A Dome For the 21st Century
Putting a circular dome on a square building--the classical architectural design challenge--takes on new proportions at the Federal Building and Courthouse in Charleston, W. Va. The 170...
High-Strength Concrete Columns in High-Rise Buildings
Strength and ductility of high-strength concrete columns were investigated by examining available test data. The results are summarized in terms of load and ductility capacities of columns....
Composite Walls as Shear Elements in Tall Structures
This paper describes a system of composite walling that can be used as a lateral load resisting system in tall structures. The composite walling comprises two skins of profiled steel sheeting...
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...
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...
Seismic Performance of Railway Bridges
Historically, the seismic performance of railway bridges in the U.S.A. has been very satisfactory during earthquakes of this century. There are many possible factors contributing to this...
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...
Proposed Hurricane Wind Speeds for ASCE 7-95
A 2-3 second peak gust wind map has been proposed for the wind load provisions of ASCE 7-95, now in draft form. On the hurricane coast, speeds from published Monte Carlo analyses were...
Averaging Time and Maximum Speeds in Hurricanes
This paper discuses wind speed data obtained during Hurricane Andrew around Miami International Airport, at six anemometer locations which make up the wind shear warning network. Data...
Hurricane Windspeeds at Inland Locations
A critical review of the windfield and filling models used in the hurricane simulation procedure of Batts et al. [1980] clearly indicates that the hurricane windspeeds they obtained for...
Lateral Load Resisting Systems for Circular Buildings
The design of structural systems to economically limit inter-story drift and building acceleration for circular high rise buildings is presented within the framework of two recently constructed...
Criteria for Acceptable Wind-Induced Motions
This paper discusses criteria for evaluating acceptable wind-induced building motions. The paper draws on the results of moving room experiments and the performance of actual buildings...
Practical Application of Tuned Liquid Damper for Tall Buildings
Performance of TLD, based on the full-scale measurement of an actual tall building, is discussed in this paper. Wind induced vibration of the SYP Tower was measured during a gusty day,...
Instrumentation and Testing of a Three Hinge Arch for Service Loads Increase
A three hinge arch railroad bridge was instrumented and tested to evaluate its condition and the required modification for increasing the service loads. Initially the structure was designed...
Field Tests of Railway Bridges
A research program focused on the evaluation of railway bridges has been underway for the past five years. The objectives of a research are as follows: (1) determine the loading spectra...
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...
A Probabilistic Approach to the Response of Tall Buildings to Wind Loadings
Tall buildings constructed in recent years are light in weight, flexible and low in damping. This is the consequence of using lighter material with higher strength, and fewer interior...
Gust Speeds in Hurricanes
Based on strip-chart records of wind speeds representing 11 recording stations and four hurricanes, it is concluded that gust factors for hurricanes generally exceed the gust factors proposed...
Extreme Winds Estimation by `Peaks Over Threshold' and Epochal Methods
With a view to applying the 'peaks over threshold' method to the estimation of extreme wind sped data, we perform Monte Carlo simulations for which the parameters of the population distributions...
On Hurricane-Generated Seas
Two different situations in the relationship between wind speed and sea severity during hurricanes (and tropical cyclones) are clarified from analysis of measured data obtained by NOAA...
