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...

Load and Resistance Factors for Bridge Design Code
The paper summarizes the code development procedures used for the new LRFD (load and resistance factor design) bridge code. The current specifications use allowable stresses and/or load...

Effects of Site Conditions of Earthquake-Resistant Design of Structures
After a brief discussion of the importance of reliable establishment of design Earthquake Ground Motions (EQGMs) for efficient Earthquake-Resistant Design (EQ-RD) of structures, this paper...

The Use of Coda Waves for Characterizing the Site Effect on Strong Ground Motion
The well established separability of source, path and site effects on coda waves of local seismic events offers the most effective means for determining the site amplification factor empirically....

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...

Guide for the Design of Prestressed Concrete Poles
With the aim of providing engineers with some basic tools and guidelines for the design of structures, the committee prepares code and policy changes, and to expand input of manufacturers...

Overview - Electrical Substation Structures Design Guide
The ASCE Substation Structures subcommittee of the Committee on Electrical Transmission Structures (CETS) is developing a substation structures design guide. The guide discusses the analysis...

Test Experience with Heavy Angle Dead End Lattice Transmission Towers
During the past three years, the Electric Power Research Institute's Transmission Line Mechanical Research Center has conducted full scale tests on three 500kV heavy angle dead end lattice...

Assessment and Upgrade of an Older Transmission Line
This paper discusses the various tools and procedures which have been used to assess and upgrade an older 130 kv tower line. The purpose of the assessment was to determine the line compliance...

ASCE GUIDE for Design of Guyed Transmission Structures
This paper describes the contents of a new ASCE guide for the selection and design of guyed electrical transmission structures. Guyed transmission structures present unique analysis and...

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...

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,...

The Normandie Bridge
The Normandie Bridge will have one of the longest cable-stayed spans in the world, i.e. 856 m long. This paper briefly describes the design of the bridge, with the concrete access spans...
