Stress-Strain Behavior of Grouted Hollow Unit Masonry
Experimental results from axial stress-strain tests including post-peak response on hollow unit masonry prisms are compared to those of previous researchers....
Problems of Spectral Analysis in Dispersion Tests
The use of dispersive surface waves and spectral analysis methods is new to the nondestructive testing of airfield pavements. Such tests are to determine whether mechanical properties...
Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...
Stochastic Response for Tertiary Systems
A modal superposition method is presented for obtaining the response of a single-degree-of-freedom tertiary subsystem mounted on a primary-secondary system. The method is direct in that...
Rigid Body Random Rocking Prediction
The stochastic rocking of a rigid block due to shaking of its foundation is examined. The foundation is flexible (Winkler) and its independent springs and dashpots separate from the block...
Stochastic Response of Structures with Appendages Containing Fluids
Following a perturbation technique a procedure is developed to compute the modal properties of a system consisting of a fluid containing appendage attached to a multi-degree-of-freedom...
Optimal Control of Seismic Structures
This paper presents the algorithm for optimal design of structural systems with active tendon controllers and/or active mass dampers. The structure is subjected to earthquake excitation...
A Stochastic Source Spectrum for Engineering Application
The solution of a point source (double couple) combined with K. Aki/A. S. Papageorgiou's stochastic source model is used to establish the power spectrum at the acceleration...
Engineering Laboratories' Role in Quality
Quality construction of a quality design is one goal which Owners, Design Professionals, and Contractors can all agree is needed if the project is to be truly successful. The Engineering...
Development of Second Generation Plasticized Sulfur Binders as a Paving Material
Plasticized sulphur is produced when melted sulphur is reacted with selected hydrocarbons to produce polysulfides. These polysulfides help retain a 'polymeric'...
Large Scale Testing Facility for the Evaluation of Structural Systems Under Critical Loads
The Charles Lee Powell Structural Systems Laboratory at the University of California, San Diego, provides, with a 50 ft. high reaction strong wall and a 120 multiplied by 50 ft. box girder...
The Parking Problem
Corrosion of parking garage decks has become a multi-billion dollar problem, caused primarily by deicing salts that seep into the concrete and attack reinforcing steel. Design and construction...
Roof Membranes: New Systems, New Problems
Market trends in roof membranes are described; most important is the use of single-ply membranes of rubber or plastic in the past decade. A swing to modified bitumen membranes is predicted...
Pavement?An Integral Part of the Terminal as a Container Handling System
A modern container terminal requires extensive areas of paving for stacking and moving containers, the provision of which often proves to be one of the most expensive single items, in...
Pavement Design for a Break Bulk Terminal Yard
This paper discusses the practical application of mechanistic pavement design principles for a proposed 8. 1 ha break bulk cargo storage yard that is part of the Port of Portland's...
Tacoma Sea-Land Terminal: A Project Management Challenge
The Port of Tacoma completed a new two berth container terminal and intermodal yard for Sea-Land in May 1985 in only 26 months after signing a binding agreement. The project, which also...
Tacoma Terminals Pier Designed for Economy
This pier is a representative and highly refined sample of what is known as the Puget Sound system of construction, an economical system that maintains the durability necessary in the...
Designing Marinas to Mitigate Impacts
The John Wayne Marina was permitted for construction only after certain design features were altered to accomodate major biological and water quality concerns. The moorage basin was relocated...
Research on the Strength Characteristics of Timber Piling
Research on the strength characteristics of wet Southern Pine and Douglas Fir piling and poles is presented. Included are background information on wood's strength characteristics,...
Structural Design of Container Cranes
The shipping industry uses container cranes to move cargo containers on and off ships. Container cranes have characteristics common to all crane structures, but many characteristics are...
