Response of Buried Structure Walls to Earth Penetrating Conventional Weapons
A structural analysis method is presented which accurately models the interface condition between a buried structure and the surrounding soil. During the loading phase, continuity of both...

Combined Finite Difference/Finite Element Analysis for Soil Structure Interaction
A method for the analysis of buried structures subjected to stress transients is presented. The method combines the finite difference and finite element techniques to provide the analyst...

Dynamic Response of Massive Block to Transient Rayleigh Waves
The study explores the dynamic behavior of a rigid massive block placed on a homogeneous elastic half-space soil medium and subjected to transient Rayleigh waves. The treatment of the...

Improved Design Procedure for Shallow-Buried Structures to Resist Airblast Loading
Both conventional and nuclear weapons generate airblast loads of sufficient magnitude that structure survival at acceptable cost favors below grade construction. The design of shallow-buried...

Anchorage Forces for Z-Purlin Supported Standing Seam Roof Systems
This paper presents the results of a limited study to determine if the provisions of Section D. 3. 2. 1 'Anchorage Bracing for Roof Systems Under Load with Top Flange Connected...

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...

Centrally Loaded Columns
The paper has given a detailed description of the chapter on centrally loaded columns that will appear in the 4th Edition of the Structural Stability Research Council 'Guide...

Effect of Connector Spacing on Double Angle Compressive Strength
The 1986 AISC 'Load and Resistance Factor Design (LRFD) Specification for Structural Steel Buildings' includes new rules affecting the design of built-up members...

Reliability-oriented Design of Fatigue Experiments
It is well known in the reliability analysis for structural components subjected to cyclic random load that apart from the usually model parameters uncertainties are most important and...

Polymer Concrete for Structural Applications
Polymer concrete (PC) has been used extensively in the United States primarily as a repair material for portland cement concrete. The excellent flexural and compressive strength durability...

Chemical Admixtures for Concrete, What is in Them for the Structural Engineer?
The paper summarizes the effect of admixtures on the economy in construction of concrete structures, on their strength, and on their durability under a variety of service conditions. As...

High Strength Concrete - A New Material
In this paper, the material properties and structural member behavior of normal and high-strength concretes are summarized. The current ACI code recommendations are based on results of...

Concrete Shell Design for Membrane Stress
A methodology is presented which covers the design of reinforced concrete shells for membrane stress. The methodology follows the strength design method of the ACI 318-83 Building Code...

Ultimate Membrane Strength of R/C Shell Elements
The ultimate strength of reinforced concrete shell elements is governed by the yielding of steel and/or the compressive strength of concrete. Depending on which of these two conditions...

Second Order Analysis of a 47-Story Building
A modern day second order analysis and ultimate strength review is made of a hypothetical 47-story unbraced frame designed under the 1969 AISC Specification. The original design is part...

Geotechnical Practice for Waste Disposal '87
This volume contains 55 papers covering many aspects of geotechnical issues associated with waste disposal. The papers represent advances during the intervening decade since the first...

A Burning Wasteland Reclaimed
Until recently the PJP Landfill exemplified what can happen when uncontrolled and illegal dumping goes on for many years. Now it is an example of what innovation and imagination can do...

Treating Expansive Soils
Damage that expansive soils do to light buildings can often be prevented or mitigated by preconstruction soil treatment. Treatments of three kinds are described�reworking the soil, controlling...

Tunnel Saved by Flyash
When inspection early in 1986 showed that Detroit's Northeast Raw Water Tunnel was near collapse at one location, quick action and a unique use of flyash-cement grout or fill...
