Dynamic Response of Highway Guardrail Post Foundations
The highway departments use two types of guardrail posts: a circular wood post and a steel W6 multiplied by 8. 5 post. The current specifications require the steel post to be placed in...
Dynamic Behavior of Full-Scale Wood Diaphragms
Experimental testing of full-scale wood diaphragms has been performed at Washington State University to determine basic dynamic properties. Ten diaphragms, including walls, floors, and...
Response of Underground Pipelines to Dynamic Loads
The results of an investigation of the forced response of an underground pipeline due to dynamic loads are presented. The pipe is modelled as a linearly elastic shell element and the surrounding...
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...
Hysteretic Behavior of Precast Cladding Connections
A preliminary experimental study is presented which investigates the behavior of connections for architectural precast concrete cladding panels. The principal objective is to quantify...
Interdependence of Dynamic Analysis and Experiment
This paper emphasizes the importance of experimental research to the development of reliable analytical methods for predicting the behavior of structures subjected to static or dynamic...
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...
The Atlantic Palace: Part I Structural System Selection Based on Wind Tunnel Testing
The location of the structure in a coastal area susceptible to high winds, the irregular shape and height of the building and the desire for more accurate wind loading and acceleration...
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...
Structural Dynamics in Hurricanes and Tornadoes
The random fluctuations of wind gusts produce dynamic interaction with structures. The objectives of this paper are to identify distinguishing differences in hurricane and tornado winds...
Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...
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'...
Settlement of Light Buildings on Loose Sand
This paper reviews several cases of settlement of lightly loaded structures supported on granular soils. The concept of settlement ratio is presented. Measurements indicate that the settlement...
Settlement of a Reactor Containment on Sand
In this paper, predicted and observed settlements are presented for the reactor containment structure of the Beaver Valley Power Station - Unit 2, Shippingport, Pennsylvania. The Beaver...
Dynamic Response Correlation Using Simplified Models
A simplified model for building response which has a W. Ramberg-W. R. Osgood hysteresis is developed in a discrete sense. It is then used to evaluate the response of an instrumented, bearing...
Large Scale Testing Facility for the Evaluation of Structural Systems Under Critical Loads
The Charles Lee Powell Structural Systems Laboratory at the University of California, San Diego, provides, with a 50 ft. high reaction strong wall and a 120 multiplied by 50 ft. box girder...
Performance of an Earthquake Excited Roof Diaphragm
The objective of this paper is to study the earthquake performance of the roof diaphragm of the West Valley College gymnasium in Saratoga, California through a complete set of acceleration...
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...
