Use of New Liner In Water Distribution System
For years there has been interest in rehabilitation of water distribution systems to provide quality drinking water and to reduce breaks in the water system service. Much work has been...
Making the Most of HPC
Developing high-performance concrete (HPC) was only the first step toward bringing a material with improved durability, strength, constructability, and mechanical properties to the bridge...
Monitoring Two Tunnels
Two pilot projects for bored tunneling in soft soil have been undertaken in the Netherlands under the authority of the Centre for Underground Construction: the Second Heinenoord Tunnel...
Modeling of Inelastic Behavior of RC Structures under Seismic Loads
Proceedings of the U.S.?Japan Seminar on Post-Peak Behavior of Reinforced Concrete Structures Subjected to Seismic Loads: Recent Advances and Challenges on Analysis and Design, held in...
Symptom-Based Reliability of Aging Infrastructure Systems
Ideally, aging infrastructure systems should be monitored for safety and repaired in case of need. Eventually, authors believe that symptom-based reliability will be useful for safety...
Maintenance of Diaphragm-Girder Connections
Fatigue cracking at diaphragm-girder connections and at similar connections of cross-frames and floorbeams have been common in steel highway bridges for the past 20 or 30 years. Fatigue...
New Concepts in Structural Strength Assessment for Large Buildings in Fire
This paper presents theoretical descriptions of the key phenomena that govern the behaviour of composite framed structures in fire. These descriptions have been developed in parallel with...
High Performance Dampers for Bridges
A multi-disciplinary research study investigates the use of shape memory alloys as seismic dampers in bridges. Shape memory alloys are a class of alloys that display several unique characteristics,...
New Developments in the Field of Seismic Isolation
This paper will concentrate onwhat likely, is the most significant of these issues: changes in the mechanical properties ofseismic isolation and energy dissipation hardware as they are...
Cyclic Behavior of Three-Dimensional Partially-Restrained Composite Connections
This paper describes the test of a full-scale, bi-directional, PR composite beam-to-column connection. The PR connection consisted of continuous reinforcement bars across the column and...
Structural Lumber from Small-Diameter Western U.S. Softwood Trees
The purpose of this study was to determine the mechanical properties, and corresponding economic value, of dimension lumber produced from selected over-stocked forest stands of small-diameter...
Under the Microscope
Forensic engineering is typically more complex than engineering design because it requires the integration of specialized knowledge of materials science, structural analysis and design,...
Terminal Island Turnaround
The Pier T marine terminal at the Port of Long Beach is a new 375-acre (152 ha) container terminal being developed at the former Long Beach Naval Station and Naval Shipyard. The $525-million...
Concrete Delivers
The latest addition to the skyline of Shanghai, China, is a strikingly slender all-concrete 62-story office tower. It is the city's tallest all-concrete building, achieving...
Composites Enhance Timber Bridges
Two relatively new technologies are available for reinforcing or strengthening timber bridges with fiber-reinforced polymers (FRPs). The first consists in reinforcing the tension side...
Dual Benefits
When the Port of Houston needed to be dredged to accommodate larger commercial vessels, engineers decided to put the dredged material to use to create wetlands and islands that will serve...
The Road to Reuse
Many types of wastes and by-products have potential uses in the highway environment. Applications for recycled materials include asphalt pavement, portland cement concrete pavement, granular...
Liner Lessons
The County Sanitation Districts of Los Angeles County comprise 25 independent special districts that cover a service area of approximately 770 sq mi (1,990 km�). Since the early 1990s...
Bridge to the Future
An arched footbridge under construction in Seoul, South Korea, that is reconnecting the metropolis with a tranquil island, will demonstrate the compressive strength and sleek design potential...
Megaproject Management
By the dredging and landfill project manager for the Port of Los Angeles and Alan E. Alcorn, P.E., an associate vice president of Moffat and Nichol Engineers in Los Angeles. The Pier 400...
