Marta North Line Midtown Station
This paper presents a case study of a cast-in-place concrete rapid transit station structure. Attention is focused on the performance of the monolithically connected, three-dimensional...
Shock-tested R. C. Slabs: Significant Parameters
Shock-tube tests of plain concrete and reinforced concrete (R. C.) slabs were performed. The influence of free water in concrete pores, emphasized in previous tests at a material level,...
Strut-Tie Model Design of Disturbed Regions in Concrete Structures
The design of disturbed (highly non-linear behavior) regions in concrete structures is illustrated using strut-tie approach. The use of this approach assisted with interactive computer...
Behavior of RC Beams under Sustained Load
Experimental results of eight reinforced concrete beams under 3-month's sustained load, with the ratio of shear span to depth equal to 2.5, are reported. It is shown by tests that the...
Impulsive Punching of Fiber-Reinforced Concrete Slabs
The behavior of FRC slabs reinforced with polymeric fibers (polyacrylonitrile fibers PAN) and subjected to impulsive punching is analyzed here in order to clarify to what extent the fibers...
FRP Box-Beams Under Long-Time Static and Fatigue Loading
This paper discusses experimental and analytical aspects of the long-time behavior of filament wound E-glass fiber reinforced epoxy-box-beams. Theoretical and experimental data are compared...
Local Buckling of Pultruded FRP Beams: Theory and Experiment
A continuing experimental and theoretical investigation of the local compression flange buckling of commercially produced pultruded fiber-reinforced plastic (FRP) beams is briefly described...
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...
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...
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...
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...
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...
Cut and Cover Construction of the SSC Injector Tunnels
The injector system of the Superconducting Super Collider (SSC) constitutes the string of tunnels where protons are accelerated to near the speed of light and injected into the main collider...
An Overview of Shotcrete Usage on the SSC
Shotcrete has been widely used on the Superconducting Super Collider for initial support of tunnel excavations in both the strong and weak rock formations encountered. Different types...
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....
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...
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...
Seismic Response and Retrofitting of Non-Ductile Reinforced Concrete Bridges
The Interstate I5/I605 Separator in Los Angeles County was severely damaged during the October, 1 1987 Whittier Narrows Earthquake. This damage included non-ductile shear failure in the...
