3-D Dynamic Analysis of the Brent-Spence Through-Truss Bridge
A three dimensional finite element model is developed for the free vibration analysis of main bridge. The model was calibrated by comparing the free vibration analysis results with ambient...

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...

Rigid Beam-To-Column Connection Detail for Circular Composite Columns
Steel pipes with relatively thin wall thickness and filled with high strength concrete have been used in building construction. Some of the advantages of this type of column include eliminating...

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...

Towards Robust, Effective and Efficient Second Order Analysis of Practical Steel Frames
The performance of the widely used finite element and the stability function methods and the recently developed pointwise equilibrating element in second order nonlinear analysis of framed...

A Nonlinear-Analysis-Based Procedure for Evaluating Load-Carrying Capacity of In-Plane Steel Frames
A simple method based on geometrically nonlinear analysis is proposed to evaluate the load-carrying capacity of a steel structure. The effects of material nonlinearity and residual stress...

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 Analysis of Failure and Loss of Function of Water Pumping Facilities
Water company managers evaluating potential seismic damage effects on a pumping facility will require a reasonable estimate of the probable magnitude earthquake that has potential to disrupt...

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...

Response Study of a Flexible Building Using Three Earthquake Records
This paper examines the response of a flexible building during three earthquakes. The records from the building are long and contain low frequencies. The site frequency (0.33-0.38 Hz)...

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....

Testing of Concrete Curtain Wall Panels Reinforced with FRP Grids
The objective of this paper is to evaluate the suitability of Fiber Reinforced Plastic (FRP) grids for use as a structural; reinforcement in concrete curtain wall panels. This paper describes...

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....

Seismic Upgrades Using Energy Dissipation Devices
This paper presents a model for developing comparative seismic rehabilitation schemes for essential facilities using both conventional techniques and passive control devices. Essential...
