Architecture and Lightweight Structures: A Methodical Design Approach
Lightweight structures such as membrane structures, shells, space-grid, lightweight trussed and suspended structures have become an integral part of the international building scene. While...

Representing Design Cases Based on Methods
This paper discusses an approach to representing design cases using the methods used in solving specific design problems. This differs from the conventional representation of design cases...

Multimedia Based System for Analyzing Production Organizations
Construction operations involve many complex operations and relationships. This paper deals with data gathering for productivity improvement-studies, process modelling and simulation of...

Computer Analysis of Lateral Loading in Wood-Framed Structures
Building codes and design techniques associated with single-family housing need to incorporate advances in architecture and construction so that the traditional life-safety building codes...

Measured Downdrag on Seven Coated and Uncoated Piles in New Orleans
A site outside of New Orleans, Louisiana was selected as part of a research effort to study the phenomenon of downdrag on bitumen-coated piles. Two steel pipe piles, two timber piles,...

Model of an Upgrade
As further studies and more extensive computer models help engineers better understand the workings of wastewater treatment plant processes, those engineers are finding more efficient...

In Rehab We Trust
Glulam structures will be durable and last for a long time provided structural elements are protected from water and moisture. Once water is allowed to come into direct contact with glulam...

The Mexican Migration
The North American Free Trade Agreement has made Mexico an attractive market for U.S. firms, particularly in the environmental field. At the same time, privatization (as with toll roads...

Connectors for Earthquake Resistant Structures
Damage assessments from the past several earthquakes located on the northern, central and southern zones of the San Andreas Fault - Cape Mendocino: April 1992, 7.1; Loma Prieta: October...

The European Approach to Seismic Design of Engineered Timber Constructions: The Case of Low-Dissipative Structures
In the present paper the importance of the dissipated energy on the actual structural behaviour of low-dissipative structures as glulam portal frames with mechanical fasteners under seismic...

A General Hysteresis Model for Wood Structures
To predict the dynamic response of a wood structure, its energy dissipation mechanism and hysteresis behavior must be appropriately modeled. This paper presents a new hysteresis model...

Fire Retardant Treated Wood
The paper explains how FRTW chemicals react with combustible gases. It describes the two types into which FRTW is divided. Misconceptions about FRTW are also addressed....

Fire Endurance Model for a Metal-Plate-Connected Wood Truss
A numerical model has been developed for predicting the fire endurance of a single metal-plate-connected wood truss. Extensive component fire testing was conducted to develop the necessary...

Nondestructive Evaluation of Timber
Nondestructive evaluation of materials, the science of identifying the physical and mechanical properties of materials without altering their end-use capabilities, is valuable in defining...

New Views for Modeling Dynamic Response of URM Buildings
Various computational models are used to depict seismic response of an unreinforced masonry building that was subjected to the 1989 Loma Prieta Earthquake. The worthiness of various analytical...

Design Property Values of Wood-Based Materials in LRFD Format
The development of a U.S. Load & Resistance Factored Design (LRFD) specification and supporting documents for engineered wood construction is nearing completion. The two key components...

Design of Connections in Wood Structures: LRFD vs. ASD
This paper provides a comparison of connection design capacities using load and resistance factor design (LRFD) procedures and allowable stress design (ASD) procedures....

Wood Diaphragm Design Capacities in LRFD Format
Wood diaphragms (horizontal and vertical) have performed well in resisting and transferring lateral forces imposed by major wind and seismic events. Resilient (ductile) behavior of wood...

System Factors in LRFD Format: A Multidimensional Judgment Call
A Load & Resistant Factor Design Specification for wood buildings is being completed. The Specification contains several revisions from the traditional 'repetitive member' factor...

Wood Bridge Design Using AASHTO LRFD Specifications
A nationwide project to develop a load and resistance factor (LRFD) design edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications...
