Study of the Collapse of a Reinforced Concrete Model Structure Under Simulated Earthquake Motion
The collapse, under simulated earthquake motion, of a multistory r/c frame structure with columns flexurally weaker than beams (SBWC) is studied. A small-scale model, comprising parallel...
Rehabbing for Reuse
Case histories of four building rehabilitation projects highlight special challenges to their structural engineers. The Lits Building, Philadelphia, is a collection of eight structures...
Timber in Bridges of West Coast
Experience has shown that timber can function very well as a bridge material. Proper inspection procedures combined with a structured maintenance program can improve the performance of...
Computer Aided Analysis of Frame Structures
A Plane Frame Analysis (PFA) system is presented. The system analyses structures with prismatic beam and truss elements, elastic supports, internal releases, support settlements, node...
Real Time Data Acquisition in Structural Testing
The process of data collection in real time for structural engineering can be generalized into a process called the real time sequence. The sequence has three major phases: preliminary...
Knowledge Bases for Multistory Concrete Buildings
Heuristics are used in the concrete building industry. A knowledge base is developed with heuristics used in the selection of the floor framing system of a concrete building....
Expert System for Risk Assessment of Concrete Dams
An expert system is presented that will assist a field inspector, during the site investigation of an existing concrete dam, to perform a preliminary structural risk assessment of the...
A Knowledge Based Technique for Structural Component Design Programs
Traditionally, computer programs written for the purpose of sizing and checking standards compliance of individual structural members have been authored in high level compiled languages...
A Demonstration Expert System to Aid in Assessing Groundwater Contaminating Potential by Organic Chemicals
An expert systems approach to evaluating mobility and degradation of organics in soil systems is compared to conventional programming techniques. An expert system has been developed in...
Evaluation and Upgrading of Wood Structures
Case Studies
The need to evaluate and upgrade existing wood structures stems from concerns of safety and serviceability. These concerns are caused for a variety of reasons which include plans for continued...
The Rise of the Tall Building
The development of the high-rise frame in the U.S. was the result of a collision of many factors. The destruction of Chicago in the great fire of 1871 was one major factor in the start...
Building on Water
During the last century, innovations in concrete have paved the way for the evolution of marine concrete structures. Oakland's proposed Carnation Container Terminal is using...
Frame Moments with the Takabeya Method
The Takabeya method of frame analysis, based on the same slope-deflection equations as the Hardy-Cross system, has the advantage of requiring much less memory and fewer computations than...
Logistics for Structures Sealifted to the Arctic
Sohio has successfully pioneered the development of the Prudhoe Bay reservoir by sealifting prebuilt oil processing facilities from the lower 48 states. The experience thus gained is being...
Concrete Space Frame Applied to an Arctic M.O.D.U.
The BOUYGUES experience in the use of concrete space frame technology for civil works and the application of this technique, combined with high strength concrete and prefabrication, to...
Mixing Steel and Concrete
For highrise structures, mixed steel-concrete systems are more efficient and cost less than either material alone. The two design approaches are exterior tube structures and core braced...
Planning Aspects of the Woodward Corridor LRT Preliminary Engineering Project
The efficient deployment of any major project requires careful planning of the management, scheduling and budgeting activities associated with its implementation. The Woodward Corridor...
Watershed Management in 1985
Today's technology in subalpine watershed management is based on carefully designed watershed experiments beginning with Wagon Wheel Gap in 1909. Subsequent advances in process...
Experimental Investigation of Composite Rigid Frames
According to the series of tests conducted by the authors on composite rigid frame models, the compressive principal stress in the steel web plate at the corner panel was considerably...
Mixed Systems: Past Practices, Recent Experience, and Future Direction
A comparison is made between composite column capacities derived from the authors procedure utilizing the ACI (America Concrete Institute) code requirements, and previously published semi-empirical...
