Predictions of Thermally Induced Stresses in Thin Walled Grain Storage Bins Under Declining Ambient Temperatures
A generalized constitutive equation for cohesionless sands based on elasto-plastic theories is applied to a grain bin system. The validity of the theory is established through the finite...
Measuring Dynamic Occupant Loads by Microcomputer
Present building codes regard live loads caused by human movement as deterministic; values are based upon experience and tests run in 1912, 1922, and 1932. An experimental project to statistically...
Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...
Integrated Design of Concrete Flat Plate Structures
An integrated structural design and drafting system for concrete flat plate floor systems is described. This system provides at a single computer workstation the tools necessary to layout...
How To Design Highway Retaining Walls?A Practical Application of CADD
The recent work developed at the University of Missouri-Rolla (UMR) including optimization algorithms and two computer programs, ODSEWS-2D-II and ODRESB-3D are discussed. Several numerical...
Analysis and Optimum Design of Nondeterministic Structures under Random Loads
The importance of analyzing and designing structural systems by using a reliability-based approach is emphasized, including system safety requirements with regard to both serviceability...
Animated Response of Dynamic Systems
Understanding how a simple structural system responds to a dynamically applied load is a difficult concept for most students to grasp. The fundamental mathematical theory of this behavior...
Nonlinear Analysis of RC Panels Under In-Plane Loading
A new concrete material model based on a modified Mohr-Coulomb criterion is proposed for the nonlinear analysis of reinforced concrete panels. Emphases are made on the softening behavior...
Evaluation of Safety Alternatives by Benefit/Cost Analysis
There is an increasing awareness of the need to use limited highway safety funds on projects that offer the greatest benefits. This paper describes the development and application of a...
Performance of Highway Traffic Barriers
This paper describes an investigation of traffic barrier performance in New York State. A one-year sample of all traffic-barrier accidents in the state was obtained from Department of...
Transitioning End Terminal A TRENDtm for the Future
The highway engineer frequently starts from a position where an identified highway element is causing serious injuries or fatalities to motorists on the nation's highways....
Hazardous Events After Redirectional Collisions
The potential for hazardous events occurring to vehicle occupants after a redirection from a longitudinal barrier has not been adequately addressed. Very few studies are available which...
Occupant Risk in Longitudinal Barrier Collisions
The following paper presents data derived from sled test experiments, full-scale vehicle crash tests as well as an in-depth analysis of accident data which suggest that occupants are not...
Shear Mobilization on Laterally Loaded Shafts
From the results of a pressure cell instrumented rigid shaft embedded in stiff clay and subjected to horizontal static loading the side shear mobilization rate, and its contribution to...
Seismic Acceleration Maps for Oregon
To evaluate the seismic hazard for the Corps dams in the Portland District, operating basis earthquakes (OBE) and maximum credible earthquakes (MCE) were established for seismic zones...
Seismic Resistance of an Elevated Water Tank?A Case Study
Current knowledge of earthquake risk and structural response has raised concern about the safety of elevated water storage tanks which were constructed several decades ago. This paper...
Attaching Steel Members to Reinforced Concrete Elements
A variety of structural systems have been devised to strengthen existing buildings for improved seismic resistance. Strengthening methods currently in use for reinforced concrete structures...
Design of an Expert System for the Rating of Highway Bridges
A microcomputer-based expert system used to determine the effects of vehicles and overloaded vehicles on simple span bridges with reinforced concrete deck and prestressed concrete I-beams...
RC Structures Under Severe Loads?An Expert System Approach
The authors propose the application of expert systems to the post-test assessment of specific structural systems. In the study reported, an existing expert system shell was employed and...
Assessment of Safety Impacts of Highway Projects
In this paper the safety impact of highway improvement and maintenance activities is examined in terms of accident reduction potentials of these activities. There are three causes of accident:...
