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...
Testing of Concrete Curtain Wall Panels Reinforced with FRP Grids
The objective of this paper is to evaluate the suitability of Fiber Reinforced Plastic (FRP) grids for use as a structural; reinforcement in concrete curtain wall panels. This paper describes...
Bulb-T and Glulam-FRP Beams for Timber Bridges
In this paper, we discusses the manufacturing, analysis, and testing of two glulam beam designers:(1) Southern pine bulb, and (2) yellow-poplar reinforced with pultruded fiber-reinforced...
Design and Construction of Post-Tensioned Concrete Floor Systems
This is a summary of the original full length paper which is available from the author. This paper assumes a basic technical knowledge of reinforced concrete design and prestressed concrete...
Anchorage of Non-Metallic Prestressing Tendons
Experimental confirmation tests were conducted to evaluate mechanical and epoxy socketed anchors for fiber reinforced plastic (FRP) prestressing tendons. The studies found that a parabolically...
Nonlinear Analysis of Prestressed Concrete Structures
This paper presents a finite element model for the nonlinear analysis of prestressed concrete structures. The model can be used to analyze pretensioned or posttensioned, bonded or unbonded...
Recent Advances in 3D Non-Linear FE-Analysis of R/C and P/C Beam Structures
A new simple modelling of interface problems in non-linear FE-analysis of reinforced concrete (R/C) and prestressed concrete (P/ C) structures is presented. It consists in taking account...
Seismic Behavior of Non-Ductile Concrete Frame Structures
Non-ductile reinforced concrete (RC) frame structures designed and constructed during the 1950's through 1970's exist in many regions of the United States. The frames of these structures...
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...
Damage Prediction in Reinforced Concrete Structures under Cyclic Loading
Assessment of the stiffness, resistance and damage behaviour of reinforced concrete members under high cyclic loading due to earthquake actions must consider material nonlinear effects...
Blast Demolition of Reinforced Concrete Industrial Chimneys
On some of recently demolished chimneys, transient measurements were taken, in the vicinity of the tilting hinge, during the process of falling down. Thus, corresponding dynamic computational...
