Code Provisions for Unreinforced Masonry Bearing Wall Buildings in California
Prior to the Long Beach earthquake of 1933, unreinforced masonry (URM) construction was usual in California, as it still is in many areas of the United States. The poor performance of...
CenterCore Strengthening System for Seismic Hazard Reduction of Unreinforced Masonry Bearing Wall Buildings
The CenterCore technique of reinforcing unreinforced masonry walls was developed with the help of a National Science Foundation grant in 1984. The CenterCore strengthening system consists...
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...
The Effective Use of Fire Ratings
Any consideration of components for construction must take into account the performance of those components when they are exposed to fire. Codes, standards, and fire ratings provide some...
Things That Fall?Lessons from Some Construction Accidents and Structural Failures
The causes and results of several construction accidents are reviewed. The lessons to be learned from such a summary are that all too often the simplest oversight leads to catastrophic...
85 Stories in Kuala Lumpur?The 5th and 6th Tallest Buildings in the World
A concrete core and cylindrical concrete tube structure provides a safe, elegant, efficient and constructible solution to the challenge of designing the world's 5th and 6th tallest buildings,...
Mitigation of Wind-Created Risks During Construction
Wind damage to structures during construction has been found to be significant and often catastrophic. Structural failures are often the result of wind loads that are far less than the...
Investigation of Diaphragm Walls to Improve Performance, Design, and Construction
As a result of the need for tunnels, underground highways and parking structures, cofferdams, facilities related to the improvement of the environment, etc., there has been a significant...
Behavior of Horizontally Curved Steel Highway Bridges
Horizontally curved highway bridges represent up to 25 percent of the market for new steel-bridge construction each year. However, unanswered questions remain concerning the fundamental...
Design of the Main Bridge of the Huachiang Bridge
The Huachiang Bridge will be reconstructed by erecting the deck structure in two steps to avoid reducing or interfering with the bridge's traffic flow. Both the analysis and the detailed...
Superlong Cable-Stayed Bridges
Superlong cable-stayed bridge span is defined as one over 1000 meters. Problems requiring special attention regarding these bridges are discussed, namely: excessive cable sag; high axial...
Developing a New Construction Policy for Bridge Management
The SHRP Program and other rehabilitation strategies are based on extending the life of concrete bridge elements. In the Bridge Inventory are a number of bridges that must be reconstructed....
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...
Reliability-Based Expert Systems for Optimal Maintenance of Concrete Bridges
In this paper ongoing research in the CEC supported BRITE/EURAM project P3091 is presented. In the project reliability based expert systems for inspection and maintenance of corroded reinforced...
Reliability of Highway Bridge Piers
Structural safety of reinforced concrete bridge piers supporting highway traffic is studied. Reliability indices for flexure, shear, and combined flexure and axial load limit states at...
Recent Successes in Welding Jumbo Shapes
A rather unique structure utilizing jumbo shapes was recently designed and fabricated. The structure was 100% welded according to the specifications for welding jumbo shapes recently developed...
Design of Monosymmetric Sections in Flexure
Monosymmetric members are generally I-shaped, symmetrical about the plane of the web, and characteristically have a larger compression flange than tension flange. Examples are crane girders...
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...
