Deformability of Reinforced Concrete Members
A large volume of test data has been evaluated to establish deformability of reinforced concrete beams, columns, and structural walls in the inelastic range. Experimentally observed deformation...
Residual Capacity of Explosively Damaged Reinforced Concrete Columns
The results of load tests on explosively damaged reinforced concrete columns are presented. The method used to correlate an ultimate strength, laminar type of reinforced concrete analysis...
New Roof for an Aging Temporary
The wartime temporary design of a 1942 industrial building justified use of green timber for its roof trusses and higher than usual allowable design stresses. Some 45 years later, a new...
Bells Under Bells
Chicago's newest office tower is supported on new bells that had to be constructed below existing belled caissons. Existing caisson foundations from a previous structure on...
Vibration Analysis Using a Parallel Lanczos Method
A parallel eigenvalue solution algorithm, based on the Lanczos method, has been developed, implemented on a Flexible Computer FLEX/32 multi-processor, and applied to an example structural...
Stochastic Finite Element Analysis of Frames with Flexible Connections
A procedure is proposed in this paper for the stochastic finite element analysis of frames with stochastic connection rigidity. A beam-column element is used to simulate the connection...
Reduction of Imposed Loads for Beam and Column Design
Imposed loads on beams and columns are generally reduced to effect in economy in design. A study to evaluate the reduction criteria by evaluating the Equivalent Uniformly Distributed Loads...
Reliability Study of Randomly Imperfect Beam-Columns
In this study, the effect of random initial geometric imperfections was treated as a set of equivalent random initial forces. This concept enables the direct employment of existing stochastic...
Priority Integrated Pipe Evaluation
The selection of the most suitable pipe for a given site involves the consideration of many factors affecting pipe performance. The factors to consider in sewer pipe evaluation and selection...
A Multilayered Model for Analysis of Composite Pipes
A multilayered model is developed to analyze the behavior of composite pipes, such as prestressed concrete pipe, to the combined effects of internal pressure and applied loads. The pipe...
An Investigation of Field Performance of Reinforced Plastic Mortar Pipes
Every year many new pipe materials appear on the market for various applications. One of the important factors the design engineer and the user should consider while evaluating new products...
Rehabilitation of Terminal Ballast Water Piping
In order to maintain the integrity of the ballast water piping system at the Marine Terminal of the trans-Alaska pipeline, a composite lining system was installed in the 42-inch (1,067...
Cement-Based Materials for Planetary Facilities
The use of concrete and other materials based on a cementitious matrix is evaluated for the construction of planetary base facilities. Consideration is given to the most recent developments...
Response of Advanced Composite Space Materials to Thermal Cycling
In addition to microgravity and lack of atmosphere, the space environment provides intense radiation of both penetrating and nonpenetrating types. This paper focuses on the cyclic radiational...
A Study of Damage in Curved Composite Panels
Composite laminates subjected to a low speed impact, such as a dropped tool or a manufacturing load, often develop an internal delamination. This research studied the effects of a circular...
Progressive Impact Damage Assessment in Composite Pressure Vessels
At the present time, advanced composites have been widely accepted as engineering materials. Analysis techniques for the response of composite materials and structures to static loads...
Composite Construction in Steel and Concrete
Composite steel-concrete systems are used extensively for buildings, bridges, and other civil engineering structures. Research and development related to composite construction are in...
Structure as Architecture
The newest structure at Tampa International Airport in Florida is Airside F, part of an expansion of the first airport designed so that passengers are shuttled via monorail between a main...
Bentonite Matting in Composite Lining Systems
The 1984 Hazardous and Solid Waste Amendments to RCRA mandated that double lining systems utilizing synthetic membrane liners be required for hazardous waste landfills. Recognizing the...
Automating Bridge Design
To avoid some of the pitfalls of manual design calculations, Parsons Brinckerhoff Quade & Douglas engineers designing a series of bridges for a $280 million section of the New...
