Muskingum Flow Routing Using Personal Computers
The paper discusses how tedious computations involved in flow routing can be easily implemented on Personal Computers. Parameter estimation and routing calculations for both linear and...

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...

Legal Misuse of Urban Hydrology Concepts and Regulations for Rural Areas
This paper presents recent observations of the misuse of technical definition, hydrologic concepts, sedimentation engineering principles, and flood control regulations by the legal profession...

Time Base of a Hydrograph
For design projects in water resources, a hydrograph is commonly used to determine the required flood volumes. The time base of a hydrograph is a crucial parameter in such studies, and...

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...

Response of Structures to Horizontal-Vertical Earthquakes
In the present work, the responses of a class of hysteretically nonlinear structures subjected to the combined horizontal and vertical random ground accelerations are studied. A massless...

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...

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...

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...

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...

Lateral Impedance of Contact Pile Foundations
The static and dynamic lateral impedance of pile foundations for which there is continuous contact between the bottom of the pilecap and the underlying soil is investigated. A parametric...

Risk Assessment for Cladding Panels: An Expert Systems Approach
Risk assessment for structures in the context of wind engineering involves many factors such as wind hazard, the wind sensitivity of the structure and the socio-economic value of the structure....

The Risk of Progressive Collapse of Single-Story Buildings in Severe Storms
The probability of severe damage and progressive collapse of single-story commercial, institutional and residential buildings is examined. Observations of actual damage and the results...

Assessment & Control of Wind Created Risk During Construction
Structures under construction have been damaged by winds. The damaging winds, typically, are much lower than the design wind loads for completed structures. Little guidance is available...
