An Analysis and Comparison of Probable Maximum Floods with 10,000-year Frequency Floods and Maximum Observed Floods for Spillway Design
The use of deterministic probable maximum floods are supported in part by the conclusions of an Interagency Work Group formed to address the following questions: (1) Is it within the state...

Fault-Tolerant Design for Data Acquisition and Flood Forecast Systems
An innovative fault tolerant flood warning system is currently being installed in the Passaic River Basin. The new system is designed to automatically tolerate the failure of major components...

A Comparative Study of Different Base Isolators
A comparative study of the effectiveness of four different base isolators is carried out. The structure is modeled as a rigid mass and the accelerograms of the North-South component of...

Seismic Response of Simple Structures with Coulomb Damping
A single story structure incorporating a floor-sliding mechanism for dissipation of vibration energy through Coulomb friction damping is examined. The response of this structure is evaluated...

Dynamic Behavior of R/C Buildings in Vi? del Mar, Chile
The Chilean earthquake of 3 March 1985 resulted in an effective peak acceleration of 0. 36g in the coastal city of Vina del Mar. The city had an inventory of over 400 reinforced concrete...

Methods for Improving the Seismic Response of Concentrically Braced Steel Frames
This paper briefly reviews various factors contributing to the poor performance occasionally observed in concentrically braced steel frame structures during recent earthquakes. Several...

Unusual Shaped Highrise Buildings in Seismic Zone
The structural concepts, seismic analysis and design of five recent highrise structures are presented in this paper. The paper deals with the problem of multistory buildings having 'structural...

The Design and Construction of the Washington State Convention and Trade Center Over Interstate 5
The Washington State Convention and Trade Center is a 10-level, 1,000,000-square foot facility constructed over Interstate 5 in downtown Seattle. The project spans over three city streets...

Unified Approach to Reliability-Based Structural Optimization
The purpose of this paper is to present a unified approach to reliability-based structural optimization. The emphasis is placed on recent developments in the field including optimal design...

Application of Normal Integration Formulas to Bridge Reliability Analysis
Structural reliability analysis often involves extensive integration of complex multivariable functions. Special techniques can be used to reduce this numerical effort. This paper deals...

Geologic Assessment of Seismotectonic Hazards
Design and modification of dams require evaluation of potential seismotectonic hazards based on consideration of the historic earthquake record and deterministic evaluation of geologic...

Seismic Response Component in the Risk Assessment of Dams
The risk analysis model for dams that is discussed in this paper considers the probability of an initiating event and the following conditional probabilities of the system response, the...

Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...

Optimum Cut-Outs on Plate Stability
Cut-outs are unavoidable in some of the plate components. To minimize the plate weight, in the meantime, to maintain the critical buckling load as high as possible is one of the major...

Behaviour of Thin-Walled Channel Sections in Bending
The effects of local buckling on the behaviour and load carrying capacity of thin-walled cold formed steel plain channel sections is examined. The bending is applied in such a way that...

Simplified Steel Compression Member Design
The objective of this paper is to present a simplified method of designing steel columns subjected to axial loads and moments for use in situations where automated design methods are inappropriate....

General Considerations for Seismic Stability
The basic design consideration is provision of sufficient stiffness, strength and adequate ductility for the varied loads imposed on the building. Adequate stiffness is needed to resist...

Code Designed Steel Frame Performance Characteristics
Three similar steel ductile moment-resisting frame structures designed in accordance to the Uniform Building Code (1976-1985) are evaluated for their performance characteristics during...

Maximum Response of Buildings to Multi-Seismic Input
The paper presents a technique of determining the maximum response of a torsionally-translationally coupling structure subjected to three ground translational components. It was found...

Cyclic Behavior of Concrete-Filled Tubes
This paper presents the results of tests on hollow and concrete-filled rectangular tubes subjected to cyclic bending and buckling. It is shown that concrete infill greatly improves the...
