Steel Compression Member Design in the 1994 Canadian Standard
The 1994 edition of CSA Standard S 16.1-M94, Limit states design of steel structures (CSA 1994) contains explicit methods for computing the compressive resistance of monosymmetric and...

Innovative Design of Steel Gable Frames
Common wisdom holds that conventionally designed gable frames fabricated from rolled sections cannot compete with metal building system frames fabricated from plate and bar stock, from...

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...

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...

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...

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...

Externally Stiffened I-Beam to Box-Column Connections
This paper is concerned with I-beam to Box-column connections stiffened externally. Experimental and theoretical findings on full-scale connection models are highlighted. The performance...

Investigating the Behavior of a Lattice Structural Section
Tests were conducted on a fully instrumented lattice section assembled using various connection types (bolted or welded). The results of this study show that bolt slippage can have a major...

Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...

Fires Deemed to Have Tested Structural Performance
This paper provides an overview and progress report of a survey and study of fire incidents deemed to have tested the structural performance of large buildings. This ongoing effort was...

Consequential Fire Loads on Structures
Much less consideration has been given to the performance of modern structural and architectural systems during fires and to the minimization of damage that threatens the integrity of...

Synopsis of a Manual on Structural Fire Protection
Structural Fire Protection : Manual of Practice was published in 1992 by the American Society of Civil Engineers. The Manual has two major parts. Part I (Chapters 1 to 3) introduces the...

Estimation of Structural Damping of Buildings
The full-scale data on damping ratio are collected from 77 buildings within Japan. Almost all data are obtained from vibrations with a very small amplitude such as microtremor, man-power...

Earthquake Barrier Technology: Sliding-Friction Energy Dissipation
The first project in America to use friction damping was approved by the City of Los Angeles for the retrofit of a 10-story concrete frame building, designed to resist a Maximum Credible...
