Glitches in Flitch Beam Design
Wiesenfeld proposes a set of design criteria for flitch beams. These beams, in which wood and steel sections are bolted together to act as a single structural unit, are currently covered...
Screaming Structures
As any designer of roller coasters will tell you, civil engineering principles put the thrills and screams into roller coasters. There are two basic differences between roller coaster...
Building Onto History
In a single design/build/renovation project, an Oklahoma City AE firm acquired new offices, provided new life for an abandoned historic church building and spearheaded redevelopment of...
Classic Wood Structures
Wood has been used in a wide range of structural applications. When properly maintained, these structures can have a useful life from 50 years to several centuries. Thirty-seven unusual...
Rebuild of Ten Mile Intake Flume Structure for Electron Hydropower Project
In 1984 the Puget Sound Power and Light Company began a rebuild of what is popularly referred to as the 'world's crookedest railroad. ' The 'railroad'...
Osoyoos Lake Control Structure
The new Osoyoos Lake Control Structure has been built on the Okanogan River at Oroville, Wa. The site is about 2 miles downstream from the outlet of Osoyoos Lake, and about 9 miles south...
Load-Sharing and Reliability of Wood Systems
A methodology for the study of reliability of light-frame wood structural systems is presented. Reliability levels associated with the bending strength limit state of such systems are...
Lifetime Reliability of Wood Structural Systems
A model to predict ultimate capacity reliability of wood systems is developed. The model is analogous to Markov cumulative damage models. System ultimate capacity is defined as failure...
An Investigation of the Supports of a Water Main
Two 48 inch (1. 22 m) diameter cast iron pipes constructed 50 to 70 years ago form a major part of the potable water transmission system of Atlantic City. For the most part of their length,...
Load and Resistance Factor Design for Engineered Wood Construction
A Pre-Standard Report
The information contained in this pre-standard report is intended to provide guidance to writers of a load and resistance factor design (LRFD) specification for engineered wood construction....
A Clean Up in Slow Motion
Eight years have passed since contamination was first discovered at the Valley Wood Preserving plant in Turlock, Calif. Though severe chromium contamination continues to travel toward...
Port of Eastport, Maine: A Growing Breakbulk Cargo Port (
The Port of Eastport accommodated over 90,000 tons of international waterborne trade in 1986. In 1980, this trade-related port operation was non-existent. A Cargo Facility Economic and...
Establishing Native Plant Communities on a Coastal Landfill, Berkeley, California
Three native coastal plant communities were successfully established in a park created on a landfill site on San Francisco Bay: coastal strand, coastal scrub, and prairie grassland. The...
Homer Spit Storm Damage Reduction
Homer Spit is a natural spit formed by littoral processes at the confluence of Kachemak Bay and Cook Inlet in Southcentral Alaska, some 192 km southwest of Anchorage. The immediate erosion...
The Chicago Lakefront Plan - 1986
Although Chicago is considered to have one of the world's most beautiful and also stable waterfronts, much of its shore protection is in imminent danger of failure. Nearly...
Timber Bulkheads
Timber bulkhead design and construction methods are presented in this publication for consideration by the engineering profession. Included are papers on an analytical method for the design...
Structural Engineering and Microcomputers
This publication contains five papers on the use of microcomputers by structural engineers. The first paper discusses the design of multi-story rigid steel frames. The design process employed...
Overview of the Guidelines for T/L Structure Loadings
This section introduces a reliability based design methodology that forms the framework for the loading guidelines. A Load and Resistance Factor Design (LRFD) format is presented for the...
Development and Use of Stress Laminated Timber Deck Bridges
This presentation provides a brief overview of the concepts, development, research needs, economics and recent use of stress laminated timber bridge decks. Repeated articles on the serious...
Micro=Lam? LVL: A New Alternative for Timber Bridges
Laminated veneer lumber (LVL) provides a unique opportunity to obtain large structural members from ever-smaller trees. It provides the added benefit of high treatability. This paper explains...
