis techniques...
Utilizing Visco-Elastic Dampers in the Seismic Retrofit of a Thirteen Story Steel Framed Building
A 13 story steel framed building in Santa Clara Country, California exhibited strong beating effects (torsional coupling) and prolonged building response as result of various seismic events....
