FRP Box-Beams Under Long-Time Static and Fatigue Loading
This paper discusses experimental and analytical aspects of the long-time behavior of filament wound E-glass fiber reinforced epoxy-box-beams. Theoretical and experimental data are compared...

Progress in Reinforced Concrete Column Design: An Introduction
The Joint ASCE-ACI Committee 441 on Reinforced Concrete Columns is investigating a number of problems related to structural behavior and design of reinforced concrete columns. This paper...

Rational Limits for Longitudinal Steel in Concrete Columns
Current limits for the amount of longitudinal reinforcement in concrete columns were established more than 60 years ago. Commercial grades of reinforcement in 1930 were about half as strong...

High-Strength Concrete Columns: State of the Knowledge
This paper consists of reported information divided into two general categories, performance of High-Strength Concrete (HSC) columns under concentric loads, and combined axial and bending...

Use of Composite Timber-concrete Floors in Residential Buildings
Timber-concrete floors are widely used in the Gulf region for its resistance to hot and aggressive environment of the area. However, due to the fact that no shear connector is provided,...

The Canadian Approach in the Design of Wood Structures: Conversion to Limit States Design
During the early 70's, the National Building Code of Canada (NBCC) established the principle that structural design be carried out using the limit states design (LSD) method. The technical...

Evaluation of Wood Floor Vibration Design Criteria
In the United States, floors in wood buildings are designed according to strength and deflection criteria under static uniform loads. With the introduction of engineered joist products...

Strength Variability of Wood Formwork Members
Failure of concrete formwork is one of the main causes of concrete construction failures. Among the main causes of formwork failure is inadequate strength. Currently there is no published...

Seismic Behavior of Type PR Steel Frames
Type PR(partially restrained 'simple framing') is one of the methods of design specified in the AISC LRFD(1986) Design code for the design of unbraced steel building frames. In this method...

Design Guidelines for the Use of Debonded Strands
In this paper, presented are the flexural tests performed on beams containing debonded strands. Results show that debonded strands can be used reliably and safely, stipulating that the...

Development Length of Uncoated Prestressing Strand
The Federal Highway Administration is conducting ongoing research which investigates the development length of uncoated and epoxy coated prestressing strand in prestressed concrete members....

Mechanical Behavior of Dowels Embedded in Concrete
In this paper an experimental investigation on the behavior of dowels embedded in concrete is described. The dowel strength under monotonic forces with two different boundary conditions...

Lateral Load Resisting Systems for Circular Buildings
The design of structural systems to economically limit inter-story drift and building acceleration for circular high rise buildings is presented within the framework of two recently constructed...

Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...

Probabilistic Evaluation of Human Perception Threshold of Horizontal Vibration of Buildings (0.125Hz to 6.0Hz)
Vibration perception tests are conducted both for low frequencies of high-rise buildings and high frequencies of low-rise residential buildings. The vibration frequency is varied from...

Methods to Control Wind-Induced Building Motions
The wind-induced response of tall buildings can be controlled by global design modifications that can be placed in three broad categories, namely, design changes in structural systems,...

Research and Development ? Why bother?
As the world becomes a true global marketplace, the ramifications of this change is felt in all aspects of business. Products and services from around the world are beginning to appear...

A Self-Balancing Laminate
A self balancing wood laminate has been developed based on the principle of orthotropic elasticity. Lumber is cut into three sections in the flatwise plane and each side member is turned...

Metal Truss Plates: Less than Full-Depth Penetration and Shear Buckling
This paper presents the results of two experimental studies on metal truss plates which are used to join members of wood trusses. The first study investigated the effect that less than...

Natural Decay Resistance of Glued-Laminated Beams
The natural decay resistance of untreated Douglas-fir heartwood specimens sampled from glued-laminated beams was evaluated using a modified agar plate test modeled after the European Standard...
