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...
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...
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...
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...
Construction of the Clark Cable-Stayed Bridge at Alton, Illinois
The Clark Cable-Stayed Bridge crosses the Mississippi River at Alton, Illinois. The successful bid by McCarthy Bros/Clark Bridge JV was for the steel alternative. The bridge design included...
The Tatara Bridge - World's Longest Cable-Stayed Span
The Tatara Bridge now under construction has the main span length of 890m which will be the world's longest in cable-stayed bridges when completed. Except for certain lengths of prestressed...
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...
Creep Analysis of Composite Steel-Concrete Members with Deformable Connectors
The long-term analysis of composite steel-concrete beams with elastically deformable connectors is presented. The basic integro-differential equation governing the problem is solved by...
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...
A Peice-wise Linear Evaluation of Masonry Infills Subjected to Out-of-plane Seiesmic Drift
This paper summarizes the out-of-plane testing and analytical modeling of a full-scale unreinforced masonry (URM) infilled frame and a bare frame without infilling. The testing was part...
Seismic Strengthening of URM Buildings with Steel Bracing
Unreinforced masonry (URM) buildings with large open fronts are extremely vulnerable to seismic inputs posing serious life safety hazard. Steel bracing systems have been used to upgrade...
Steel-Concrete Interaction by Means of Film Sensors
By adapting a recently-developed technique based on the piezoelectrical properties of relatively thick films made of Polyvinyldifluor organic composites and extensively used in robotics,...
Load Carrying Capacity of SPC Composite Column
This paper reports the result of beam column test of a new type composite columns. High-strength precast-concrete panels (hereafter denoted as PCa-panels) are fixed to the steel square...
Dynamic Response of Steel Fiber Reinforced Concrete
Extensive research has been done on the static properties of steel fiber reinforced concrete, but very little on the dynamic properties. A total of 20 beams was tested. The steel fiber...
High-Strain Kinetic Testing of Deep Foundations
High-strain kinetic testing involves the upward decelerating or accelerating of a mass and using its inertial force to axial prolonged pulse at the head of a pile. Currently available...
Low Strain Dynamic Testing of Wood Piles Supporting an Existing Pier
This paper presents a case history where low strain dynamic testing was performed to test wood piles supporting an existing structure. Under consideration is a 183 m long wooden pier constructed...
Some Aspects of Determination of Pile Capacity by the Wave Equation
This paper presents some new observations made during correlation study of pile capacity computed by wave equation analysis with failure load from static test. In order to determine proper...
Timber Pile Length Determination Using a Nondestructive Technique
Determining timber pile length is critical when evaluating the potential effects of scour and for determining pile capacity. Unfortunately, records of timber pile lengths are typically...
