Getting Finite Element Programs to Reason About Their Analysis Assumptions
Despite the spectacular improvements of finite element analysis programs, there has been no corresponding progress in the development of physical modeling and interpretation aids. The...

Optimal Location of Active Controllers Subjected to Seismic Excitation
In the application of structural control to seismic structures certain locations are advantageous for placement of the actuators. These locations reduce the structure's response...

An Object-Oriented Model for Building Design and Construction
This paper describes the initial work done in developing a modelling environment which captures both functional and spatial aspects of a building, abstract and detailed descriptions, and...

Seismic Large Amplitude Liquid Sloshing—Theory
The sloshing phenomenon in seismically-excited, rectangular, liquid storage tanks is addressed. In particular, a semi-analytical method to study the effects of large amplitude sloshing...

Biaxial Damage Assessment
The structural system under investigation is a frame subject to seismic excitations. The analysis accounts for the spatial distribution of beams, columns and bracing system. It also considers...

Effects of Semi-Rigid Connections and P-Δ Forces on the Optimum Design of Seismic Steel Frames
By utilizing methods of optimality critera and constraint gradients, the minimum weight design of semi-rigid planar steel frames subjected to static and seismic excitations is presented...

Physical Model Study for Proposed Harbor Expansion

Constraint Based Design from Research into the Classroom
Design is constraint oriented; much of the design process involves the recognition, formulation and satisfaction of constraints. Constraints are continually being added, deleted and modified...

The State of Art of Physical Modelling of Sediment Transport
The paper attempts formula some ideas about the state of the art in the field of physical modelling of sediment transport processes. Up to now the physics of sediment transport are not...

Total Sediment Transport and Its Physical and Mathematical Modeling
Some main results in the field of sediment transport theories obtained by the author are presented. Based on these theories, the methods of physical and mathematical modeling for total...

Mid-Scale Laboratory Tests on a Two-Dimensional Movable-Bed Sand Model
A two-dimensional physical model was used to simulate wave-induced scour in front of a concrete dike sloped at 1:4. The tests were conducted at the U.S. Army Engineers Waterways Experiment...

Sediment—Hyperconcentration Flow and Its Similarity Laws
The sediment- hyperconcentration flow are studied theoretically and experimentally, and the formulas for the Bingham shear stress, rigidity coefficient, fall velocity and transport capacity...

Partnership in Environmental Design for Brush Creek Flood Control
Brush Creek drains a highly urbanized area in metropolitan Kansas City. A large physical model was used to develop a channel modification design for flood control. The Parks and Recreation...

Model Study of Potential Debris Problems at the Proposed Diversion of Clover Fork River, Harlan, Kentucky
A study was conducted at the Waterways Experiment Station in Vicksburg, Mississippi, using a physical and a numerical model, to evaluate the entrance conditions at a proposed tunnel diversion...

Hydraulic Model and Prototype Experience on Old River Overbank Structure
Physical hydraulic model tests of the Old River overbank structure were conducted to investigate the hydraulic performance of the stilling basin and evaluate riprap stability and scour...

Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...

Physical Modeling of Heated Discharges into a Stagnant River
An alternative cooling system study was performed for the Damietta Combined Cycle Plant in Egypt. The alternatives included spray canals, helper cooling tower and once-through cooling....

Jet Injection Model Studies for the City of Los Angeles
