How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...

Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...

Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...

Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...

U.S.-Japan Coordinated Program on Masonry Research
An overview of the U. S. -Japan Coordinated Program on Masonry Research is presented. The program consists of parallel efforts in Japan and the United States to develop design methods...

Hysteretic Behavior of Composite Diaphragms
Floor systems constructed with steel-deck-reinforced concrete are described. When used to resist lateral loads these systems are referred to as diaphragms. A description of a test arrangement,...

Refinements in Pseudo-Dynamic Test Procedures
One of the major concerns in seismic testing is whether the loading conditions imposed on a structure adequately represent those that might occur during a major earthquake. Response simulation...

Performance of Existing Buildings: Results of Benchmark Structure Analyses Performed in U.S.-Japan Workshops
In response to the need for better understanding of current safety evaluation methodologies, three U. S. -Japan workshops have been conducted on the evaluation of the performance of existing...

Strengthening of a Multi-Story Building with Deflection Constraints
Occasionally the existing structural or nonstructural systems of a building being strengthened require the imposition of deflection constraints or limits in order to avoid an undesirable...

On Reliability-Based Structural Optimization for Earthquakes
Previous studies of reliability-based structural optimization have been extended in order to investigate the applicability of the linear statistical model in cases where random parameters...

Three Phase Design for Wind Loads on Structures
The successful design of a structure requires three phases of work. These phases are: conceptual design, design development and design verification. The conceptual design is undertaken...

Seismic Behavior of a Full-Scale K-Braced Steel Frame?Part I Gross Behavior
As a part of the U. S. -Japan Cooperative Research Program Utilizing Large-Scale Testing Facilities, a six-story, 2 by 2 bay, concentrically K-braced steel building was constructed in...

Seismic Behavior of a Full-Scale K-Braced Steel Frame?Part II Local Behavior
The full-scale six-story concentrically K-braced steel building was subjected to Miyagi-Ken-Oki simulated earthquake whose peak intensity was 500gal. Local behavior of the test building...

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...

The Earthquake Barrier
The earthquake barrier protects buildings from the horizontal ground vibrations of an earthquake by installing a 'force barrier and an energy barrier' at the...
