Recent Developments in Seismic Response of Composite Structures
Lack of sufficient data has limited a wider application of structures using mixed steel-concrete construction in seismically active regions. This paper summarizes some recent studies at...
One Peachtree Center: Atlanta Georgia
Presented in this paper are the architectural and structural concepts of One Peachtree Center built in the city of Atlanta. This 62-story tall building has changed the downtown skyline...
One Ninety One Peachtree and NationsBank: Composite Additions to the Atlanta Skyline
The structural design of two composite buildings in Atlanta is described in this paper. A composite exterior partial tube was used in one case and a composite super-column system was utilized...
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...
Talmadge Bridge Replacement
This paper discusses the design of the main spans and approach spans for the replacement of the Talmadge Bridge for the Georgia Department of Transportation. The design of the concrete...
Comprehensive Reliability Analysis of Prestressed Concrete Beams
Using second moment methods, the reliability with respect to several limit states for seventy three prestressed concrete beams is assessed. These beams that are extensively used in the...
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...
Stability of Lift Slab Structure During Construction Stage
The lift slab structures impose stability problems during the construction phase. The process of constructing this type of structure requires placing the masses of the floor slabs at a...
Comparison of Bridge Deterioration Rates
This paper presents the results of a study of rates of deterioration of steel and prestressed concrete bridge superstructures. The results indicate that age is the primary determinant...
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...
Continuity in Precast Prestressed Concrete Girder Bridges
An experimental study conducted to evaluate the behavior of pretensioned bridge members made continuous with a cast-in-place concrete slab and diaphragm is summarized. In this study, the...
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,...
Strength Variability of Wood Formwork Members
Failure of concrete formwork is one of the main causes of concrete construction failures. Among the main causes of formwork failure is inadequate strength. Currently there is no published...
