Safety of Long Span Highway Bridges Based on Dynamic Response
This paper consists of an analytical study regarding the dynamic response of highway bridges subjected to heavy vehicle loads, with emphasis on long span low fundamental frequency bridges....
The Northwest Watershed Research Center, 1959-86
Hydrologic research has been conducted on the Reynolds Creek Experimental Watershed by the Agricultural Research Service for nearly 27 years. Some noteworthy instrumentation, developed...
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...
Sedimentation Impacts on a Pumpback Storage Facility
Concern over future sedimentation impacts at a proposed pump storage hydroelectric facility at Lake Francis Case on the Missouri River led to use of a numerical model to analyze lake hydrodynamics....
Cracking of a Tilt-Up Structure Due to Dynamic Loads
The extensive cracking of a tilt-up reinforced concrete structure is discussed. The site investigation revealed horizontal cracks at two feet to seven feet above a mezzanine level which...
Nonlinear Axisymmetric Uplift of Circular Plates
A formulation of a method of analysis of the nonlinear axisymmetric response of the bottom plate of a liquid storage tank under uplifting forces is presented. At first, the plate is assumed...
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...
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...
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...
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...
Stability of Cylindrical Shells With and Without Cutouts and Subjected to Wind Load
The cylindrical storage tanks with and without cutouts are analyzed using nonlinear finite element analysis. All the cylinders are fixed at the base. Two types of cylindrical tanks without...
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...
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...
Uncertainties in Wind Loads Caused by Adjacent Buildings
Mean and fluctuating values of all three moment components caused by wind acting on small-scale models of tall prismatic buildings have been measured. Measurements were made in a boundary-layer...
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....
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...
Prediction and Measurement of Wind Response: Case Story of a Wind Sensitive Building
The wind-induced horizontal accelerations of a 43 story office tower in New York City were monitored during 11 occasions over a period of about six months. The building dates back to the...
Measuring the Spatial Characteristics of Unsteady Pressures
This paper has reviewed current methods of determining spatially-averaged time-varying wind loads on wind tunnel building models. Some of the possibilities opened by simultaneous multi-channel...
