Use of Composite Timber-concrete Floors in Residential Buildings
Timber-concrete floors are widely used in the Gulf region for its resistance to hot and aggressive environment of the area. However, due to the fact that no shear connector is provided,...
Numerical Simulation of Site Effects
Numerical simulations have proved to be very powerful tool in the analysis and study of site effects. Numerical models may be used (i) to study the pattern of shaking during a particular...
Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...
Research and Development ? Why bother?
As the world becomes a true global marketplace, the ramifications of this change is felt in all aspects of business. Products and services from around the world are beginning to appear...
Modelling of Extended Endplate Bolted Connections
A methodology based on finite element modelling is examined to study the behaviour of extended endplate bolted connections. ANSYS (Rev. 4.4), a large scale finite element program is used...
ATLSS Connections with Moment Capacity
ATLSS Connections are a family of beam-to-column connections which utilize the self-aligning feature of a specially designed connector and are developed for possible use in an automated...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
High Strength Shotcrete and Concrete on the SSC Project
This paper addresses the technical aspects related to the use of high strength shotcrete and concrete on the Superconducting Super Collider (SSC) project. 7,000 psi shotcrete and 8,000...
Structural Analysis of Pavements: State-of-the-Art
This paper presents the state of the art of the structural analysis of pavements, using high-speed computers. The numerical models include layered analysis and finite-element and finite-difference...
Dynamic Model for Analysis of Concrete Pavements
A new dynamic finite-element computer program, DYNA-SLAB, for the analysis of jointed concrete pavements subjected to moving transient loads is presented. The structural model for the...
NDE for Steel Bridges: FHWA Research, Past, Present and Future
Over the last two decades the Federal Highway Administration (FHWA) has sponsored numerous research and development projects in the area of nondestructive evaluation of steel bridges....
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...
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...
Bridge Evaluation Using a Hybrid Information System
The objective of this paper is to discuss the developments and implementation of a hybrid system consisting of a rule-based information system and hypermedia technology for use by inspectors...
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...
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:...
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...
Laser Generation and Detection of Ultrasound in Concrete
Laser ultrasonics is a non-contact nondestructive evaluation method that uses lasers to generate and detect elastic waves. In this work, laser ultrasonics is used to produce broadband...
