A Multi-User Fender Design and Installation
The increase in damage frequency to the existing Timber Fender System during the change-over from military to commercial/industrial users resulted in a call for design solutions from the...
CAD Goes into Analysis
In the past, computer analysis of a design was always a separate and distinct step from CAD. Now, an increasing number of systems are combining the two. One system, SSCAD, allows the engineer...
Incorporating Judgment into an Optimization Model of a Wastewater Treatment System
The use of design variable constraints according to textbook and state design standards might cause potentially good designs to be missed and would not capture the fuzzy interaction of...
Investigating and Treating Chromium in Ground Water at a Wood Treater in California
A wood treating facility, operating for more than five years without required permits, contaminated soil and ground water on and offsite. The company moved slowly in response to enforcement...
Evaluation of PCP/Oil Spill on CFT Indian Reservation Near Nespelem, Washington
This paper presents the immediate action taken, the field work performed, and the engineering analysis performed in response to a spillage of a solution of pentachlorophenol (PCP) and...
Long Reinforced Concrete Columns
Papers selected by the Reinforced Concrete Research Council of ASCE. This collection contains 13 papers reporting the results of a series of studies,...
Restoration of Navy LTA (Lighter Than Air) Hangars
In 1942 and 1943 the Government constructed a series of 16 blimp hangars at ten Naval Air Stations along the east coast, west coast and gulf coast. The hangars erected in pairs housed...
Use of Nondestructive Testing in Rehabilitation of Wood Cooling Towers
State-of-the-art nondestructive evaluation (NDE) techniques, destructive testing, structural analysis, degradation rate models and statistical analysis are combined to optimize a major...
Decay in Wood Structures
One of the main causes of wood deterioration is decay. Decay causes millions of dollars in damage to timber structures each year. Left unchecked, decay deterioration can become a structural...
Case Studies in Upgrading of Wood Trusses and a Heavy Timber Building
Three case studies in upgrading and rehabilitation of wood structures are presented. One case study relates to three 30m (100ft) span bowstring trusses that had to be cut at various span...
Epoxy Repair of a Glulam Beam
The repair of timber structures by epoxy injection techniques is a recently developed repair alternative. Theoretical and experimental studies have resulted in the formulation of design...
Hypars and Wood Shells?The Boston College Recplex
For the past twenty years, we have been involved in the design and construction of intermediate span wood hyperbolic paraboloid. During that time the spans have ranged from 50 ft. to 200...
Nondestructive Evaluation of Timber Bridge Piles
A nondestructive technique for the determination of the in-place strength of timber bridge piling is presented herein. The testing technique is the ultrasonic wave propagation method in...
Alterations to Old Wood Building
In order to accommodate a new use, a request was made to remove bearing walls supporting the roof of a 42 year-old building and substitute timber posts. The existing nine-foot ceiling...
Evaluation of the Seismic Performance of Buildings
The aim of the paper is to present the different existing methodologies available for the assessment of seismic damage to buildings. The approach aims towards the development of a mini-computer...
Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...
Probabilistic Limit States Design of Moment-Resistant Frames Under Seismic Loading
This paper focuses on the development of a methodology for the optimal probabilistic limit states design of seismic-resistant steel frames. A mechanism for allowing the designer to include...
Connection Panel Zone Deformation in Steel Frames
Conventional analyses of frameworks are usually carried out without considering the effect of panel zone deformation on frame behavior. As a result, center-to-center distances rather than...
Seismic Design of Braced Steel Frames
Seismic behavior of a six-story, K-braced structure without backup ductile moment-resisting frames designed according to the current Uniform Building Code is studied in this paper. The...
The Effects of P-Delta and Semi-Rigid Connections on Response Behavior of Inelastic Steel Frames Subjected to Cyclic and Seismic Loadings
A numerical method is presented for analyzing semi-rigid connected steel frames subjected to various time-dependent excitations with consideration of damping, nonlinear material behavior...
