Overweight Trucks and Safety of Bridges
Most states face increasing pressure to issue more and heavier overweight truck permits. Current permit checking methods of many states adopt the AASHTO rating concept with or without...

Towards Structural Strength and Safety Evaluation Within Bridge Management Systems
Bridge management systems being implemented by transportation departments in the United States are limited in their ability to consider structural strength and safety when preparing recommendations...

Seismic Study of Historic Bridges in Eastern United States
The main objective of this paper is to study the Barrackville bridge and its response in resisting static and seismic loads. Since the design was based on controlled deflections, the analyses...

Methods to Control Wind-Induced Building Motions
The wind-induced response of tall buildings can be controlled by global design modifications that can be placed in three broad categories, namely, design changes in structural systems,...

Reliability of Light-Gage Metal Joist Hangers
Limit state design equations are formulated to assess the reliability of light-gage metal joist hangers using the results of experimental studies. The design equations are calibrated against...

Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...

Reliability Analysis of Stiffened Panels
This paper presents a methodology to assess the reliability against collapse of structural members, as typified by the buckling collapse of stiffened deck panels in ship structures. This...

Analysis of Unstiffened and Stiffened Tubular Members Under External Pressure and Structural Loads
This paper summarizes some important results concerning the ultimate capacity of stiffened and unstiffened tubes under combined loading. Such tubes are candidates for use in offshore structures...

Evaluation of Cast Iron Columns for Safety and Reliability
Cast iron columns exist in numerous vintage buildings. Alterations to these buildings often require analysis and modification of the structural system. This paper identifies codes that...

The Slender Tower of 52-54 East End Avenue
The structural system for the 52-54 East End Avenue project is presented. The 40 story residential tower with as aspect ratio of 12: 1 is one of the most slender buildings constructed...

LRFD vs. ASD for Wood Structures
There is a growing preference within the structural engineering community for the adoption of reliability-based load and resistance factor design (LRFD) procedures in lieu of traditional...

Imperfections and Thin-Walled Bars Behaviour
Experimental and theoretical observations allowed us to present some new conclusions concerning the proper, and safe designing of the structures composed of thin-walled bars (TWB). These...

Sensitivity and Optimum Structural Design
Modern design requires more advanced considerations leading to light and safe structures. One of the way to reach this aim is through structural optimization. Today's computational possibilities...

Design for Durability for Large Reinforced Concrete Shells
Classical design concepts restrict themselves to sufficient structural safety, using linear analysis methods. Durability questions are mainly treated independently. Modern computer simulations...

Fast Monte Carlo Simulations and Safety Index Checking
This paper presents recent techniques which require a small number of simulations to assess the structural reliability. They combine both the concept of importance zones in the random...

Digital Signal Processing Techniques for Active Structural Control
In the past, implementation of active structural control strategies employing PC-based hardware has been problematic due to excessive computational times required for processing the measured...

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...

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...

Climate Change Impacts on Boston's Water Supply
The analysis of the climate sensitivity of the water supply system of the Boston area indicates that the water supply has the potential to be dramatically altered by global warming. The...

Dam Safety Issues Related to Urban Detention Ponds
Detention ponds located within or adjacent to individual residential developments provide significant benefits by improving water quality and preventing damages from floods up to the design...
