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...
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...
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...
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...
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...
Cyclic Behavior of Joints Between Steel Beams and Reinforced Concrete Columns
The design and behavior of composite beam-column joints for seismic design are reviewed based on the results of tests. Issues addressed include the strength, deformation, and toughness...
Rigid Beam-To-Column Connection Detail for Circular Composite Columns
Steel pipes with relatively thin wall thickness and filled with high strength concrete have been used in building construction. Some of the advantages of this type of column include eliminating...
Design of Frames Using Notional Horizontal Force
The cantilever columns and portal frames are studied by using the notional horizontal force design concept. This concept intends to eliminate K-factor in the frame design. It was found...
A Nonlinear-Analysis-Based Procedure for Evaluating Load-Carrying Capacity of In-Plane Steel Frames
A simple method based on geometrically nonlinear analysis is proposed to evaluate the load-carrying capacity of a steel structure. The effects of material nonlinearity and residual stress...
Acoustic Emission Monitoring of Fatigue Crack Growth in HSLA-80 Steel Box Beams
An acoustic emission is a transient elastic wave generated by the rapid release of energy from a localized source within a material. There can be many sources of acoustic emission in a...
Seismic Retrofit of R/C Columns with Inadequate Lap Splices
This paper presents experimental results on the use of rectangular steel jackets to improve the seismic performance of rectangular steel jackets to improve the seismic performance of rectangular...
Column and Beam-Column Design - A World View
This paper is concerned with the design of columns and beam-columns in steel building frames. Design provisions found in some selected codes viz. AS DR87164 87(Australia), BS5950 Part...
Some Aspects of Compression Member Design in Australia
The paper summarizes and elucidates the provisions of the Australian Standard AS4100-1990, Steel Structures, for the design of compression members. Emphasis is placed on those aspects...
Optimization of Controlled Structures: Using
This paper presents the algorithm for the design of a controlled structure in which the structural and control systems are designed simultaneously. The problem is posed as an optimization...
Controlling the Seismic Behavior of Precast Concrete
Precast concrete has, through the years the years, acquired a bad reputation insofar as its ability to withstand earthquake is concerned. This reputation, though reasonably based, is not...
Seismic Performance Behavior of Precast Concrete Beam-Column Joints
The experimental test program being conducted at the National Institute of Standards and Technology on 1/3-scale model precast concrete beam-to-column connections is summarized. The objective...
Assessment and Testing of Column Lap Splices for the Santa Monica Viaduct Retrofit
This paper describes assessment and the full-scale test of a 3 ft. (914 mm) dia. column containing #11 (34.9 mm dia.) reinforcing steel lap-spliced in the critical region. The column modelled...
Seismic Strengthening of R/C Columns Using Steel Jackets
This paper presents experimental results on the use of steel collars and steel jackets as a retrofitting system to improve the seismic performance of short rectangular reinforced concrete...
Cyclic Behavior and Seismic Design of Steel Base Plates
The objectives of this study were to conduct realistic experiments to understand cyclic behavior of steel column base plates and to develop seismic design recommendations. Six specimens...
Some Unresolved Issues in Seismic Steel Codes
In the latest revisions of the three major U.S. seismic codes (AISC, NEHRP, UBC) some requirements can be questioned because of limited knowledge. Confining attention to conventional kinds...
