A Generalized Approach to the Local Stability of Stiffened Plates: Part II–Approximate Solution
The paper presents an approximate solution for the prediction of the buckling stress of stiffened plates under combined loadings. A closed form expression is presented for the buckling...

Messeturm Tower: Frankfurt, Germany
A 256 meter (840 feet)tall office tower, currently the tallest building in Europe, has been constructed in Frankfurt Germany. The 7- story structure with 85500 square meter (920,000 square...

Structural Tests on the Suspen-Dome System
The 'suspen-dome' system, which the authors have developed, consists of a single-layer truss dome and a cable structure. The present paper deals with the results of structural tests conducted...

Active Control of Axial Forces in Beam String Space Frames
The present work discusses a formulation for active control of axial forces of strings in beam string structures to dynamically and/or statically reduce the responses, and proves both...

Punching Shear of Reinforced Concrete Shell Structures
In reinforced concrete shells punching shear failure may take place, if heavy concentrated loads are applied. Such failure is undesirable, since it does not provide adequate warning and...

Optimization for Earthquake Loads
Structural optimization for seismic loads can be approached from a deterministic or nondeterministic point of view. Deterministically, the major difference between optimization of statically...

Issues Related to Modeling the Transport of Suspended Sediments in Northern San Francisco Bay, California
Measurements of suspended sediment concentrations at several deep-channel stations in San Francisco Bay are reviewed. Sediment concentrations are found to be strongly correlated with delta...

Comparison of Eulerian-Lagrangian, Random Walk and Hybrid Methods of Modeling Pollutant Transport
An Eulerian-Lagrangian, a random walk, and a hybrid model were compared in terms of their accuracy and efficiency in simulating two-dimensional pollutant transport. Computer experiments...

Modified Asphalt Binders - How Do They Compare?
This report summarizes some of the research that the US Army Engineer Waterways Experiment Station (WES) has conducted on asphalt modification of airport/airfield pavements. these laboratory...

Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...

A User Friendly Microcomputer Program for Liquefaction Potential Analysis
A user friendly microcomputer program is introduced to predict earthquake induced liquefaction and its associated settlement for level ground sites....

Macroelement Model for Shear Wall Analysis
An efficient modeling scheme for static and dynamic analysis of reinforced concrete shear walls in the inelastic range is presented. The macroelement model of the shear wall is composed...

Shear Effects on the Static Behaviour of Stiffened Pierced Walls

Shear Effects on the Free Vibrations of Coupled Shear Walls

Prediction of Settlement of Spread Footings

Replacement of a Failed Embankment Designed to Accommodate Large Settlement: A Case Study
Thick deposits of soft, normally to slightly preconsolidated, organic clay are common at low elevations along the riverbanks of southeast Texas. Both the moisture content and liquid limit...

Environmental Effects of Flooding at a USCG Base
In July of 1993, the U.S. Coast Guard (USCG) Base St. Louis facility was flooded. As the flood waters receded and cleanup efforts were initiated, a number of environmental issues had to...

Anomalous Measurements in a Compound Duct
An anomalous velocity distribution on the 'flood plain' of a compound duct is reported and discussed. The tentative conclusion is that the phenomenon is to be explained by the co-existence...

Measurements of the Hydrodynamic Lift and Drag Forces Acting on Riprap Side Slope
Direct measurements have been made of lift and drag forces acting on a 20.1 mm spherical particle placed within the riprapped 1.5 H: 1 V side slope of a 10 m long channel which was protected...

Simultaneous Flow Visualization and Hot-Film Measurements
High-speed video recording of flow visualizations in the near wall region of a turbulent open channel flow was synchronized with hot-film measurements of flow velocity and bed shear stress...
