Design of Lateral Steel in Columns
Lateral steel in columns is generally required for shear resistance, confinement of concrete and prevention of buckling of longitudinal bars. This paper is limited to the design of lateral...
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...
Progress in Reinforced Concrete Column Design
This paper reviews some of the design procedures used for both braced and unbraced frames constructed in reinforced concrete. The discussion refers to the problems of material and geometric...
Proposed Hurricane Wind Speeds for ASCE 7-95
A 2-3 second peak gust wind map has been proposed for the wind load provisions of ASCE 7-95, now in draft form. On the hurricane coast, speeds from published Monte Carlo analyses were...
A Study of Jointless Bridge Behavior
The pressing need for maintenance free and low construction cost bridges, has increased the interest and activity in building integral or jointless bridges. The investigation of the behavior...
Design of Box Girder Bridges by Nonlinear Theory
A modified design procedure applicable to a large number of conventional box girder bridges with longitudinally-stiffened flanges has been presented in this paper. It determines the ultimate...
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,...
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...
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...
LRFD Provisions for Wood Bridges
A project to develop a load and resistance factor design (LRFD) edition of the American Association of State Highway and Transportation Officials (AASHTO) Standard Specifications for Highway...
Unified Code Provisions for Concrete Bridges
Provisions on limiting the flexural reinforcement adopted in the new AASHTO LRFD Specification for Bridge Design are summarized (1). They address minimum and maximum levels of reinforcement...
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...
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...
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...
Response of Stressed Timber T - and Box-Beam Bridges
The objective of this study is to establish the strength, stiffness, and transverse load distribution factors of stressed timber T-, Bulk T-, and Box-beam bridge systems. To achieve the...
SDC Detector Foundation Requirements for the SSC
The Solenoidal Detector Collaboration (SDC) detector weighs approximately 32,000 metric tons, and its ability to perform to design specifications is directly related to its internal alignment....
Uniform Lateral Load Capacity of Infilled Frames
Three tests were conducted on 2.4 meter by 2.4 meter steel frames infilled with structural clay tile to determine the behavior and capacity when subjected to uniform lateral loads. An...
Dynamic Testing of Unreinforced Brick Masonry Infills
A significant seismic hazard may exist when unreinforced masonry infill panels fall out of their surrounding frames as a result of excessive accelerations applied normal to their plane....
