Slab Participation in Frames under Lateral Loads
A unique opportunity to study slab participation was afforded by the U. S. -Japan Cooperative project on large scale testing. The data obtained from the full-scale 7-story building tested...
Evaluation of Seismic Strengthening of an Existing Building Using Base Isolation
This paper summarizes a study performed by Englekirk and Hart, Inc. to evaluate the feasibility of using base isolation to seismically upgrade an existing highrise building. To realize...
Earthquake Response of Five Story Reinforced Concrete Masonry Test Building
In 1986, a full-scale five story reinforced masonry test building is to be constructed in the Japan Building Research Institute Large-Scale Structure Test Laboratory, and through 1987...
Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...
Modeling for Finite-Element Soil-Structure Interaction Analysis
The modeling for finite-element soil-structure interaction analysis for embedded structures is evaluated in an attempt to resolve the issue related to the elevation at which design ground...
Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...
An Experimental Study of Active Structural Control
An experimental investigation is made concerning the possible application of active control to structures under seismic excitation. The experimental facilities and structural model are...
Cladding Design for Tall Buildings
In the past twenty years, glass cladding has emerged as a popular and economic building material. Its use in tall buildings which are constructed in high-risk wind and seismic geographical...
Seismic Isolation of Bridge Structures
Seismic isolation concept has been extensively developed and applied in New Zealand and is receiving increased attention in the United States. Two bridge projects have incorporated the...
The Atlantic Palace?Part II The Application of Wind Tunnel/Force Balance Techniques
A relatively new approach for determining overall wind-induced loads on a structure is described. This force balance technique is economical and flexible, and able to provide predictions...
A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...
It's Only Visual Inspection (Welding Inspection)
Unless specified otherwise in the Contract Documents, Visual Inspection will be performed on all fabrication/erection welding for projects that utilize the Specifications for the Design,...
Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...
Pressuremeter and Shallow Foundations on Sand
The settlement and bearing capacity rules for the design of shallow foundations on sands using the results of pressuremeter tests are reviewed. The results of four footing tests to failure...
Structural Settlements at a Major Power Plant
The foundation design for the Intermountain Generating Station was based on comprehensive geotechnical investigations that included cone penetrometer tests, borings, pressuremeter tests,...
Experimental Studies, Structural Design and Full-Scale Measurements for the Columbia Seafirst Center
The Columbia Seafirst Center is a 76-story office tower located in downtown Seattle, Washington. It rises to a height of about 940 feet above ground and is the world's 10th...
Damping in Tall Buildings: Its Variability and Treatment in Design
Increasingly, damping is being recognized as an important factor in the design of structures. It is at the same time a property which is relatively poorly defined, more acquired than engineered...
Damping Systems to Limit the Motion of Tall Buildings
Two types of damping systems have been used successfully in building applications - the Tuned Mass Damper, and Viscoelastic Damping Units. In the past, Tuned Mass Dampers were used in...
Design of Viscoelastic Dampers for Columbia Center Building
To reduce the dynamic response of a building with a given height and plan area to wind load, aside from inherent damping of the building, the designer has a few options available to him/her....
Performance of Viscoelastic Structural Dampers for the Columbia Center Building
Vibratory motion of structures such as buildings, bridges, and floors can be reduced by the use of viscoelastic (V. E. ) dampers. Such dampers transfer part of the vibratory energy of...
