Evaluation of Stormwater Management Structures in Maryland Proportioned by SCS TR-55
Various state and local agencies in Maryland are requiring that the Soil Conservation Service Technical Release 55 be used to evaluate impact of urbanization on peak rates of discharge....
Overview--Committee Report on Dam Safety Guidelines
In November 1984 the Surface Water Hydrology Committee appointed a task committee with the assignment to suggest standards for the hydrologic safety design of dams. The committee report...
Criteria for Spillway Design Floods
The procedures outlined in this paper only address the hydrologic safety criteria for spillway design floods. The recommended procedures are based on a careful identification of the social,...
Indemnification Costs in the Dam Safety Decision
The ASCE Task Committee on Spillway Design Floods has proposed safety criteria for three categories of dams. Category 1 dams are those with anticipated failure consequences so large and...
Utility Programs for DWOPER and DAMBRK
Time and computer resources greatly limit potential investigations and sensitivity anslyses. In order to facilitate modeling with the National Weather Service (NWS) programs DWOPER (Operational...
Safety Design Flood for Too Wide Creek Dam
This paper presents an example application of the procedure developed by the ASCE Task Committee on Spillway Design Floods for a dam on the Too Wide Creek. The example was developed from...
Criteria for Selecting a Reservoir Routing Method
Results of an investigation comparing dynamic and storage reservoir routing applied in dam safety analyses are presented. Outflow hydrographs computed by these reservoir routing methods...
Serviceability Limit States in Load Space
Deflection and elastic limit state curves are drawn in load space using a nonlinear structural analysis program. Use of load space simplifies computation of point estimates of serviceability...
Probabilistic Models of Fatigue Crack Growth
The reliability of a structure against metal fatigue is a problem that has been of concern to engineers for a very long time. This problem was one of the first to be approached probabilistically,...
Applications of Fiber Bundle Model to Structural Engineering
The bundle failure time has been studied extensively for both deterministic and random loads. The objective of this paper is to apply results in these studies to the dynamic analysis of...
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...
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...
Probability of Facility Damage From Extreme Wind Effects
A probabilistic methodology has been developed to assess the risks of extreme wind induced damage to structures and facilities. The wind effects considered include dynamic pressure, atmospheric...
Evaluating Mitigative Options for Critical Facilities in Hurricane Prone Regions
This paper describes, and demonstrates the use of, a methodology to evaluate the safety of occupants in structures subjected to hurricane forces. Occupant safety is expressed in terms...
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...
Research Needs to Resist Terrorist Attacks
The task of protecting facilities against terrorist attacks is very much a new problem for the U. S. civilian sector. Guidance as to what steps need to be taken by a municipality or a...
Rational Design Approach for Tension on the Net Section
A study of the bearing and net section capacities of bolt connections for material thicknesses encountered in cold-formed members was conducted. This paper summarizes the findings as they...
Bending Strength of Thin Cold-Formed Steel Straight Panels
An experimental investigation on the bending strength of 26 gage cold-formed corrugated steel straight panels with web-depth to thickness (h/t) ratio of 475 is presented. A typical test...
Behavior and Design of Semi-Rigid Composite Frames
Recent advances and experimental research on the behavior of composite semi-rigid frames indicates that substantial savings can be achieved with this method of construction. The current...
