Large Woody Debris Effects on Channel Friction Factor
A simple method for quantifying large woody debris (LWD) density and computing associated friction factors was developed and tested using data from the South Fork Obion River in western...
Safety Analysis of Handset Wood Slab Formworks
A reliability index is calculated for flexural strength of a handset wood slab formwork system. Load and resistance models are based on a survey of construction loads and wood test data...
Limit States Design of Wooden Formwork for Concrete Walls
Load and resistance factors are developed for ultimate limit states design of wooden formwork components for concrete walls when the lateral concrete pressures are computed using the ACI...
Dissolved Oxygen and Woody Debris: Detecting Sensitive Forest Streams
Early watershed studies showed that timber harvesting and yarding could depress dissolved oxygen in nearby streams when fresh slash entered streams and streamside shade was reduced. State...
Caring for a Covered Bridge
Today the quaint Cornish-Windsor covered bridge (winner of this year's Outstanding Civil Engineering Merit Award) doesn't look much different than it did when...
Access Floor Response Spectra for Equipment Line-Ups in Telecommunications Central Offices
Modern telecommunications central offices very often utilize access floors to support equipment line-ups. An analytical study was carried out to study the seismic response of equipment...
The U.K. Marina Industry?An Overview
This paper is written from the point of view of an established marina developer and operator and, as the title suggests, it purports to be nothing more than an overview of a number of...
Pressure-Treated Wood Effect on Marina Environment
Pressure treated Southern Pine and Douglas Fir are the most commonly used materials for marina construction in the United States. The preservatives currently used, creosote, chromated...
Guideline for Structural Condition Assessment of Existing Buildings
Changing economic conditions, concerns for historic preservation, emphasis on fully utilizing conveniently located structures, space shortages, and increasing cost of materials and products...
Practical Aspects of Structural Control
Several problems in the practical implementation of structural control are discussed herein. These problems include the prediction of the actual behavior of existing structures, mathematical...
Stochastic Finite Element Analysis of Metal Plate Connected Wood Trusses
A stochastic finite element approach is developed for use in ananlyzing metal plate connected wood trusses. The procedure uses linear beam-column elements to model the wood members. The...
Responses of a Secondary System and Its Supporting Hysteretic Structure to Seismic Excitations
We consider an N-story building that supports 1-degree-of-freedom equipment on one of the floors, and examine both the building's and the equipment's responses...
Open World Problems in Structural Reliability
A closed world model represents total knowledge about everything in a particular system. An open world model represents partial knowledge where some things are known to be true, some are...
Structural Reliability of Wood Beam-Columns
A formulation for reliability-based design procedures of wood columns and beam columns is presented. The load carrying capacity of these structural members is obtained using a non-linear...
LRFD for Engineered Wood Construction: ASCE Pre-Standard, Wood Industry Initiative
The structural wood community in the United States is in the process of developing a reliability-based consensus Load and Resistance Factor Design (LRFD) standard for engineered wood construction....
Lifetime Behavior of Wood Structural Systems
Reliability based design of wood structural systems requires knowledge about the lifetime behavior of the system. The 50 year lifetime behavior of wood floors and flat roofs was examined...
Structural Reliability Through Machine Learning From Case Histories
The development of a management tool for the control of structural safety is described. Artificial intelligence techniques of 'machine learning' are employed...
On the Drawing Board
Reliable and quantitative nondestructive evaluation (NDE) methods for construction materials of wood, concrete, masonry and structural steel are needed. NSF program director John Scalzi...
Environmental Design of Channels?Can It Be Done?
The importance of environmental features to channel design is generally accepted and procedures for incorporating environmental features into flood control channel design have been developed....
Structural Wood Products
This paper provides a description of available structural wood products. Traditional products such as lumber and plywood are being supplemented by new products that include composite lumber...
